Importance of Wall Thickness in Injection Molded Parts
When designing injection molded parts, it is important to keep the wall thickness uniform. Uneven wall thickness can lead to warping and sinking. To minimize these problems, injection molded parts should have a wall thickness of 40 to 60 percent of the adjacent wall. The thickness of the wall should also fit within the range recommended for the resin that is being used. If the wall thickness is too thick, it should be cored out. Unnecessary wall thickness alters the dimensions of the part, reduces its strength, and may require post-process machining.
Designing out sharp corners on injection molded parts
Designing out sharp corners on injection molded components can be a challenging process. There are several factors to consider that impact how much corner radius you need to design out. A general rule is to use a radius that is about 0.5 times the thickness of the adjacent wall. This will prevent sharp corners from occurring on a part that is manufactured from injection molding.
Sharp corners can obstruct the flow of plastic melt into the mold and create flaws on parts. They can also cause stress concentration, which can compromise the strength of the part. To avoid this, sharp corners should be designed out. Adding radii to the corners is also an effective way to avoid sharp angles.
Another common problem is the presence of overhangs. Injection molding parts with overhangs tend to have side-action cores, which enter from the top or bottom. As a result, the cost of making these parts goes up quickly. Moreover, the process of solidification and cooling takes up more than half of the injection molding cycle. This makes it more cost-effective to design parts with minimal overhangs.
Undercuts on injection molded parts should be designed with a greater radius, preferably one or two times the part’s wall thickness. The inside radius of corners should be at least 0.5 times the wall thickness and the outside radius should be 1.5 times the wall thickness. This will help maintain a consistent wall thickness throughout the part. Avoiding undercuts is also important for easy ejection from the mold. If undercuts are present, they can cause a part to stick inside the mold after it has cooled.
Keeping wall thickness uniform is another important issue when designing plastic parts. Inconsistent wall thickness will increase the chance of warping and other defects.
Adding inserts to injection molded parts
Adding inserts to injection molded parts can be a cost-effective way to enhance the functionality of your products. Inserts are usually manufactured from a wide range of materials, including stainless steel, brass, aluminum, bronze, copper, Monel, nickel/nickel alloy, and more. Selecting the right material for your parts depends on the application. Choosing the correct material can help prevent defects and keep production cycles short. The insert material should be durable and resist deformation during the injection molding process. It must also be thin enough to provide the desired grip and have a proper mold depth.
The benefits of adding inserts to injection molded parts include the ability to design parts with unique shapes. These parts can be aesthetically pleasing, while still remaining durable and resistant to wear and tear. In addition, insert molding allows products to have a good external finish. In addition to being cost-effective, insert molding is considered a more efficient manufacturing method than other conventional methods.
Adding inserts to injection molded parts is an excellent way to enhance the strength and performance of your products. There are many different types of inserts, including threaded nuts, bushings, pins, and blades. Some types are even available with knurled outer surfaces that help them adhere to plastic.
In addition to being cost-effective, insert molding is environmentally friendly and compatible with many types of materials. Typical inserts are made of metal or plastic. Depending on the application, stiffening inserts may also be made from wood.
Importance of uniform wall thickness
The uniformity of wall thickness is an essential factor in the plastic injection molding process. It not only provides the best processing results, but also ensures that the molded part is consistently balanced. This uniformity is especially important for plastics, since they are poor heat conductors. Moreover, if the wall thickness of an injection molded part varies, air will trap and the part will exhibit a poorly balanced filling pattern.
Uniform wall thickness also helps reduce shrinkage. Different materials have different shrinkage rates. For instance, thick parts take longer time to cool than thin ones. As the part’s thickness increases, cooling time doubles. This relationship is due to the one-dimensional heat conduction equation, which shows that heat flows from the center of the part toward the cooling channel. However, this relationship does not hold for all types of plastics.
The general rule for maintaining uniform wall thickness in injection molded parts is that walls should be no thicker than 3mm. In some cases, thicker walls can be used, but they will significantly increase production time and detract from the part’s aesthetic appeal and functionality. Furthermore, the thickness of adjacent walls should be no thicker than 40-60% of each other.
The uniformity of wall thickness is critical to the overall quality and efficiency of the injection molding process. An uneven wall thickness can cause twisting, warping, cracking, and even collapse. A uniform wall thickness also reduces residual stress and shrinkage. Injection molded parts are more stable when the wall thickness is uniform.
An injection molded part with thick walls can be problematic, especially when the molded parts are shaped like a cube. A non-uniform wall thickness can result in problems and costly retooling. Fortunately, there are solutions to this problem. The first step is to understand the problem areas and take action.
Using 3D printing to fabricate molds
The use of 3D printed molds allows manufacturers to manufacture a wide range of injection molded parts. However, 3D-printed molds are not as strong as those made from metallic materials. This means that they do not withstand high temperatures, which can degrade them. As such, they are not suitable for projects that require smooth finishing. In order to reduce this risk, 3D-printed molds can be treated with ceramic coatings.
Using 3D printing to fabricate injection molds can help reduce costs and lead times, allowing manufacturers to bring their products to market faster. This process also has the advantage of being highly efficient, as molds made using 3D printing can be designed to last for many years.
The first step in fabricating an injection mold is to design a design. This design can be complex or simple, depending on the part. The design of the mold can be intricate. A simple example of a mold would be a red cup, with an interior and exterior. The interior portion would have a large cone of material protruding from the other side.
Injection molding is an effective way to produce thousands of parts. However, many engineering companies do not have access to expensive 3D printers. To solve this problem, companies should consider using outside suppliers. In addition to speeding up the manufacturing process, 3D printing can reduce the cost of sample parts.
Plastic injection molding still remains the most popular method for high volume production. However, this process requires a large up-front capital investment and takes a while to adapt. Its advantages include the ability to use multiple molds at once, minimal material wastage, and precision dosing. With an increasing number of materials available, 3D printing can be a smart option for companies looking to manufacture a variety of plastic parts.

Factors to Consider When Converting a Design to Injection Molding
When considering injection molding for your design, there are several things you should consider. These factors include design, material selection, process, and reliability. In addition, you should consider the price of each part. The average cost per injection molded part is between $1 and $5. If you want to reduce your costs and improve your production cycle, look into converting your design to injection molding.
Design considerations for injection molded parts
Injection molded parts must meet certain design considerations to ensure quality and precision. Design considerations include proper material choice, process control, and tool design. In addition, designers must consider the tolerance ranges for the parts to be produced. These tolerances will differ from molder to molder, and designers should discuss their specific needs with their molders before they begin production. Designers must also consider possible revisions to the mold, such as making the part more or less tighter.
When designing injection molded parts, the designer should consider the thickness of each wall. This will minimize stresses that may arise due to uneven wall thickness. Parts with uneven wall thickness can develop sink marks, voids, and molded-in stresses. This can result in longer production time and increased cost. Moreover, irregular wall thickness can restrict material flow. To minimize these problems, designers should make the transitions between the different thicknesses smooth.
Another important design consideration is the use of bosses in injection molded parts. Bosses are typically used as points of assembly and attachment in injection molded parts. Bosses are cylindrical projections with holes for threaded inserts and other fastening hardware. Injection molded parts with bosses are generally able to accommodate multiple threaded inserts without stripping. These inserts are also durable and enable several cycles of assembly.
The thickness of the walls is another important consideration when designing injection molded parts. The thickness of walls will determine many key characteristics of the part. Careful consideration of this feature will prevent expensive mold modifications and delays. The nominal wall thickness should be determined based on the functional requirements of the part. Likewise, the minimum wall thickness should be set based on acceptable stress. If the walls are too thin, air will collect between them and compromise the functional performance of the part.
Material selection
Selecting the right material for your injection molded parts is an important part of the process. While there are many options, there are also many factors to consider. For instance, what kind of end product are you producing? Whether it’s a consumer part for your home or a complex part for the aerospace industry, you’ll need the right material for the job.
There are literally hundreds or thousands of types of plastic materials available for injection molding. One of the most common types is ABS, a polymer that has a high degree of structural strength and low cost. Another popular choice is polycarbonate, which offers excellent heat resistance and transparency. Alternatively, you can opt for Ultem, a high performance plastic that’s commonly used in medical and aerospace applications.
The process of designing plastic products involves a combination of art and science. The goal of this process is to create a high-quality product that meets the expectations of consumers. By doing this, you’ll reduce production costs and increase profits. It’s not an easy process, but it’s well worth the effort.
Injection molding is an efficient and versatile method of manufacturing medical devices. It can be done in high volumes and with high flexibility. In addition to this, it also offers a broad range of materials. This is important when your parts need to be made of different materials with unique physical properties. For example, if you’re producing toys, you’ll want to use Acrylonitrile Butadiene Styrene (ABS). ABS is also a great option for medical applications because it can withstand the high temperatures and pressures of medical environments.
When choosing plastic injection molding materials, keep in mind the weight and stiffness of the material. Some applications require hard plastics, while others require softer materials. In addition, the material’s flexibility will determine how much you can bend it.
Process
Injection molding is a process in which plastic parts are formed by pressing melt into a mold. The process takes place in two stages. During the first step, the material is injected and heated, while the second stage is when the mold is opened and the part ejected. The part is then finished and ready for use.
The material used in injection molding is made from a variety of polymers. Common polymers include nylon, elastomers, and thermoplastics. Since 1995, the number of materials used in injection molding has increased by 750 percent. Some materials are newly developed while others are alloys of previously-developed materials. The selection of material primarily depends on the strength and function required by the final part. Also, the cost of the material is a critical factor.
The design of custom components for the molding process should be carried out by a skilled industrial designer. There are a number of design guidelines for plastic parts, which should be followed carefully to achieve high quality and dimensional accuracy. Failure to follow these guidelines can lead to undesirable results. Therefore, it is crucial to specify specific requirements for the parts before the process begins.
The process is reliable and highly repeatable, making it ideal for large-scale production. Injection molding also allows for the creation of multi-cavity injection mold parts, which can create several parts in one cycle. Other advantages of the injection molding process include low labor costs, minimal scrap losses, and low post-mold finishing costs.
Before beginning the full production run, technicians perform a trial run. In this test, they insert a small shot weight in the mould. Then, they apply a small holding pressure and increase the holding time until the gate freezes. Then, they weigh the part to check if it is right.
Reliability
Injection-molded parts are subject to a variety of defects. One of the most common is unwanted deformation. This may happen when the temperature of the mold is too high or there is not enough plastic injected into the mold. Another problem is millidiopter range distortion. This distortion is invisible to the naked eye, and cannot be detected by manual inspection. Regardless of the cause, preventing unwanted deformations is critical for the long-term performance of the part.
The process of creating a custom mould for a plastic component requires great skill. Creating a mould that is perfectly suited to the product is important, because a good mould is crucial in avoiding potential defects. Traditionally, this process relied on the skill of a toolmaker and trial-and-error methods. This slows down the process and increases the cost of production.
Another factor contributing to injection molded parts’ reliability is the high level of repeatability. Injection molding is ideal for high volume production, because parts are easily re-molded. However, the process can be prone to failure if there is no quality control. While most injection-molded parts will last for a long time, parts that are prone to wear will eventually fail.
Besides high level of consistency and reliability, injection-molded parts are also eco-friendly. Unlike other manufacturing methods, the injection molding process produces little to no waste. Much of the plastic left behind in the process can be recycled, making it a green alternative. Another benefit of this manufacturing method is automation, which helps reduce production costs. Overall, injection molding is a highly reliable and consistent product.
Injection molding requires precise measurements and a 3-D model. It is also important to check for wall uniformity and draft angles. Properly-designed parts can avoid deformations. If the wall thickness is too low, support ribs can be used. Proper draft angles are important to ensure that the part can be removed easily from the mold.
Cost
The cost of injection molded parts depends on many factors, including the complexity of the part and the mold design. Simpler designs, fewer CAD steps and simpler processes can help companies minimize costs. Another factor that affects the cost of injection molded parts is the geometry of the part. In general, complex geometries require more design work and tooling time. Additionally, thicker walls require more material than thin ones, which raises the cost of the part.
The amount of plastic used in the mold is also a key factor. Injection molding requires large quantities of material, so parts that are larger will require a larger mold. Larger parts are also more complex, so these require more detailed molds. A mold maker will be able to advise you on how to design your part to cut down on costs.
The next major factor affecting the cost of injection molded parts is the material of the mold. Most injection molds are made of steel, but the type and grade of steel used is important. Additionally, tight tolerances require molds with virtually wear-free interior cavities. Hence, higher-grade steel is required.
Another factor affecting the cost of injection molded parts is the price of mold tools. Depending on the size and complexity of the part, the cost of molding tools can vary from $10,000 to several hundred thousand dollars. Injection molding tooling is an integral part of the entire process and can add up to a significant portion of the overall cost of the part.
Draft angles are another factor that affects the cost of injection molded parts. A draft is an important design element as it allows for easy part separation and removal from the mold. Without a draft, it would be very difficult to remove a part after injection.

Design Considerations for Injection Molded Parts
There are many factors to consider when designing a component for injection molding. These include design factors, materials, overhangs, and process. Understanding these factors will make it easier to choose the right part for the application. In this article, we’ll go over several of the most common design considerations.
Design factors
To get the best results from your injection molded parts, you must ensure that they meet certain design factors. These factors can help you achieve consistent parts and reduce cost. These guidelines can also help you to avoid common defects. One of the most common defects is warping, which is caused by the unintended warping of the part as it cools.
When designing injection molded parts, the draft angle is critical. Increasing the draft angle allows the part to emerge cleanly from the mold and reduces stress concentration. This can improve the part’s function and speed up the production process. In addition, it ensures a uniform surface finish. Incorrect draft angles can result in parts that are not functional and can cost you money. If your product team doesn’t pay attention to these design factors, they could end up destroying expensive molds and producing a high number of rejects.
Ribs are another design factor that should be taken into consideration. Rib height should be less than three times the thickness of the part’s wall. This will prevent sink marks and minimize the chances of the ribs sticking inside the mold.
Materials
There are many options when it comes to materials for injection molded parts. Choosing the right material will affect how well it performs in your particular application. If you need a large part to be flexible and sturdy, then a plastic with good flow properties will work best. Injection molded plastics come in a variety of different resins. Choose the one that best meets your application’s needs, considering its main functionality and the desired appearance. You may also want to choose a material that is UV resistant, heat resistant, flexible, and food safe.
Polymers that are suitable for injection molding include polycarbonate and polypropylene. These materials are flexible and strong, and can be used to create parts with high-level details. These materials are also lightweight and inexpensive. Despite being flexible, they are not suitable for high-stress applications.
During the molding process, the injected material must be cooled, otherwise it will expand again. This is why you need to keep the temperature of the mould at 80 degrees Celsius or less.
Process
Injection molding is the process of creating plastic parts. The plastic is melted in a mold and then forced to cool. It then solidifies into the desired shape. During the cooling process, the plastic can shrink, so it is important to pack the material tightly in the mold to prevent visible shrinkage. When the mold is completed, it cannot be opened until the required cooling time has passed. This time can be estimated based on the thermodynamic properties of plastic and the maximum wall thickness of the part.
The mold must be precisely designed and tested. The process can be repeated many times, which makes it ideal for mass production. It is also one of the fastest ways to scale production. The more parts a mold can produce, the lower its cost per piece. This is one of the benefits of injection molding.
Injection molding parts are used for many industries, including appliances, electronics, packaging, and medical devices. They can be made to have complicated shapes.
Overhangs
Overhangs are areas of extra material that surround the surface of an injection molded part. This extra material is typically made of inexpensive material that is edged or glued on the part’s surface. The overhang material can be easily separated from the blank using a simple cutting process.
The amount of material needed for an overhang is dependent on the shape of the part and the amount of surface area. Generally, an overhang is less than 15 percent of the cost of the part. Usually, the material used should be able to fulfill the overhang’s function and differentiate it from the material in the form flachen area.
Overhangs on injection molded parts should be avoided because they may cause the design to become unstable. To avoid this problem, consider designing your part so that the sides and edges are parallel to one another. This will help ensure that the part will be free of undercuts and overhangs.
Overhangs on injection molded parts can be avoided by ensuring that the parts are designed with tolerances in mind. For example, an overhang in an injection molded part can cause a mold to have an overhang that is too small for the machine. This can cause problems in the manufacturing process, and it can result in a costly mold.
Cost
Injection molding costs can vary depending on the complexity of the part, the size and the type of plastic. Parts with complex geometries may require additional design work and tooling. Larger parts can also cost more than small ones. The amount of time spent designing and producing them is also important.
To reduce the cost of injection molding, a manufacturer must consider two major factors: tooling and the material used. The plastic used for injection molding has several different properties, which will impact the part price. For instance, plastics with a lot of glass fibers will reduce the amount of time necessary to repair the mold. Another factor to consider is the thermal properties of the material.
The next major factor in the cost of injection molded parts is the material of the injection mold. While most of these molds are made of steel, the type and grade of steel used is important. Injection molds are also required to have nearly wear-free interior cavities. This is necessary to maintain tight tolerances.
Another factor that contributes to the cost of injection molded parts is the cost of bulk material. This material costs money and requires expensive electricity to process. Typically, the more parts you produce, the lower the cost per pound. Storage of bulk material is also a significant expense. Therefore, a quicker cycle time will reduce storage costs.
Reliability
While manufacturing involves some degree of variation, the variation should be within acceptable limits. This is essential if you want to produce high-quality, dimensionally stable parts. A reliable manufacturing process involves precise control over mold tooling and part design. It also requires repeatability in both quality and production processes.
A reliable injection molding process also focuses on detecting defects early in the production process. Invisible hazards, such as air pockets, mold materials compromised by overheating, and more, can lead to failure. These defects will most likely not be discovered by simple visual inspection and may not come to light until after warranty claims are filed from the field. By finding the defects in the early stages, manufacturers can maximize productivity and reduce costs by minimizing the number of replacement parts needed.
The process of building a custom mould for plastic components is highly skilled. A perfect mould will eliminate potential defects and ensure that the production process is reliable. Traditionally, this process relied on trial and error, which added time and money to the production process.
Design for manufacturability
When designing injection molded parts, it is imperative to keep in mind their manufacturability. Injection molding allows for complex geometries and multiple functions to be combined into a single part. For example, a hinged part can have a single mold that can produce two different halves. This also decreases the overall volume of the part.
Injection molded parts do not typically undergo post-processing. However, the mold itself can be finished to various degrees. If the mold is rough, it can cause friction during the ejection process and require a larger draft angle. Detailed finishing procedures are outlined by the Society of Plastics Industry.
The process of designing injection molds is very exacting. Any errors in the mold design can lead to out-of-spec parts and costly repair. Therefore, the process of Design for Manufacturability (DFM) validation is a key step early in the injection molding process. Fictiv’s DFM feedback process can identify design challenges and provide early feedback to minimize lead times and improve quality.
The surface of an injection molded part can develop sink marks, which occur when the material has not fully solidified when it is ejected from the mold. Parts with thick walls or ribs are more prone to sinking. Another common defect in plastic injection molding is drag marks, which occur when walls scrape against one another during ejection. In addition to sink marks, parts with holes or exposed edges can form knit lines.

Design Considerations for Injection Molded Parts
There are many factors to consider when designing a component for injection molding. These include design factors, materials, overhangs, and process. Understanding these factors will make it easier to choose the right part for the application. In this article, we’ll go over several of the most common design considerations.
Design factors
To get the best results from your injection molded parts, you must ensure that they meet certain design factors. These factors can help you achieve consistent parts and reduce cost. These guidelines can also help you to avoid common defects. One of the most common defects is warping, which is caused by the unintended warping of the part as it cools.
When designing injection molded parts, the draft angle is critical. Increasing the draft angle allows the part to emerge cleanly from the mold and reduces stress concentration. This can improve the part’s function and speed up the production process. In addition, it ensures a uniform surface finish. Incorrect draft angles can result in parts that are not functional and can cost you money. If your product team doesn’t pay attention to these design factors, they could end up destroying expensive molds and producing a high number of rejects.
Ribs are another design factor that should be taken into consideration. Rib height should be less than three times the thickness of the part’s wall. This will prevent sink marks and minimize the chances of the ribs sticking inside the mold.
Materials
There are many options when it comes to materials for injection molded parts. Choosing the right material will affect how well it performs in your particular application. If you need a large part to be flexible and sturdy, then a plastic with good flow properties will work best. Injection molded plastics come in a variety of different resins. Choose the one that best meets your application’s needs, considering its main functionality and the desired appearance. You may also want to choose a material that is UV resistant, heat resistant, flexible, and food safe.
Polymers that are suitable for injection molding include polycarbonate and polypropylene. These materials are flexible and strong, and can be used to create parts with high-level details. These materials are also lightweight and inexpensive. Despite being flexible, they are not suitable for high-stress applications.
During the molding process, the injected material must be cooled, otherwise it will expand again. This is why you need to keep the temperature of the mould at 80 degrees Celsius or less.
Process
Injection molding is the process of creating plastic parts. The plastic is melted in a mold and then forced to cool. It then solidifies into the desired shape. During the cooling process, the plastic can shrink, so it is important to pack the material tightly in the mold to prevent visible shrinkage. When the mold is completed, it cannot be opened until the required cooling time has passed. This time can be estimated based on the thermodynamic properties of plastic and the maximum wall thickness of the part.
The mold must be precisely designed and tested. The process can be repeated many times, which makes it ideal for mass production. It is also one of the fastest ways to scale production. The more parts a mold can produce, the lower its cost per piece. This is one of the benefits of injection molding.
Injection molding parts are used for many industries, including appliances, electronics, packaging, and medical devices. They can be made to have complicated shapes.
Overhangs
Overhangs are areas of extra material that surround the surface of an injection molded part. This extra material is typically made of inexpensive material that is edged or glued on the part’s surface. The overhang material can be easily separated from the blank using a simple cutting process.
The amount of material needed for an overhang is dependent on the shape of the part and the amount of surface area. Generally, an overhang is less than 15 percent of the cost of the part. Usually, the material used should be able to fulfill the overhang’s function and differentiate it from the material in the form flachen area.
Overhangs on injection molded parts should be avoided because they may cause the design to become unstable. To avoid this problem, consider designing your part so that the sides and edges are parallel to one another. This will help ensure that the part will be free of undercuts and overhangs.
Overhangs on injection molded parts can be avoided by ensuring that the parts are designed with tolerances in mind. For example, an overhang in an injection molded part can cause a mold to have an overhang that is too small for the machine. This can cause problems in the manufacturing process, and it can result in a costly mold.
Cost
Injection molding costs can vary depending on the complexity of the part, the size and the type of plastic. Parts with complex geometries may require additional design work and tooling. Larger parts can also cost more than small ones. The amount of time spent designing and producing them is also important.
To reduce the cost of injection molding, a manufacturer must consider two major factors: tooling and the material used. The plastic used for injection molding has several different properties, which will impact the part price. For instance, plastics with a lot of glass fibers will reduce the amount of time necessary to repair the mold. Another factor to consider is the thermal properties of the material.
The next major factor in the cost of injection molded parts is the material of the injection mold. While most of these molds are made of steel, the type and grade of steel used is important. Injection molds are also required to have nearly wear-free interior cavities. This is necessary to maintain tight tolerances.
Another factor that contributes to the cost of injection molded parts is the cost of bulk material. This material costs money and requires expensive electricity to process. Typically, the more parts you produce, the lower the cost per pound. Storage of bulk material is also a significant expense. Therefore, a quicker cycle time will reduce storage costs.
Reliability
While manufacturing involves some degree of variation, the variation should be within acceptable limits. This is essential if you want to produce high-quality, dimensionally stable parts. A reliable manufacturing process involves precise control over mold tooling and part design. It also requires repeatability in both quality and production processes.
A reliable injection molding process also focuses on detecting defects early in the production process. Invisible hazards, such as air pockets, mold materials compromised by overheating, and more, can lead to failure. These defects will most likely not be discovered by simple visual inspection and may not come to light until after warranty claims are filed from the field. By finding the defects in the early stages, manufacturers can maximize productivity and reduce costs by minimizing the number of replacement parts needed.
The process of building a custom mould for plastic components is highly skilled. A perfect mould will eliminate potential defects and ensure that the production process is reliable. Traditionally, this process relied on trial and error, which added time and money to the production process.
Design for manufacturability
When designing injection molded parts, it is imperative to keep in mind their manufacturability. Injection molding allows for complex geometries and multiple functions to be combined into a single part. For example, a hinged part can have a single mold that can produce two different halves. This also decreases the overall volume of the part.
Injection molded parts do not typically undergo post-processing. However, the mold itself can be finished to various degrees. If the mold is rough, it can cause friction during the ejection process and require a larger draft angle. Detailed finishing procedures are outlined by the Society of Plastics Industry.
The process of designing injection molds is very exacting. Any errors in the mold design can lead to out-of-spec parts and costly repair. Therefore, the process of Design for Manufacturability (DFM) validation is a key step early in the injection molding process. Fictiv’s DFM feedback process can identify design challenges and provide early feedback to minimize lead times and improve quality.
The surface of an injection molded part can develop sink marks, which occur when the material has not fully solidified when it is ejected from the mold. Parts with thick walls or ribs are more prone to sinking. Another common defect in plastic injection molding is drag marks, which occur when walls scrape against one another during ejection. In addition to sink marks, parts with holes or exposed edges can form knit lines.
