What are the Design Considerations for Low-Volume Injection Molding Plastic Parts?

When it comes to plastic parts, there are a few design considerations that need to be taken into account. This is especially true for low-volume plastic parts. Here, we will explore what some of those design considerations are and how they can impact your project.

1.Choose the right material.

The first thing to consider when designing a low-volume plastic part is the material used. There are many different types of plastics available, each with its unique characteristics. It’s crucial to select a material that will be durable enough to withstand the intended use of the part.

There are a few key things to consider when choosing a suitable material for your next project. First, think about what properties are essential to the function of your part. For example, if you need a flexible piece, then you’ll want to choose a material with good flexibility properties. If you need a strong and rigid part, you’ll want to select a material with high strength and stiffness properties.

Next, consider the manufacturability of the material. Some materials are simply more challenging to work with than others. Finally, don’t forget about the cost. In many cases, the chosen material will have a direct impact on the cost of manufacturing your parts. Be sure to weigh all these factors carefully before making your final decision.

2.Scale the wall thickness in both directions.

One critical consideration when designing a low-volume plastic part is wall thickness. This factor will determine its strength, stiffness, and overall durability. If the wall thickness is too thin, the part may be too fragile and susceptible to breakage. If the wall thickness is too thick, the part may be too cumbersome.

To strike the right balance, it is essential to scale the wall thickness in both directions. It means making the walls thicker in some areas and thinner in others. For example, you might want to make the walls thicker near joints or connections, as these are typically weaker points. In addition, you can also opt for walls thinner in less stress or strain areas.

By scaling the wall thickness in both directions, you can create a low-volume plastic part that is strong and durable and meet all your project needs.

3.Use Radii to solve corner problems.

Regarding plastic parts, one of the key design considerations is how to deal with corners. It is because sharp corners are more likely to cause stress and breakage.

One way to solve this problem is to use radii instead of sharp corners. It means that the corners are rounded off, which helps to distribute stress more evenly and reduces the chance of breakage.

Another advantage of using radii is that it can help improve the aesthetics of the part and make it easier to clean and maintain. It will also ensure a more substantial product and improved moldability.

4.Use the Draft Angle to Enable Easier Ejection of the Part.

The ease of ejection of a plastic part from the mold is something you can not overlook. This is especially important in low-volume production, where manually removing each part from the mold can be time-consuming and tedious.

One way to facilitate easier ejection is to use a draft angle on the part. This is an angled surface that allows the part to be released from the mold more easily. The draft angle also helps to prevent sticking and warping, which can occur when parts are removed from the mold too forcefully.

Another consideration for ejection is the material used for the part. Some materials are more prone to sticking than others, making them more challenging to remove from the mold. If possible, choose a material that will not stick to the mold or require a lot of force to eject.

Finally, consider the geometry of the part itself. Parts with complex geometries can be more challenging to eject than those with simpler shapes. If the ejection is likely to be an issue, simplify the part’s geometry as much as possible.

5.Go for a Multi-Cavity Mold when designing custom low-volume plastic parts.

Multi-cavity molds can offer advantages over single-cavity molds, such as increased production efficiency and lower unit costs. With multiple cavities, each cycle of the molding process produces multiple parts, which leads to a significant decrease in overall production time. Additionally, multi-cavity molds often have shorter cycle times than single-cavity molds due to their increased cavitation.

However, they also come with some unique challenges that must be considered before making a decision. One of the biggest challenges is ensuring that each cavity is identical. If there are any differences in the cavities, it can lead to inconsistencies in the final product. Multi-cavity molds often require more intricate designs and tighter tolerances than single-cavity molds due to the need for more excellent symmetry between the cavities.

Another consideration is cost. Multi-cavity molds tend to be more expensive than single-cavity molds due to their increased complexity. However, they can offer significant cost savings in terms of production time and unit cost if designed correctly.


Custom low-volume plastic parts are a great way to get the parts you need without ordering a large quantity. The process is simple and easy to follow, and the results are usually high-quality and accurate.

If you are fascinated with the advantages of low-volume plastic parts and are more inclining toward them for your business, consider working with a professional and experienced manufacturer. A professional approach helps you get the needed parts and have more control over the manufacturing process. Plus, working with the right manufacturer can often be more cost-effective than working with a mass production company
