It happens every day. You have begun searching for a part made of plastic that is needed in order to complete your idea for some type of design. You have been unsuccessful. You find yourself needing to find custom plastic injection molding services. There are two ways that you can go about having this done. You can design custom plastic parts yourself or you can have a shop that contains manufacturing engineers who specialize in building this parts to both build and design the molding piece so that it will meet your needs.

If you are not experienced in custom injection molding, you may want to have the part designed for you. This helps ensure that the part works the way you want it to. It’s critical to find an engineer that has experience in both engineering and design when you need a unique part created so that they can take your idea and bring it to life. Here are some important considerations to make when you are ordering these parts in order to ensure that the part functions how you imagined and works well for a long time.

Understand the Process

It’s critical that you understand the process. Injection molding is the technique utilized most often in order to create parts made of plastic. The first thing that happens is that the engineer will build the mold for the part. The mold is thus the template that every single successful part for that design is made from. Once the mold is made, the material is placed into the part and creates parts from this mold. Once the mold has been designed and made, the cost of creating this part goes down significantly.

How is the Part Going to Be Used?

If you want to make sure that you are using the right type of material for your part, the first thing you need to do is ensure that the manufacturer understands how you intend to use the part. There are over 40,000 different types of resin from which custom molds can be made available today. The more information that the engineer is provided with the better your part will be. The best course of action is to ensure that you have prepared some type of document that spells out in detail how you are going to use the part. You may even consider including a diagram of how this part is going to interact with other relevant parts. Written documentation provides less room for error than verbal explanations do.


The Concept of the Design

When you work with an engineer it comes with the added benefit of being able to access their experience in design. You best bet for effectively relaying your idea to the engineer is by speaking using use cases. Use cases are simply examples of how you intend to use the product. This will also help you walk through possible scenarios that you may want to use the piece in order to eliminate some of the trial and error involved in using a new part.
