Wall Thickness Guidelines For Injection Molded Parts

Posted by Molly Skiba on Aug 16, 2019

Aside from resin selection, wall thickness is one of the most important details to pay attention to when designing plastic injection molded parts. Determining the appropriate wall thickness is essential for optimizing the performance, appearance, moldability and cost of your part.  The prototyping stage gives you the opportunity to test your design out with different materials and also gives you the opportunity to tweak your part's dimensions before moving on to mass production.

We're here to get you through that stage as efficiently as possible. If you're new to designing parts for plastic injection molding, these guidelines will help you determine the appropriate wall thickness for your part. If you need more tips, don't forget to download our plastic prototyping toolbox and our injection mold classification guide!
