Designing plastic parts is a complex task involving many factors that address a list of requirements of the application. “How is the part to be used?” “How does it fit to other parts in the assembly?” “What loads will it experience in use?” In addition to functional and structural issues, processing issues play a large role in the design of an injection molded plastic part. How the molten plastic enters, fills, and cools within the cavity to form the part largely drives what form the features in that part must take.

Using our 8 years of injection molding manufacturing experience, Quickparts has created several resources to assist you in designing for this process. The Basics of Injection Molding Design is a guide outlining the basic rules to designing parts for injection molding that will make your parts stronger and easier to manufacture.

Design for Manufacturing Analysis is a free service offered with injection molding quotes where a report is generated by a Quickparts Production Engineer who reviews the feasibility of your part for manufacturing.  Click here for a sample report.

Injection Molding Glossary contains commonly used injection molding terms and their definitions.

These resources are free of charge and are all available in the Quickparts Learning Center.
