Part Design for Injection Molding

Description du cours

RJG’s Part Design for Injection Molding course provides molders, tool makers, and design engineers with a common language and the universal knowledge required to successfully design and produce plastic injection molded components. Improving general knowledge of the steps required for part design reduces the risk of less than optimum tooling conditions, therefore minimizing exposure to injection molding non-conformities that do not meet the quality requirements of the customer.

Class topics address good manufacturing processes (GMP) for: plastic part design, fundamental material characteristics, basic tooling concepts, necessary processing characteristics, molding non-conformities, and tolerances. The course also discusses how part design and material selection affect the cost of tooling and piece price. During training, we utilize industry examples as reference, then dive into evaluating and improving designs. Attendees will work in groups to examine parts to identify where non-conformities will occur and methods to improve those risks.
