Course Description

This combined course is designed for toolmakers, apprentices, technicians, product designers, process engineers, and other plastics personnel desiring to acquire basic knowledge of product design and tooling technology. This course provides an overview of the design process for injection molded plastic parts. The emphasis is on concurrent engineering practices, which leads to elimination of barriers between various engineering groups, toolmakers, and manufacturers. The participant will learn about the importance of proper material selection, part design fundamentals, manufacturing (moldability) considerations, design for assembly, tooling considerations, rapid prototyping techniques, and testing.

Design fundamentals discussed are applicable to parts designed for all plastics processing techniques. In the tooling portion the emphasis is on various mold components, mold design principles, cooling, venting, draft considerations, shrinkage, mold polishing, and tool surface enhancement techniques. Topics such as use of simulation software to enhance mold design, how to improve productivity, reduce down time, and lower maintenance costs by optimizing tooling design will be covered in detail.

Course content:

  • Plastics materials and material selection process
  • Plastics material identification techniques
