Programme overview

Introduction to Injection Mould Design

The program assumes no prior knowledge or ability to design an injection mould tool. The program covers the basics of plastic injection mould design and is intended to provide a platform for those wishing to undertake mould design. The course will assist those engaged in the art of machine setting with a greater understanding of the influence the mould tool has on part quality, output volume and process efficiency. This course is an essential foundation for setters, part designers and mould designers working or wishing to work in the injection moulding industry.

Follow on courses recommended:

  • Plastic Part Design
  • Plastic Materials Selection
  • Injection Moulding

Learning outcomes

Upon completion, someone having undertaken the course will be able to:

  1. Understand the design and function of a 2-Plate mould.
  2. Understand the design and function of a 3 – Plate mould.
  3. Be able to design a basic mould feed system.
  4. Be able to select a gate to production requirement.
  5. Be able to design a mould cooling system.
  6.  Be able to design a mould ejection system.
  7. Be able to combine LOI3-6 into a mould design.
  8. Be able to undertake a basic appraisal of a new injection moulded component.
  9. Be able to differentiate between a part design fault, a mould design fault, a material fault and a processing defect.

Who is the course for

Injection Moulding Technicians, Engineers, and Management who have a responsibility for ordering, modifying or replacing injection moulds will gain most benefit from this course. A better understanding of mould design theory will greatly assist in obtaining optimised moulds and reducing mould commissioning times.
