Improving Profitability in Injection Moulding


This course will take place over one day, commencing at 9am and finishing at 4.30pm.

Reduce the cost of manufacture and increase profit margins

Injection moulding is a prolific, world-wide manufacturing process and has been around for more than half a   century. Why then are the majority of   businesses involved in the process considerably less profitable than they should be?

This course unravels the lengthy journey from concept to production of any plastic injection moulding. It demonstrates the need for ‘a strict regime of optimisation’ at every stage to maximise profitability and competitiveness.

Profitability in an injection moulding company comes from the application of sound knowledge in a formalised manner. There is no need to break new ground or to have a deep understanding of polymer science. The course examines every aspect of the manufacturing process and its contribution to profitability starting with product design, followed by polymer choice, design for manufacture analyses, tooling, processing and automation. Each part of the process is studied and explained supported by real world examples.

Myths and misunderstandings of the plastic injection moulding process will be dispelled and attendees will leave with substantial knowledge of how to improve their own operation’s profitability.

Course Objectives:

The primary objective of the course is to reduce the cost of manufacture in order to improve profitability. The process of developing a plastic injection moulded product is multifaceted and complex involving many decisions that directly impact on cost. The course studies the whole process identifying the cost implications and consequences of often unwitting decision making.

Attendees will Learn:

  • How the product design can dominate cost
  • How incorrect mould specifications can affect   productivity 
  • How incorrect polymer choice can increase scrap 
  • How Computer Aided Engineering can optimise   product design
  • How important mould cooling is
  • How effective training of process maximises   productivity
  • How Scientific Moulding techniques deliver more profit
  • How moulds are made, the effect on cost and timing
  • How moulds are constructed; the elements and terminology used
  • How component design can effect mould cost, lead time and mould maintenance
  • How mould design can influence product quality
  • The importance of mould cooling; gate and runner design etc
  • How to identify faults relating to mould design/manufacture
  • How to make mould design improvements
  • How to build safeguards into mould procurement
  • How to manage a tooling project
