Improving Profitability in Injection Moulding - May 2017

23rd - 24th May 2017

Shawbury Shropshire, UK

Price: £660

Course duration: 2 days


Purchasing a mould is a high risk capital investment for any company. Managing a tooling project or procuring a tool requires an understanding of how moulds are made and is critical to getting-it-right-first time. An awareness of the technicalities of mould design will also improve communications between product designers and mould designers and reduce costly errors and delays.

This course will give attendees the skills and knowledge needed to build safeguards into mould procurement and tooling projects and to improve component design to reduce moulding costs and improve product quality.

Course Objectives:

The objective of this course is to give mould procurement and supply chain management personnel, along with product designers a thorough appreciation of mould manufacture and manufacturing terminology, how mould design can influence costs and product quality (and how component design can add to moulding costs). 

Attendees will be better placed to evaluate the capability of the mould maker before placing an order and to build safeguards into tooling projects. Product Designers will learn how component design can effect mould cost, lead times and mould maintenance.

Attendees will Learn:

  • 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
