Course overview

Injection moulding has a major impact on product quality, cost, and lead time.

This two-day classroom course gives you the technical insight and commercial understanding needed to optimise processes, reduce risk, and communicate more effectively with suppliers and colleagues.

You’ll leave with practical knowledge to improve productivity, troubleshoot issues, and add measurable value to your organisation.

Learning outcomes

By the end of this course you will be able to:
  • Understand the injection moulding process - gain clear insight into machine operation and cycle stages to identify and manage time and cost drivers.
  • Select and use materials more effectively - link polymer behaviour to part performance, ensuring better product quality and design outcomes.
  • Apply sound design principles - prevent shrinkage, flow, and thin-wall problems through informed design decisions early in development.
  • Evaluate and manage tooling - understand mould types, cooling systems, and cost factors that affect cycle times and part consistency.
  • Diagnose and solve moulding faults - recognise common processing issues and implement corrective actions to minimise downtime.
  • Explore process innovations - stay informed on emerging techniques such as in-mould decoration, gas-assisted, and water-assisted moulding.
  • Collaborate effectively with suppliers and teams - communicate technical requirements clearly during trials, sourcing, and production to ensure reliability and quality.

Course content

This course blends theory and practice to explain how materials, machines, and design choices influence moulding performance.

Process Theory
  • The injection moulding machine and moulding cycle explained
  • Advantages and disadvantages
Plastics Materials
  • Categories
  • Plastic flow – investigation and forces required
  • Processing effects on different polymers
Product Design
  • Limitations and sources of information
  • Polymer orientation
  • Shrinkage
  • Unique issues encountered in “Thin-Wall” design and manufacture
  • Flow simulation to analyse and optimise designs
Injection Moulds
  • Mould costs analysis
  • Mould terminology
  • Explanation of mould types and reasons for their choice
  • Mould cooling
  • Reducing cycle times and mould costs
Injection Moulding Faults
  • Cause and cures
  • Fundamental problems
  • Faults caused by inappropriate machine selection
  • Faults caused by poor mould and product design
Innovative Techniques
  • In-mould decoration
  • In-mould assembly
  • Gas injection/water injection
  • Advances in Injection compression moulding Exatec
Product Development using Outside Suppliers
  • Issues encountered when sourcing product
  • Investigative steps – what documents to request
  • Moulding process and machine choice issues

Who should attend

This course is ideal for anyone involved in the design, production, or specification of injection moulded components who wants to strengthen their technical understanding and decision-making.

  • Product designers and engineers – gain the insight needed to design parts that mould efficiently, perform reliably, and avoid costly rework.
  • Production and process managers or supervisors – improve process control, troubleshoot issues faster, and enhance productivity on the shop floor.
  • Quality and technical services personnel – build a deeper understanding of moulding variables to support root-cause analysis and consistent quality assurance.
  • Purchasers and sourcing professionals – learn what to ask for in tooling and trials to ensure suppliers meet performance, quality, and cost expectations.
  • Newcomers to injection moulding or those without formal training – develop a structured understanding of materials, processes, and design principles from the ground up.
