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.
