Who Should Attend

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.

Learning Outcomes

Upon completion, students will be able to:

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

Assessment & Accreditation

This programme is a QQI component (minor) award, certified at Level 5 on the national framework of qualifications – see www.nfq.ie  and is an elective component of major award  5M3080 – Plastics Injection Moulding.

The assessment is comprised of a written exam on the last day of the course plus an assignment that is due to be submitted 4- 6 weeks after the end of the course. An exact date and submission link is given to each course participant, with full guidance and support given by the Trainer. Trainees generally complete this assignment in their own time, over the period allocated.
