Day-to-Day Responsibilities
Design plastic parts, containers and packaging for strength, weight, appearance and cost.
Choose the right polymer for each job, such as polyethylene (PE), polypropylene (PP), PET, PVC, ABS or polycarbonate, based on heat, chemical and impact resistance.
Design moulds and dies for processes such as injection moulding, blow moulding and extrusion.
Set and fine-tune process conditions such as temperature, pressure and cycle time to get consistent output.
Test samples for strength, durability and heat resistance, and find the cause of defects such as warping or sink marks.
Work with production, quality and suppliers to take a product from prototype to full-scale manufacture.
Review material choices and design for recycling, including the use of recycled content, to reduce waste.
