The Diploma in Design & Specification of Plastics was developed by Plastics NZ to meet the ongoing need to build skills in designing and developing products within the Industry. It is delivered by Industry Experts and topics include plastics and its performance, plastics design, and the chemistry of plastics and its properties. The diploma is a four part, seven day course held twice a year in Auckland.

  • Part 1 - An Introduction to Plastics Materials and Technologies
  • Part 2 - Introduction to Plastics Materials and their Performance
  • Part 3 - Important Aspects of Plastics Product Design
  • Part 4 - The Chemistry of Plastics and How it Affects Properties
