Polymer processing technicians produce polymer products to a specification. They work in a production facility - often on a large scale, using a range of machinery, control systems and engineering equipment. Products are made using continuous or in batch processes. Polymer processing technicians set up or configure equipment and tooling and prepare materials for processing. They run and monitor the process, adjusting parameters. They use unique technologies and processes such as extrusion, blow moulding, thermoforming, rotational moulding, injection moulding, internal mixing, and calendering.
