♻️🌱 Plastics Processing and Recycling - Rolbatch Academy - Webinars & Online Trainings

Real production defects in plastics processing can tell us far more than appearance alone. I am looking for photos of defects in pipes, profiles, sheets, films and other extruded plastic products. In return, I will provide a short technical comment: possible causes, areas to check first and directions for further analysis. The most interesting cases may inspire neutral examples in my upcoming book “Plastic Extrusion. Pipes • Profiles • Sheets • Films”. Submitted photos will not be published, and no company names, production sites, customers or production data will be disclosed.

Choosing a polymer family is only the first step. In real plastics processing, the decisive question is which specific raw material fits the product, tool, machine, throughput and quality requirements. PP, PE, ABS, PA, PC, POM, PET, PBT, PVC, PMMA, PPS or PEEK can behave very differently depending on flow, shrinkage, fillers, stabilisation and processing conditions. This article explains why material substitution should always be checked against the real process, not only against a data sheet, because the lowest price per kilogram can still create higher long-term production costs.
