P4P4 — Senior Professionalhigh0.90approvedglobalv1

Designs and develops plastic and polymer components and the processes used to manufacture them. Distinct from broader Materials Engineering (metals, ceramics, composites) and from Tooling/Mold Design specialists in that this focus centers on polymer selection, plastics processing (injection molding, extrusion, thermoforming, blow molding), and Moldflow-driven validation of plastic part and process design from concept to production.
