What are the key responsibilities of a Plastics Engineer?

•Design and develop plastic parts and components using CAD and CAE tools for manufacturability and performance
•Specify materials, additives, and resins based on mechanical, thermal, and chemical requirements
•Optimize injection molding, extrusion, blow molding, and thermoforming processes to improve yield and reduce cycle time
•Conduct failure analysis, root cause investigations, and implement corrective/preventive actions
•Develop and validate tooling, mold flow analyses, and process control plans
•Implement cost-reduction initiatives through material substitution, scrap reduction, and process optimization
•Manage product validation, PPAP/IQ/OQ/PQ documentation, and regulatory/compliance testing
•Collaborate with cross-functional teams including R&D, quality, suppliers, and manufacturing to scale products
•Establish and monitor quality metrics (CPK, SPC) and lead continuous improvement projects (Lean, Six Sigma)
•Provide technical support to suppliers and manufacturing during ramp-up and production phases
