Job description

Employer: Core Molding Technologies, Inc.

Geographic Location: Columbus, OH

Position: Molding Engineer

Duties: Lead and support compression molding operations within manufacturing facility driving process excellence, optimizing tooling and fixtures, and ensuring high standards of quality, efficiency, and continuous improvement. Provide engineering support for compression molding operations, including tooling, fixtures, process development, and work instructions for SMC, RTM, RIM, and injection molding. Operate and troubleshoot high-tonnage compression presses (250–4,500 tons), addressing failures such as overheating, pressure loss, servo valve faults, and safety alarms. Lead mold set-up and changeovers for dies up to 80,000 tons and implement SMED projects to reduce downtime for coated and non-coated SMC and RTM pieces. Drive process optimization, scrap reduction, and quality improvement initiatives across molding lines. Troubleshoot complex molding defects including porosity, blisters, non-fills, cracking, under-curing, and contamination using root cause analysis and hydraulic schematics.
