Key Responsibilities Production Startups:

Perform mold setups, process startups, and validations for new and existing production runs while ensuring first-piece quality approval.

Process Optimization:

Monitor and adjust molding parameters including temperature, pressure, injection speed, and flow to maintain process stability and product quality.

Cycle Time Management:

Audit active production jobs to ensure cycle times meet or exceed established standards; identify and resolve inefficiencies as needed.

Scientific Molding:

Use decoupling techniques (RJG or similar principles) to establish robust process windows that minimize scrap.

Troubleshooting:

Quickly diagnose and resolve molding defects such as flash, short shots, splay, sink, and warpage to maintain uninterrupted production.

Continuous Improvement:

Recommend and implement process, tooling, or equipment improvements that enhance productivity, repeatability, safety, and overall operational efficiency.
