A day in this role

You arrive to a well-organized cell, review the schedule, and plan a die, color, or material changeover. You lock out per Lockout/Tagout (LOTO), use a forklift or overhead crane to safely pull and set the mold, bring the injection molding press up, verify auxiliary equipment, and dial in parameters to hit cycle targets and part quality. When a defect shows, you troubleshoot, adjust, and document. Between runs, you validate the process, support a new mold trial with Engineering, and keep the area aligned to 5S standards.

• Set up and adjust injection molding machines, tooling, and auxiliaries for efficient production.
• Execute die, color, and material changeovers with complete documentation and team communication.
• Monitor and optimize molding processes to achieve consistent part quality and cycle efficiency.
