A day in the life At 1:30 PM, you arrive on the production floor at Flexan’s Lincolnshire site, review the weekly plan, and prep for scheduled material changeovers on liquid injection molding equipment. You calibrate tooling, verify auxiliary systems, and log setup details so each molding cell starts clean and compliant. When a press throws an alarm, you dive into the electrical and mechanical signals—meter in hand (ohmmeter, voltmeter, megohmmeter)—to trace continuity, isolate root causes, and restore operation quickly. Between calls, you fine-tune parameters on molding machines and extruders, close out maintenance work orders, and share best practices with the next shift. You document adjustments, ensure cleanroom standards are met, and recommend improvements that reduce cost, improve quality, and prevent repeat failures. Safety, traceability, and teamwork anchor everything you do. What you’ll do Set up and perform material changeovers on liquid injection molding machines per the weekly schedule.
