Core Responsibilities

Primary Functions

Skillfully set up and configure thermoforming machines for production runs, including the installation and adjustment of molds, dies, and tooling according to job specifications.
Operate heavy-duty, inline thermoforming equipment, carefully managing machine cycles, temperatures, and pressures to produce parts that meet precise quality requirements.
Continuously monitor machine performance during operation, observing gauges, dials, computer readouts, and other indicators to detect potential malfunctions or deviations from standards.
Conduct first-piece, in-process, and final quality inspections on products, utilizing precision measuring tools like calipers, micrometers, and gauges to verify dimensional accuracy.
Read and interpret complex work orders, blueprints, and production schedules to determine the correct setup, materials, and operational sequences for each job.
Make necessary adjustments to machine settings, such as heat, speed, and cycle times, to correct product defects and optimize production efficiency and material usage.
Perform routine preventative maintenance on machinery, including cleaning, lubricating, and inspecting parts to ensure optimal performance and minimize downtime.
Proactively troubleshoot and resolve operational issues and minor mechanical problems, effectively diagnosing the root cause to implement a lasting solution.
Handle and load large rolls or sheets of plastic material onto the machine, ensuring proper alignment and feed into the forming station.
Safely remove, stack, and package finished parts according to customer specifications, ensuring accurate counts and proper labeling for shipment.
Maintain detailed and accurate production logs, quality control records, and maintenance reports to ensure clear documentation and process traceability.
Adhere strictly to all company safety policies, procedures, and Lockout/Tagout (LOTO) protocols to maintain a safe and hazard-free work environment.
Identify and segregate non-conforming products or scrap material, documenting the cause of defects and communicating issues to the shift supervisor or quality department.
Utilize pallet jacks, forklifts, or other material handling equipment to move raw materials, finished goods, and tooling within the facility.
Collaborate with the maintenance team to diagnose and repair more complex mechanical or electrical issues that are beyond the scope of routine operator maintenance.
Perform and document tool and die changes efficiently and safely, ensuring all components are correctly installed and secured before starting a new production run.
Monitor the regrind system to ensure scrap plastic is being processed correctly and efficiently for reuse, contributing to our sustainability efforts.
Evaluate finished products for visual defects such as webbing, chill marks, tears, or contamination, taking corrective action as needed.
Maintain a high level of housekeeping in the work area, following 5S principles to ensure a clean, organized, and efficient production environment.
Communicate effectively with team members, supervisors, and quality personnel regarding production status, material needs, and any equipment or quality concerns.

Secondary Functions

Assist in the training and mentoring of new or less-experienced operators on machine functions, quality standards, and safety protocols.
Participate actively in continuous improvement teams and Kaizen events to help identify and implement process enhancements that boost productivity and reduce waste.
Support the inventory management process by helping with cycle counts of raw materials, packaging supplies, and finished goods.
Provide constructive feedback on tooling and machine performance to engineering and maintenance teams to aid in future design and process improvements.
