Core Responsibilities

Primary Functions

Execute the complete setup and operation of single or twin-screw extrusion lines in accordance with detailed production schedules, work instructions, and quality standards.
Perform complex machine changeovers, which includes the precise installation and alignment of dies, breaker plates, screen packs, and downstream equipment.
Continuously monitor critical process parameters such as melt temperature, screw speed, barrel pressure, and line speed, making proactive adjustments to ensure product conformity.
Conduct first-article and in-process quality control checks using precision measuring instruments like calipers, micrometers, and profilometers to verify dimensional accuracy and surface finish.
Systematically troubleshoot and resolve process deviations and equipment malfunctions in real-time to minimize production downtime and reduce scrap rates.
Interpret complex engineering blueprints, technical drawings, and manufacturing orders to accurately determine setup configurations and operational requirements.
Perform scheduled preventative maintenance tasks on extrusion machinery and auxiliary equipment, including thorough cleaning, lubrication, and inspection of critical components.
Diagnose and report mechanical, electrical, and hydraulic/pneumatic failures, and collaborate directly with the maintenance team to facilitate efficient repairs.
Manage the preparation and handling of raw materials, including the accurate blending of polymer resins, additives, and colorants, while ensuring strict lot traceability.
Diligently document all production data, process adjustments, quality inspection results, and downtime events in Manufacturing Execution Systems (MES) or production logbooks.
Champion a safety-first culture by strictly adhering to all safety protocols, especially Lockout/Tagout (LOTO) procedures during machine setup, maintenance, and cleaning.
Collaborate with the quality assurance department to investigate the root cause of product defects and participate in the implementation of robust corrective and preventive actions.
Actively participate in the training and mentoring of new operators and technicians on standard operating procedures (SOPs), safety guidelines, and quality control methods.
Proactively optimize machine settings and process parameters to enhance production efficiency, improve cycle times, reduce material waste, and elevate overall product quality.
Maintain a clean, organized, and safe work environment by consistently applying 5S principles and adhering to Good Manufacturing Practices (GMP).
Safely operate forklifts, overhead cranes, and other material handling equipment to transport raw materials, heavy tooling, and finished goods throughout the facility.
Calibrate, adjust, and maintain downstream equipment such as pullers, cutters, cooling tanks, winders, and saws to ensure they function in sync with the extruder.
Monitor and regulate cooling systems, including water troughs and air rings, to achieve consistent product crystallization, dimensional stability, and physical properties.
Perform meticulous tooling maintenance, including the expert cleaning, inspection, and polishing of dies and calibrators to prevent process defects and maximize tool lifespan.
Engage in continuous improvement projects and Kaizen events, providing valuable shop-floor insights and suggestions for process, safety, and quality enhancements.
Support the Research & Development and Engineering teams by assisting with the trial runs and process validation for new products, advanced materials, and emerging technologies.
Ensure that all finished products are properly packaged, correctly labeled with all required information, and staged efficiently for warehouse transfer or customer shipment.

Secondary Functions

Assist the maintenance department with more complex machine repairs, component rebuilds, and equipment installations during scheduled plant shutdowns.
Contribute to raw material inventory management by accurately tracking consumption, monitoring stock levels, and reporting any discrepancies.
Support the engineering and quality teams in the development, review, and revision of Standard Operating Procedures (SOPs) for the extrusion department.
Participate in facility-wide safety committee meetings and represent the department in continuous improvement initiatives and cross-functional team projects.
