🎯 Role Definition

The Extruder is a skilled manufacturing professional responsible for setting up, operating, troubleshooting, and maintaining extrusion equipment to produce polymer-based products to specification. This role focuses on controlling process parameters (temperature, screw speed, feed rate), performing die and tooling changes, conducting quality checks, performing routine maintenance, and collaborating with production, quality, and maintenance teams to meet production targets while ensuring safety and regulatory compliance. Ideal candidates have hands-on extrusion experience (single/twin-screw), strong mechanical aptitude, and a continuous improvement mindset.

Core Responsibilities

Primary Functions

  • Set up, calibrate and operate extrusion machinery (single-screw, twin-screw, co-rotating and counter-rotating systems) including feeders, gravimetric feeders, extruder barrels, screws, and downstream equipment to consistently produce parts within dimensional and material specifications.
  • Adjust and optimize process parameters — temperature zones, screw speed, feed rate, back pressure, and die gap — to achieve target throughput, melt homogeneity, and product quality while minimizing scrap and rework.
  • Perform die installation and precision die adjustments, including die trimming and gap setting, ensuring correct die alignment and part geometry for specified tolerances and surface finish.
  • Monitor real-time process data and control systems (PLC/HMI) for alarms, cycles, and trends; respond to deviations by diagnosing root causes and implementing corrective actions to avoid downtime.
  • Conduct first-piece inspections, in-process quality checks, and final product verification using calipers, micrometers, gauges, and visual inspection criteria to ensure compliance with quality control plans and customer specifications.
  • Troubleshoot mechanical, hydraulic and electrical issues on extrusion lines — including screw wear, barrel scoring, motor issues, drives, and heater zone failures — and coordinate rapid escalation to maintenance when required.
  • Execute preventive and routine maintenance tasks such as bearing checks, screw removal and inspection, heater band replacement, gearbox oil checks, and lubrication to extend equipment life and maintain reliable production.
  • Manage raw material handling and preparation: verify resin type, moisture levels, drying schedules, colorant and additive batching, and proper loading of hoppers and gravimetric feeders to prevent material-related defects.
  • Lead setup and changeover activities for new production runs including cleaning, purging, tooling changes, and documentation to minimize changeover time and maintain schedule adherence.
  • Maintain accurate production records, shift logs, batch records, material lot traceability, scrap reports, and maintenance requests in the Manufacturing Execution System (MES) or paper-based systems to support traceability and continuous improvement.
  • Enforce strict adherence to safety, environmental, and regulatory requirements (OSHA, REACH, RoHS as applicable) by following lockout/tagout, confined space, PPE, machine guarding, and hot-work procedures on the extrusion line.
  • Implement and support quality programs such as Statistical Process Control (SPC), Failure Mode and Effects Analysis (FMEA), and corrective action plans to identify variability and drive defect reduction.
  • Collaborate with process engineers and R&D to scale up new extrusion formulations, compounds, and products from pilot trials to full production, providing feedback on manufacturability and process windows.
  • Train and mentor junior operators on extrusion best practices, Standard Operating Procedures (SOPs), safety protocols, and quality inspection techniques to build a skilled, multi-functional team.
  • Participate in root cause analysis for recurring process issues, using 5-Why, fishbone diagrams, and data-driven investigation methods, and implement corrective and preventive actions to eliminate systemic problems.
  • Optimize material throughput and line efficiency by recommending and implementing process improvements, line balancing, screw design changes, and downstream equipment upgrades to increase OEE.
  • Conduct in-line and off-line sampling for laboratory analysis (melt flow index, density, tensile testing, colorimetry) and coordinate with quality laboratory staff for timely disposition decisions.
  • Manage purge and cleaning procedures for color changes or material grades, minimizing contamination and material waste while ensuring rapid product changeover readiness.
  • Coordinate with maintenance and electrical technicians to schedule downtime for major repairs and capital projects, prioritizing production needs while assuring safe execution of work.
  • Ensure compliance with company documentation practices — updating work instructions, machine logs, and preventive maintenance checklists — to maintain consistent operations and audit readiness.
  • Oversee downstream equipment like pullers, calibrators, cutters, water tanks, winders and take-up systems, ensuring synchronization and tension control for consistent final product geometry and winding quality.
  • Maintain inventory control of critical spare parts (screws, barrels, heater bands, thermocouples, seals) and consumables to reduce mean time to repair and support reliable production flow.
  • Support continuous improvement initiatives (Kaizen events, Lean manufacturing, 5S) on the extrusion floor, recommending layout changes, waste reduction strategies, and standard work improvements to increase throughput and reduce cost.
  • Communicate effectively with production planning, quality, supply chain and shipping teams regarding production status, material shortages, quality holds and shipment readiness to meet customer delivery requirements.
  • Participate in new product introduction (NPI) meetings, provide build-time estimates, and validate process capability for new extrusion products and custom orders.

Secondary Functions

  • Assist with housekeeping, 5S floor activities, and proper material storage to maintain a safe and efficient work environment.
  • Support cross-training efforts by shadowing and mentoring colleagues on adjacent equipment or processes as workloads require.
  • Help prepare and pack finished product for shipping when line duties permit, ensuring correct labeling and documentation.
  • Provide shift turnover briefings and handoff notes to incoming operators to maintain continuity and transfer process knowledge.
  • Participate in safety observations, hazard assessments, and corrective action follow-up to continuously improve workplace safety culture.
  • Engage in scheduled training programs to stay current on extrusion technologies, control systems, and regulatory changes.
  • Support ad-hoc production needs such as experimental runs, engineering trials, or rush orders while following established SOPs.
  • Contribute to material waste tracking and reporting to identify opportunities for reduced scrap and more sustainable operations.
