Core Responsibilities

Primary Functions

Execute complete and efficient setup, calibration, and changeovers of single and twin-screw extrusion lines, including the installation and alignment of dies, tooling, and downstream equipment.
Operate, monitor, and meticulously adjust process parameters such as screw speed, barrel/die temperatures, line speed, and melt pressure to maintain optimal production efficiency and product quality.
Conduct comprehensive in-process quality control inspections using precision measuring instruments like calipers, micrometers, pin gauges, and optical comparators to ensure products meet all dimensional and cosmetic specifications.
Proactively identify, troubleshoot, and resolve complex process and equipment issues in real-time, addressing common extrusion defects to minimize downtime and reduce scrap rates.
Read and interpret complex technical blueprints, engineering drawings, and production work orders to determine machine setup, material requirements, and final product standards.
Perform first-article inspections at the start of each production run, meticulously documenting results to verify setup accuracy and process capability before commencing full production.
Manage the complete material handling process, including loading hoppers, setting up blenders with correct material/colorant ratios, and ensuring proper drying of hygroscopic materials.
Perform routine operator-level preventative maintenance on extrusion machinery and auxiliary equipment, including thorough cleaning of screws, barrels, dies, and cooling systems.
Operate and synchronize all downstream equipment associated with the extrusion line, such as pullers, cutters, embossers, water baths, winders, and automated packaging systems.
Maintain a highly organized and safe work environment by consistently applying 5S principles and good housekeeping practices within the production cell.
Analyze production data and quality metrics to identify negative trends or opportunities for improvement, collaborating with engineering on process optimization projects.

Secondary Functions

Accurately document all production activities, including process parameter adjustments, quality inspection results, material usage, and machine downtime in the Manufacturing Execution System (MES) or production logbooks.
Adhere strictly to all company safety protocols, including the diligent use of personal protective equipment (PPE) and the proper execution of Lockout/Tagout (LOTO) procedures during maintenance and setup.
Perform detailed die and tooling maintenance, which includes complete disassembly, deep cleaning, visual inspection for wear or damage, and minor repairs to ensure tooling longevity and performance.
Train, mentor, and guide junior operators and new team members on standard operating procedures (SOPs), safety guidelines, and established best practices for extrusion.
Assist the Process Engineering and R&D teams in conducting material trials and process development experiments to qualify new materials, tooling, or process settings.
Participate actively in shift-change meetings, providing clear and concise communication regarding production status, equipment condition, quality concerns, and safety issues to the incoming team.
Monitor and manage the segregation, reprocessing, and recycling of scrap material to minimize waste, control production costs, and support sustainability initiatives.
Maintain an accurate inventory of essential tooling, machine spare parts, and packaging supplies, communicating replenishment needs to the appropriate department.
Contribute to continuous improvement initiatives, such as Kaizen events and Lean Manufacturing projects, by providing expert feedback and suggestions from the production floor.
Ensure all finished products are properly labeled, packaged, and staged for transfer, maintaining lot traceability and preventing damage.
