Job Description Job Description JOB DESCRIPTION
Summary/Objective The Plastics Extrusion Process Engineer is
responsible for optimizing and maintaining extrusion manufacturing
processes to ensure consistent product quality, efficiency, and
safety. This role involves designing, implementing, and improving
extrusion techniques for thermoplastics, troubleshooting equipment
and material issues, and collaborating with cross-functional teams
to support production goals. The engineer will apply technical
expertise in polymer behavior, tooling design, and process control
to drive continuous improvement and innovation in extrusion
operations. Familiarity with 5-layer die and mold systems is
advantageous for maintaining dimensional accuracy and layer
integrity. Essential Functions Extrusion Process Development Design
and optimize extrusion parameters for 5 layer blends of
high-density (HDPE), low-density (LDPE), linear low-density
polyethylene (LLDPE) materials, Admer (adhesive) and EVOH
(barrier). Adjust temperature profiles, screw configurations, and
die designs to accommodate resin-specific flow and cooling
characteristics. Material Handling and Compatibility Evaluate resin
properties such as melt index, density, and additives to ensure
compatibility with extrusion equipment and end-use requirements.
Collaborate with suppliers to qualify new grades of HDPE, LDPE, and
LLDPE for specific applications (e.g., tubing, profiles). Tooling
and Equipment Support Lead tooling trials and implement
modifications to improve dimensional stability and surface finish.
Process Troubleshooting Resolve issues such as melt fracture, die
drool, gel formation, and gauge variation common in polyethylene
extrusion. Use diagnostic tools (e.g., pressure sensors, IR
cameras, rheometers) to identify root causes and implement
corrective actions. Quality Assurance and Compliance Ensure
extruded products meet performance criteria such as tensile
strength, puncture resistance, and elongation, tailored to blend
composition. Support audits and validations for cosmetics grade
polyethylene applications. Confirmation of dimensional accuracy in
wall and layer thickness and ensuring all manufactured parts meet
both internal R4 criteria and externally defined R4 customer
specifications. Documentation and Technical Reporting Maintain
detailed records of blend ratios, process settings, and performance
metrics for traceability and continuous improvement. Generate
technical reports on blend trials, process validations, and
material performance. Continuous Improvement and Innovation Lead
initiatives to optimize blend usage for cost, performance, and
sustainability. Explore advanced blending techniques, co-extrusion
strategies, and recycled content integration. Job Skills &
