Job Description:
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. 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. 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. Job Skills & Requirements · Technical Expertise -
In-depth knowledge of HDPE, LDPE, and LLDPE resin properties,
including melt index, density, and thermal behavior; Experience
with multi-layer extrusion. · Process and Quality Control - Skilled
in using SPC tools, data logging systems, and process monitoring
software; Ability to conduct root cause analysis and implement
corrective actions for process deviations. ISO 9001 preferred
experience. · Analytical and Problem-Solving - Strong analytical
skills for interpreting process trends, and material performance;
Ability to optimize blend ratios for cost, performance, and
processability. · Mechanical Aptitude- Knowledge of mold and
machine tooling design and maintenance for polyethylene blends;
Hands-on experience with extruders and gravimetric feeders. ·
Attention to Detail- Ensures product quality and detects equipment
issues early. · Teamwork - Works effectively with technicians,
supervisors, and other team members. Ability and willingness to
train others. · Documentation and Communication - Proficient in
creating and maintaining SOPs, technical reports, and process
documentation; Effective communicator across engineering,
production, quality, and supplier teams; Capable of training
operators and technicians on blend-specific extrusion practices.
Experience managing change orders with strict compliance to
customer-approved specifications. · Basic Troubleshooting Skills -
Identifies and reports machine malfunctions; assists technicians
with repairs. · Time Management - Manages tasks efficiently to meet
production deadlines. · Safety – Observes good safety practices. ·
Willingness to Work Flexible Hours - May include early mornings,
evenings, weekends, or overtime as needed.
