Plastics Engineer

Key Responsibilities:

Process Development & Optimization

Manage new EBM facility project

Set up and fine-tune EBM machines for HDPE bottle production (e.g., Bekum, Kautex, Jomar, Uniloy, or equivalent).

Optimize parameters for parison programming, cooling cycles, trimming, and deflashing.

Implement process improvements to enhance bottle consistency, reduce cycle time, and increase throughput.

Mold & Tooling Management

Provide technical input on blow mold design and venting, especially for complex bottle geometries.

Lead mold changeovers and assist with first article inspections and mold trials.

Collaborate with tooling suppliers to resolve mold wear, hot spots, and parting line flash issues.

Troubleshooting & Maintenance Support

Diagnose and resolve production issues such as uneven wall thickness, short shots, flash, leaks, or poor dimensional control.

Partner with maintenance to ensure uptime of extrusion heads, die lips, and clamping systems.

Quality & Compliance

Monitor wall thickness profiles, bottle weights, and dimensional tolerances.

Support quality assurance by ensuring compliance with GMP, ISO 9001, and customer specifications.

Develop and maintain standard operating procedures (SOPs) and process control documentation.

Sustainability & Cost Efficiency

Drive material efficiency through light weighting, resin optimization, and cycle time reduction.

Support integration of post-consumer recycled (PCR) HDPE without compromising bottle integrity.

Qualifications:

Bachelor’s degree in Mechanical Engineering, Plastics Engineering, or related field preferred.

10+ years experience specifically with extrusion blow molding of HDPE bottles.

Strong hands-on experience with parison control, trimming systems, and deflash.

Familiarity with machine platforms such as Bekum, Kautex, or Uniloy.

Proficiency in troubleshooting molding defects and process deviations.

Solid understanding of polymer behavior, especially HDPE and blends.

Knowledge of statistical process control (SPC), lean manufacturing, and root cause analysis.
