Process Technician (Blow Molding)

The Role
As a
Process Technician
, you will be the technical backbone of our molding department. You are responsible for the setup, stabilization, and optimization of complex molding processes for consumer products and beverage bottles. We are looking for a "Scientific Molder" who goes beyond "turning knobs" to understand the why behind the material and process behavior.

Core Responsibilities
  • Scientific Process Development:Establish and maintain robust "decoupled" molding processes (Scientific Molding) to ensure consistent part quality and cycle time optimization.

  • Technical Troubleshooting:Diagnose and resolve complex molding issues (e.g., flash, splay, short shots, dimensional instability) using root-cause analysis rather than "trial and error."

  • New Product Launch (NPI):Work closely with Engineering during mold trials (sampling) to define the process window and provide feedback on mold design and functionality.

  • Automation Integration:Coordinate with the automation team to ensure 3-axis or 6-axis robots (end-of-arm tooling) are synchronized with the press for seamless part extraction.

  • Quality & Compliance:Ensure all processes adhere to
    quality
    standards. Perform first-piece inspections and monitor SPC (Statistical Process Control) data to prevent defects.

  • Mentorship:Act as a technical lead for junior technicians and operators, fostering a culture of technical excellence and safety.

Key Qualifications
  • Experience:5+ years of hands‑on processing experience in a high-volume blow molding environment

  • Technical Mastery:Strong understanding of Molding methodologies.

  • Machine Knowledge:Proficiency with major press brands (e.g., Sipa, Sidel, Uniloy, Jomar) and their respective control systems.

  • Material Expertise:Deep knowledge of resins (e.g., PET, Nylon/GF, PC/ABS) and their specific processing requirements.

  • Tooling Logic:Ability to identify mold issues (venting, cooling, gate wear) versus processing issues.

Why Join Us?
  • Cutting-Edge Tech:Work with the latest in blow molding presses and advanced robotic cells.

  • Stability:Long-term career growth within a global supplier.

  • Comprehensive Benefits:Competitive hourly rate/salary, overtime opportunities, 401k/RRSP matching, and premium health coverage.
