What does a senior injection molding process engineer do?

A Senior Injection Molding Process Engineer is responsible for designing, optimizing, and troubleshooting the injection molding process used to manufacture plastic parts. They oversee process improvements, ensure product quality, and collaborate with cross-functional teams to meet production goals. Additionally, they may develop and implement new molding technologies, train staff, and support maintenance of equipment to ensure efficient and reliable operations.

What is the difference between Senior Injection Molding Process Engineer vs Injection Molding Technician?

AspectSenior Injection Molding Process EngineerInjection Molding Technician
CredentialsBachelor's degree in engineering or related field, certifications in process optimizationTechnical diploma or associate degree, on-the-job training
Work EnvironmentDesigning processes, analyzing data, improving production efficiencyOperating machinery, performing setup and maintenance
ResponsibilitiesProcess development, troubleshooting, process validationMachine operation, quality checks, routine maintenance

The Senior Injection Molding Process Engineer focuses on process design, optimization, and troubleshooting, requiring higher-level technical skills and education. In contrast, the Injection Molding Technician handles daily machine operation and maintenance tasks. Both roles are essential in the manufacturing environment but differ in scope and responsibilities.

What are the common challenges faced by senior injection molding process engineers when introducing a new mold into production?

Senior Injection Molding Process Engineers often encounter challenges such as optimizing process parameters for new molds, ensuring part quality meets specifications, and troubleshooting issues like warpage or incomplete filling. Collaboration with design, tooling, and quality teams is essential to address these challenges and implement effective solutions quickly. Additionally, balancing production efficiency with consistent quality requires careful monitoring and adjustment during the initial production runs.

Job description

Senior Process Technician (Injection Molding)Sector: Tier 1 Automotive & High-Precision Electronics

The Role As a Senior Process Technician, you will be the technical backbone of our molding department. You are responsible for the setup, stabilization, and optimization of complex injection molding processes for high-tolerance automotive components and precision electronic housings. We are looking for a "Scientific Molder" who goes beyond "turning knobs" to understand the why behind the polymer 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 IATF 16949 and ISO 9001 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 injection molding environment (Automotive or Electronics experience preferred).

  • Technical Mastery: Strong understanding of RJG, Paulson, or similar Scientific Molding methodologies.

  • Machine Knowledge: Proficiency with major press brands (e.g., Engel, Arburg, Husky, Fanuc, or Milacron) and their respective control systems.

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

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

Preferred Skills & Certifications

  • RJG Master Molder I or II certification is highly desirable.

  • Experience with hot runner systems (Mold-Masters, Yudo, etc.).

  • Familiarity with Lean Manufacturing (5S, Kaizen) and SMED (Single-Minute Exchange of Die) principles to reduce changeover times.

Why Join Us?

  • Cutting-Edge Tech: Work with the latest in all-electric presses and advanced robotic cells.

  • Stability: Long-term career growth within a global Tier 1 supplier.

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