Electro‑Mechanical Service Technician, Blow Molding Systems

Job Description

Job Description

Your mission: keep production flowing

Every part we ship depends on reliable blow molding and injection systems. As our Electro‑Mechanical Service Technician, you’ll blend mechanical savvy, electrical skill, and a reliability mindset to maximize uptime and quality—safely.

• Restore performance on blow molding and injection machines by diagnosing hydraulic and pneumatic faults quickly and accurately.
• Maintain precision components—extruders, screws, barrels, die heads—as well as clamp systems, molds, and tooling.
• Ensure auxiliary equipment is dependable: conveyors, loaders, dryers, chillers, cooling towers, air compressors, and vacuum pumps.
• Support downstream operations, including trimmers, leak testers, and automation cells.
• Execute efficient mold changeovers, product startups, and full line changeovers.
• Drive process optimization to cut scrap and shorten downtime.

• Carry out PMs on schedule; use findings to prevent future failures.
• Document all work, parts, and asset conditions in the CMMS to build equipment history.
• Recommend reliability enhancements and standard fixes for recurring issues.
• Help create and refine PM procedures specific to blow molding assets.

• Troubleshoot PLC-controlled machinery, HMIs, VFDs, and basic robotics.
• Resolve issues with 480V systems, motors, sensors, relays, and control panels.
• Complete safe, code-aligned wiring, control panel, and instrumentation repairs.

• Model OSHA compliance and strict Lockout/Tagout (LOTO) discipline.
• Keep your workspace orderly and contribute to 5S, Kaizen, and TPM efforts.
• Engage in audits and inspections and follow through on action items.

• High school diploma or GED; technical schooling or certification preferred.
• 3+ years maintaining equipment in plastic blow molding or similar manufacturing.
• Expert mechanical troubleshooting across hydraulics, pneumatics, and complex mechanisms.
• Solid understanding of 480V power, motors, and industrial controls.
• PLC exposure (Allen‑Bradley, Siemens, or comparable), with HMI and VFD familiarity.
• Ability to interpret blueprints, electrical schematics, and P&IDs.
• Comfort with hand and power tools.
• Availability for overtime, weekends, and on-call rotations as needed.

A downstream leak tester trips and upstream scrap rises. You pull the fault history from the HMI, verify sensor inputs at the PLC, check relay operation, and confirm VFD settings. After a quick pneumatic inspection, you identify a cracked line causing inconsistent clamping. You lock out, replace the line, validate operation, and document the repair and parts used in the CMMS—then adjust PMs to include an added inspection step.
