Blow Molding Equipment Reliability Technician

A day in this role

You roll in, review the CMMS for overnight work orders, and head straight to the floor. A blow molding line is warming up—you verify hydraulics and pneumatics, check extruder barrel temperatures, and listen for the telltale rhythm of a healthy clamp system. Minutes later, you’re diagnosing a sensor fault on a PLC-controlled trimmer, then pivoting to support a mold changeover that keeps scrap to a minimum and throughput on target.

Core responsibilities

Mechanical and process stewardship

• Service, troubleshoot, and restore blow molding and injection equipment to optimal operation, including hydraulic and pneumatic subsystems.
• Work hands-on with extruders, screws, barrels, and die heads; maintain clamp systems, molds, and tooling for consistent quality.
• Keep auxiliary systems running: material handling (conveyors, loaders, dryers), chillers, cooling towers, air compressors, and vacuum pumps.
• Support downstream assets such as trimmers, leak testers, and automation cells.
• Lead and assist with mold changeovers, startups, and line changeovers; help fine-tune processes to cut downtime and scrap.

Electrical and controls expertise

• Diagnose and repair PLC-driven equipment, HMIs, VFDs, and basic robotics.
• Resolve electrical issues involving 480V power, motors, sensors, relays, and control panels.
• Perform safe, standards-compliant wiring, panel work, and instrumentation repairs.

Preventive and predictive maintenance

• Execute scheduled PM tasks and inspections with discipline.
• Document work performed, spare parts used, and equipment condition in the CMMS.
• Spot patterns, recommend reliability upgrades, and implement fixes for recurring issues.
• Contribute to the development and revision of PM procedures specific to blow molding assets.

Safety, quality, and compliance

• Adhere to OSHA, Lockout/Tagout (LOTO), and all site safety procedures; leave every area safer than you found it.
• Maintain an orderly work environment and support 5S, Kaizen, and TPM initiatives.
• Participate in facility and equipment audits/inspections and close out findings.

What you bring

• High school diploma or GED; technical degree/certification preferred.
• 3 years of industrial maintenance experience within plastic blow molding or closely related manufacturing.
• Proven mechanical troubleshooting ability across hydraulics, pneumatics, and complex mechanical systems.
• Working knowledge of 480V electrical, motors, and industrial controls.
• PLC familiarity (Allen-Bradley, Siemens, or equivalent preferred) and comfort with HMIs and VFDs.
• Ability to interpret blueprints, electrical schematics, and P&IDs.
• Proficiency with common hand and power tools.
• Flexibility to support overtime, weekends, and on-call needs.
