Maintenance Technician Seeking an experienced Maintenance Technician with deep injection molding and electrical expertise. This is an injection-molding-specific maintenance role focused on keeping our Milacron injection molding presses and all associated auxiliary equipment running at peak performance. The right person has a strong injection molding maintenance background, is genuinely skilled in electrical troubleshooting and repair, understands hydraulic systems on injection presses, and is comfortable working both independently and as part of a small, high-performing team.
Core Responsibilities: Injection Molding Press Maintenance & Repair
- Diagnose, troubleshoot, and repair Milacron injection molding presses, with familiarity with Mosaic and Cemac 486 machine control systems strongly preferred
- Perform emergency and unscheduled press repairs to minimize downtime; respond to production interruptions quickly and effectively
- Develop and maintain a comprehensive Preventative Maintenance (PM) program for all injection molding presses — scheduling, executing, and documenting PMs to prevent failures before they occur
- Maintain a running log of machine health, repair history, & upcoming maintenance needs for each press Electrical Systems
- Diagnose and repair electrical systems on injection molding machines and auxiliary equipment: control panels, wiring harnesses, sensors, proximity switches, solenoid valves, variable frequency drives (VFDs), and other components
- Read, interpret, and work from electrical schematics and wiring diagrams
- Repair or replace electrical components as needed; maintain organized records of replacements & changes
- Ensure compliance with all electrical safety standards including LOTO procedures at all times Hydraulic & Mechanical Systems
- Troubleshoot and repair hydraulic systems on injection molding machines including pumps, valves, manifolds, cylinders, and seals
- Perform mechanical repairs including bearings, belts, couplings, linkages, and general machine components
- Perform machinist tasks as needed for fabricating or modifying parts to support equipment repair & upkeep Auxiliary Equipment
- Maintain, troubleshoot, and repair all auxiliary injection molding equipment including: temperature controllers / thermolators, resin dryers, chillers and mold cooling systems, material loaders and conveying systems, granulators/grinders, conveyors, robots and automation cells, and hot runner controllers
- Ensure all auxiliary equipment is operating correctly and support the process tech team in diagnosing auxiliary equipment issuesPLC & Controls
- Troubleshoot PLC-based machine control faults and work through diagnostic errors on Milacron control systems (Mosaic, Cemac 486)
- PLC programming experience (modifying, updating, or backing up programs) is a significant plus; candidates without prior programming experience who have strong troubleshooting skills will be considered
- Coordinate with corporate electrical maintenance resources on PLC-related projects as needed Support & Coordination
- Interface with Milacron and other equipment vendors for parts sourcing, technical documentation, and specialized repairs — with a goal of progressively reducing external service dependency
- Support mold change process from a mechanical/connectivity standpoint: water connections, hot runner hookups, and press-side mechanical verification
- Manage spare parts inventory for injection molding equipment; identify critical spares and maintain appropriate stock levels
- Communicate machine condition, maintenance status, and upcoming PM needs proactively to the Lead Process Technician and division management
- Maintain complete and organized maintenance records, equipment logs, and service documentation
- Available for emergency on-call response outside normal day shift hours as needed; response expected for critical press downtime situations
- Perform other duties as assigned in support of division uptime and operational goals
