Job Summary
Position Summary
Amcors Injection Molding Division is 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 issues
PLC & 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
