Maintenance Technician (Electrical/Mechanical)-Injection Molding

Job Description

Job Description

Location:  Thomson, GA

Shift:  Day Shift — with emergency on-call availability as needed

Reports To:  Lead Process Technician / Division Management

Classification:  Hourly, Non-Exempt

Position Summary

Amcor’s 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

•    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

Qualifications

Education

•    High school diploma or GED required

•    Vocational or technical training in electrical, electro-mechanical, or industrial maintenance strongly preferred

•    Formal apprenticeship program, associate degree in a technical field, or equivalent combination of training and experience welcomed

Experience

•    5+ years of hands-on maintenance experience in an injection molding manufacturing environment

•    Must have direct, relevant experience maintaining injection molding presses — this is not a general manufacturing maintenance role

Required Technical Skills

•    Injection molding press maintenance — deep hands-on experience diagnosing and repairing injection molding machines is essential

•    Electrical troubleshooting — ability to trace, diagnose, and repair electrical faults using schematics; confident with control wiring, sensors, drives, and components

•    Hydraulic systems — solid understanding of hydraulic circuits on injection molding machines; ability to diagnose and repair leaks, pressure issues, valve faults, and pump failures

•    Mechanical aptitude — comfortable with general mechanical repair: bearings, belts, couplings, pneumatics, machining basic parts

•    Ability to read electrical schematics, hydraulic diagrams, and mechanical drawings

•    LOTO and electrical safety compliance — must practice and enforce proper lockout/tagout and electrical safety procedures

•    Self-directed — able to diagnose and resolve complex equipment issues independently

Strongly Preferred

•    Direct experience with Milacron injection molding equipment — familiarity with Mosaic or Cemac 486 control systems is a significant advantage

•    PLC troubleshooting experience — ability to navigate PLC diagnostic screens, identify faults, and work through control system errors

•    PLC programming — ability to read, modify, or back up PLC programs (Allen-Bradley, Siemens, or Milacron-specific)

•    Hot runner system maintenance — troubleshooting controllers, tip replacements, wiring repairs

•    Robotics / automation maintenance experience

•    Chiller and cooling system maintenance experience

Personal Characteristics

•    Proactive communicator — surfaces equipment concerns and emerging failures before they impact production

•    Ownership mentality — treats the equipment as their own responsibility and takes pride in uptime and machine condition

•    Problem solver — approaches equipment issues methodically; doesn’t give up until the root cause is identified and resolved

•    Adaptable — comfortable in a growing, fast-paced environment where priorities can shift and initiative is valued

•    Team-oriented — works closely with process technicians, production staff, and division leadership to keep the operation running

Physical Requirements

•    Capable of lifting 50+ lbs unassisted

•    Ability to work in confined spaces, at floor level, and at heights as required

•    Ability to climb stairs, crouch, kneel, and bend

•    Must be able to wear required PPE: steel-toed shoes, safety glasses, gloves, and/or ear protection
