Injection Moulding Maintenance Engineer

Responsibilities

• Carry out preventive maintenance (PM) tasks on injection moulding machines (Milacron, Haitian, Zhafir, Engel; 80T–1300T) as directed by the Expat Engineer, following prescribed schedules, checklists, and procedures.
• Assist in breakdown diagnosis and execute corrective maintenance actions under instruction from the expat engineer; escalate faults promptly and accurately when beyond scope of assigned tasks.
• Perform routine checks and servicing on hydraulic systems — oil levels, filter changes, seal replacements, valve cleaning, and report abnormalities to the supervising engineer.
• Service and maintain auxiliary equipment, including hopper loaders, dryers, chillers, conveyo systems, and temperature controllers under the direction of the expat engineer.
• Maintain accurate and timely maintenance records for all assigned tasks, including PM completion, parts consumed, breakdown details, and corrective actions taken; submit records within the same shift.
• Monitor assigned machines during production runs, identify early warning signs of mechanical or electrical issues, and report immediately to the expat engineer rather than attempting unsanctioned repairs.
• Ensure all maintenance activities are carried out in compliance with SACVIN safety standards, ISO 45001 requirements, and plant operating procedures; use appropriate PPE at all times.
• Support the expat engineer in spare parts identification, stock verification, and requisition preparation to maintain critical spares availability.

Requirements

• A minimum of an OND in mechanical, electrical, or mechatronics engineering
• Minimum 5 years' hands-on maintenance experience in a plastic injection moulding environment.
• Practical knowledge of hydraulic systems: oil circuits, pumps, valves, seals, and filter maintenance.
• Practical knowledge of electrical systems: heater bands, thermocouples, sensors, solenoid valves, and basic control panel work.
• Ability to follow technical instructions, maintenance checklists, and PM schedules accurately and consistently.
• Familiarity with injection moulding auxiliary equipment: dryers, chillers, hopper loaders, an conveyors
• Ability to read basic hydraulic and electrical diagrams; not required to design or modify circuits.
• Physical fitness for machine maintenance tasks including working at height, lifting tooling, and operating in a production floor environment.
• Good spoken and written English for reporting, maintenance log entries, and communication with the supervising expat engineer.
• Disciplined, safety-conscious, and able to work effectively within a supervised team structure.

Working Relationship

• This role operates under the direct supervision of the injection moulding maintenance engineer (expat).
• The local engineer does not independently own machine availability targets but contributes to plant-wide OEE through disciplined PM execution, accurate fault reporting, and reliable task completion.
