Blow Moulding Maintenance Engineer

Responsibilities:

• Carry out preventive maintenance (PM) tasks on blow moulding machines (CMP 0.5L to Jagmohan 100L) as directed by the Expat Engineer, following prescribed schedules, checklists, and plant procedures.
• Assist in breakdown diagnosis and execute corrective maintenance actions under instruction from the Expat Engineer; escalate faults promptly and accurately when beyond the scope of assigned tasks.
• Perform routine servicing on hydraulic and pneumatic systems oil level checks, filter changes, seal replacements, solenoid valve cleaning, air line maintenance, and report abnormalities to the supervising engineer.
• Maintain and service automated deflashing systems checking mechanical alignment, pneumatic actuators, and trimming blades — under the direction of the Expat Engineer; report deflash quality issues immediately.
• Carry out electrical maintenance tasks, including sensor replacements, heater band changes, thermocouple replacements, proximity switch adjustments, and control panel cleaning as directed; avoid unauthorised access to PLC or drive configurations.
• Service and maintain auxiliary equipment, including air compressors, chiller systems, convey or belts, cooling water circuits, and material handling systems under the direction of the Expat Engineer.
• Support size/mould change-over activities carrying out physical mould handling, blow pin changes, water line connections, and die gap pre-setting — working as part of the change-over team under expat supervision.
• Monitor assigned machines during production for early signs of parison variation, flash abnormalities, or mechanical faults; report immediately to the Expat Engineer rather than attempting unsanctioned adjustments.
• Maintain accurate and timely maintenance records for all assigned tasks, including PM completion, parts consumed, breakdown details, and corrective actions; submit records within the same shift.\
• Ensure all maintenance activities comply with SACVIN safety standards, ISO 45001 requirements, and plant operating procedures; use appropriate PPE at all times on the production floor.

Requirements:

• OND in Mechanical, Electrical, or Mechatronics Engineering.
• Minimum 5 years of hands-on maintenance experience in a plastic blow moulding environment.
• Practical knowledge of blow moulding hydraulic and pneumatic systems: cylinders, valves, seals, accumulators, and air circuits.
• Practical experience with automated deflashing systems mechanical, pneumatic, or servo-driven, and the ability to carry out alignment and blade/tooling changes.
• Familiarity with electrical maintenance tasks: heater bands, thermocouples, proximity sensors, solenoid valves, and basic panel work.
• Understanding of PP and HDPE material behaviour in blow moulding flash formation, cooling, and shrinkage — sufficient to identify product quality issues and report accurately
• Ability to follow technical instructions, maintenance checklists, and PM schedules accurately and consistently.
• Familiarity with auxiliary equipment: air compressors, chillers, conveyors, and cooling water circuits.
• Physical fitness for machine maintenance tasks, including mould handling, working at height, 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 and 4- person shift structure.
