Seeking a hands‑on EVA Injection Moulding Supervisor / Technician to operate, set up, troubleshoot and maintain EVA shoe‑sole injection moulding machinery while supervising the production team.

This role combines practical machine fault‑finding and repair with production supervision, operator training, quality control, safety and the achievement of daily production targets.

This is not a purely supervisory position. The successful candidate must personally diagnose and repair hydraulic, mechanical, basic electrical, temperature‑control, injection and material‑feeding faults. Candidates unable to troubleshoot and repair injection moulding machinery will not be suitable.

Minimum Requirements:

• Grade 12 / Matric or equivalent; a mechanical, electrical, fitter or millwright qualification will be advantageous.
• Minimum 3 to 5 years' practical experience with injection moulding machinery; EVA footwear or sole production, Chinese EVA machines, mould changes and EVA raw materials will be highly advantageous.
• Demonstrated ability to diagnose machine faults, carry out first‑line repairs and return machinery to production - essential.
• Strong mechanical and hydraulic troubleshooting experience, including pumps, valves, cylinders, hoses, motors, couplings and bearings.
• Basic electrical and PLC fault‑finding ability covering switches, sensors, relays, contactors, wiring, heating elements and temperature controllers.
• Able to set operating parameters, injection pressure, timing, temperatures, hydraulic pressure and moulding cycles.
• Experience supervising production employees, allocating staff, monitoring performance and training machine operators.
• Able to identify production and quality problems caused by the machine, mould, material, operator or process.
• Able to read technical manuals, keep accurate records and follow machine‑safety, isolation, PPE, guarding, emergency‑stop and hydraulic‑pressure‑release procedures.

Duties and Responsibilities:

• Start, operate and shut down EVA injection moulding machines correctly and ensure consistent, safe production output.
• Set and adjust machine parameters, injection pressure, timing, temperatures, hydraulic pressure, moulding cycles, moulds and material feeding.
• Monitor production cycles and identify abnormal noises, leaks, pressure changes, temperature fluctuations and other signs of machine failure.
• Diagnose hydraulic, mechanical, electrical, temperature‑control, injection‑system and material‑feeding faults and carry out repairs or adjustments within the limits of competence.
• Safely isolate machinery, identify the likely cause and provide accurate technical information when specialist assistance is required, then assist with and test completed repairs.
• Complete daily machine inspections and preventative maintenance covering oil levels, lubrication, hoses, fittings, electrical connections, pumps, motors, heating systems, clamping systems, safety switches and emergency stops.
• Identify worn components before failure, maintain the preventative‑maintenance schedule and keep accurate breakdown, repair and maintenance records.
• Allocate operators and production employees to machines and workstations and ensure production schedules and daily targets are followed.
• Monitor attendance, punctuality, machine utilisation, hourly output, downtime, bottlenecks, material wastage, rejection rates and employee productivity.
• Train operators on the correct and safe use of machinery, prevent unauthorised machine adjustments and ensure only competent employees operate equipment.
• Inspect finished EVA products for incomplete injection, deformation, bubbles, overheating, colour, dimensions, surface defects, flash, weight and mould‑definition problems.
• Determine whether quality defects are caused by the machine, material, mould, operator or process and implement corrective action.
• Enforce PPE, guarding, emergency‑stop, housekeeping and machine‑isolation requirements and immediately stop unsafe work practices.
• Report accidents, near misses, dangerous conditions, significant production failures and extended breakdowns to management without delay.
• Maintain daily production, machine‑operation, downtime, wastage, quality, rejection, attendance and inspection records and submit accurate reports to management.
