Senior maintenance technicians and mechanical maintenance technicians

Lead the maintenance function for high-speed thermoforming/Form-Fill-Seal water cup production lines. The maintenance supervisor will develop maintenance plans, manage the technical team, respond hands-on to major breakdowns, improve machine reliability, and ensure critical spare parts are available.

Key responsibilities

Prepare daily, weekly, monthly, quarterly, preventive, and shutdown maintenance plans.

Assign maintenance activities and supervise their safe, timely completion.

Lead troubleshooting during major breakdowns and recurring machine failures.

Conduct root-cause analysis and implement permanent corrective actions.

Reduce unplanned downtime and improve equipment reliability and availability.

Coordinate maintenance schedules and machine interventions with production.

Prepare maintenance checklists, SOPs, equipment histories, and technical reports.

Monitor equipment condition and recommend repairs, overhauls, or replacements.

Develop critical spare-parts lists for the complete production line.

Forecast spare-parts requirements and establish minimum and maximum stock levels.

Monitor spare-parts consumption, failure frequency, and component service life.

Prepare accurate technical specifications for purchasing spare parts and services.

Evaluate the technical suitability of proposed replacement components.

Train senior technicians, mechanical technicians, and selected production employees.

Ensure compliance with safety, food-hygiene, and lockout/tagout requirements.

Maintain proper housekeeping and tool control during maintenance activities.

Requirements

Required technical experience

Candidates must have direct, hands-on experience maintaining thermoforming/FFS machines that form, fill, and seal water cups, including:

Plastic-film feeding, tracking, and tension control

Heating and thermoforming stations

Forming molds, vacuum systems, and cooling arrangements

Water-filling mechanisms, nozzles, pumps, and volume adjustment

Lid-film feeding and alignment systems

Heat-sealing temperature, pressure, and timing control

Cutting, punching, and cup-discharge systems

Pneumatic cylinders, valves, regulators, and air preparation

Bearings, chains, sprockets, timing belts, shafts, and gearboxes

Linear guides, conveyors, lubrication systems, and machine alignment

Mechanical synchronization of high-speed production equipment

Experience with Thermonox, Beta-Pak, or technically similar high-speed machines is strongly preferred.

Required qualifications

Diploma or bachelor’s degree in mechanical engineering, mechatronics, industrial maintenance, or a related discipline.

Minimum 7–10 years of relevant maintenance experience.

Demonstrated supervisory experience in a production environment.

Strong mechanical troubleshooting and root-cause-analysis ability.

Ability to prepare preventive maintenance plans, SOPs, checklists, and reports.

Working knowledge of maintenance KPIs, downtime analysis, and spare-parts control.

Ability to read mechanical drawings, manuals, parts diagrams, and specifications.

Willingness to work hands-on and respond to breakdowns outside normal hours when required.

Critical selection requirement

General maintenance experience alone is not sufficient. Candidates whose experience is limited to bottled-water filling lines, RO plants, automotive maintenance, building maintenance, utilities, or unrelated factory equipment will not qualify unless they also have substantial direct experience with thermoform/FFS water cup production machines.
