INJECTION MOLDING DIE WORKER (MARKET COMPETITIVE)

The Injection Molding Die Worker (BPS-04) serves as a skilled tradesperson within the Industrial Directorate's model workshop or training facility, responsible for the setup, operation, and basic maintenance of injection molding machines and associated dies. The role directly supports plastic component production for government procurement needs and provides hands-on demonstration support for vocational trainees enrolled in mechanical and plastic technology courses.

Daily workflows include reading job cards and mold specifications, mounting and aligning dies on molding machines, setting temperature, pressure, and cycle parameters, and conducting first-article inspections using calipers and gauges. The worker maintains die cleanliness, performs minor repairs such as ejector pin replacement and vent cleaning, logs production output and machine hours in the shop floor register, and ensures strict adherence to safety protocols for hot plastic handling and machine guarding.

Selection for this Category B post is conducted exclusively through a practical trade test and oral viva voce; no written examination is administered. Candidates must demonstrate proficiency in die setting, machine startup, defect identification, and routine maintenance on a live injection molding unit, followed by a technical interview assessing trade knowledge, safety awareness, and workshop discipline.

• ✓Mount and align injection molding dies on machine platens according to setup sheets and engineering drawings
• ✓Configure machine parameters including barrel temperatures, injection pressure, holding time, and cooling cycles
• ✓Inspect molded parts for dimensional accuracy, surface defects, and weight consistency using calibrated measuring instruments
• ✓Perform preventive maintenance on dies including cleaning, lubrication, ejector system checks, and vent clearance
• ✓Record production data, downtime reasons, and material consumption in the daily shop logbook
• ✓Enforce workshop safety standards by verifying guard interlocks, using heat-resistant gloves, and reporting hazards immediately

• 💡Proficiency in reading mechanical drawings and mold assembly blueprints
• 💡Hands-on operation of hydraulic and toggle-type injection molding machines
• 💡Knowledge of thermoplastic material behavior including melt flow, shrinkage, and drying requirements
• 💡Ability to diagnose common molding defects such as short shots, flash, warpage, and sink marks
• 💡Competence in using hand tools, torque wrenches, and precision measuring equipment (vernier, micrometer)
• 💡Understanding of workshop safety regulations, lockout-tagout procedures, and PPE requirements
