Job Purpose

To oversee daily injection moulding production operations, ensuring maximum equipment efficiency, stringent quality control, and optimal resource utilization. This role focuses on driving process optimization, minimizing scrap rates, and leading a high-performing technical team to meet Quality of critical Products.

Key Responsibilities

1. Production & Process Optimization

- Manage daily production schedules to ensure targeted Overall Equipment Effectiveness (OEE) and Output-vs-Plan metrics are achieved.
- Optimize injection moulding process parameters.
- Lead systematic troubleshooting of moulding defects .
- Drive continuous improvement initiatives utilizing Lean Manufacturing, Six Sigma, and 5S methodologies to eliminate waste and rejection.

2. Mold Validation & Technical Trial Management

- Oversee new mold trials and systematic mold validation processes
- Collaborate with the tooling department to ensure preventive mold maintenance is performed and tool life is maximized.
- Execute raw material consumption calculations

3. Maintenance & Asset Management

- Implement and sustain Total Productive Maintenance (TPM) practices, focusing heavily on Autonomous Maintenance (Jishu Hozen) at the shop floor level.
- Coordinate with the maintenance team to schedule planned preventive maintenance (PPM) for injection moulding machines, robots, and auxiliary equipment (chillers, dehumidifiers, and material loaders) to minimize unplanned downtime.

4. Quality Assurance & Compliance

- Ensure absolute compliance with quality management systems (e.g., ISO 13485) by enforcing the use of 7 Quality Control (QC) Tools for root-cause analysis.
- Maintain rigorous process documentation, including parameters sheets, shift logs, production reports, and standard operating procedures (SOPs).
