Job Title: Powder Coating Supervisor

Department: Production – Surface Treatment / Finishing

Industry: Switchgear / Electrical Panels / Sheet Metal / Automotive Components

Reporting To: Production Manager / Plant Head

Job Purpose

To supervise and control the complete pre-treatment and powder coating process for sheet metal enclosures and switchgear panels, ensuring high-quality finish, corrosion resistance, productivity, safety, and cost efficiency.

Key Responsibilities

• Process Supervision – Pre treatment Line
  • Supervise complete spray pre‑treatment system; monitor and control chemical concentration (TA/FA ratio), pH levels, temperature, conductivity, sludge removal.
  • Ensure proper phosphating coating weight (g/m²).
  • Troubleshoot issues such as poor adhesion, flash rusting, patchy phosphating, oil contamination.
  • Coordinate with chemical suppliers for corrective actions.
• Powder Coating Line Supervision
  • Supervise electrostatic powder coating booth operations; set and control gun voltage (kV), air pressure, powder flow rate, booth cleanliness.
  • Ensure proper curing parameters: oven temperature, dwell time.
  • Control dry film thickness (DFT) as per specification (80–120 microns typical for switchgear).
  • Monitor first‑pass yield and reduce rejections.
  • Handle shade changes and color changeover effectively.
• Quality Control Testing
  • Perform and monitor cross‑hatch adhesion test, DFT measurement, impact resistance test, gloss measurement, salt spray test (for corrosion resistance).
  • Maintain quality records and inspection reports; ensure compliance with ISO/customer specifications.
• Process Improvement
  • Root cause analysis for peeling, orange peel, pinholes, poor leveling, uneven coating.
  • Implement corrective preventive actions (CAPA).
  • Reduce powder consumption rework rate and improve transfer efficiency.
• Production Management
  • Manpower management: supervise line operators and helpers, plan shift schedules, ensure daily production targets.
  • Maintain 5S and shop‑floor discipline, safety compliance; ensure safe handling of chemicals, maintain MSDS records, proper ventilation and PPE usage, monitor effluent treatment and waste disposal.
