Product Description

The workpieces coated by this automatic powder coating line are shelves, and the length of the hangers is 13.5 meters. The material of the spray booth is PP, and the spraying method combines automatic gun spraying and additional manual coating, and the production line adopts the power & free overhead system, and the parts are loaded and unloaded manually.


All of our powder coating production lines are designed according to client's products and demands. A more accurate quotation needs to be calculated according to the parameters of the coating production lines you need.


Please contact us and a detailed specification for the discussion will be very much appreciated. Feel free to contact us to get your exclusive design proposal. We can also customize other types of coating production line based on product characteristics.


The Process of Powder Coating Line:


1. Surface Preparation:
  • Initial cleaning process removes:
    • Surface contaminants
    • Oils and greases
    • Oxidation layers

  • Ensures optimal coating adhesion

2. Pre-Treatment:
  • Chemical conversion coatings:
    • Phosphating (zinc or iron phosphate)
    • Chromate conversion
    • Specialty chemical treatments

  • Provides:
    • Enhanced corrosion resistance
    • Improved powder adhesion

3. Drying Process:
  • Controlled thermal drying removes:
    • Residual moisture
    • Chemical traces

  • Achieves water-free surface for coating

4. Powder Application:
  • Electrostatic spray deposition:
    • 50-100kV charging voltage
    • Grounded workpiece attraction

  • Ensures:
    • Uniform coating thickness (±5μm)
    • Complete surface coverage

5. Powder Curing:
  • Oven parameters:
    • 180-200°C curing temperature
    • 10-15 minute dwell time

  • Creates:
    • Continuous polymer film
    • Cross-linked molecular structure

6. Cooling:
  • Stabilization phase:
    • Ambient or forced air cooling
    • Prevents thermal stress

7. Quality Assurance:  
  • Inspection criteria:
    • Coating thickness (micrometer check)
    • Adhesion (ASTM D3359 cross-hatch test)
    • Visual appearance (gloss, color consistency)
    • Hardness (pencil or Buchholz test)
