Treatment Process Details
Degreasing
  • 6 jigs (racks) per tank × 1 tank = 6 jigs
  • Treatment time: 2-5 minutes
Alkaline Etching
  • 6 jigs (racks) per tank × 2 tanks = 12 jigs
  • Treatment time: 3-15 minutes
Neutralization
  • 6 jigs (racks) per tank × 1 tank = 6 jigs
  • Treatment time: 1-5 minutes
Anodizing
  • 2 jigs (racks) per tank × 3 tanks = 6 jigs
  • Current density: 130A/m²
  • Process time: 30 minutes
  • Unprocess time: 10 minutes
  • Total time: 40 minutes
Average anodizing layer:   10-15µm
Colouring
  • Colour process: Mix Salts
  • 2 jigs (racks) per tank × 1 tank = 2 jigs
  • Current density: 70A
  • Process time: 2-8 minutes
Sealing
  • Sealing method: Sealing at Medium or Normal Temperature
  • 6 jigs (racks) per tank × 1 tank
  • Process time: 10-15 minutes
Design Parameters and Settings
Anodizing Treatment Area
  • Each anodizing process tank requires 40 minutes
  • Total jigs per year: (2 racks × 3 tanks × 60 min/h) ÷ 40 min × 600 hours = 5,400 jigs
  • Design: 57.1m² per jig (each tank: 114.2m²)
  • Area treatment per year: 5,400 jigs × 57.1m²/jig = 308,340m²
Anodizing Treatment Weight
  • Monthly output: 308,340m² ÷ 350m²/T × 0.9 = 792T ≥ 750T
Power Consumption
  • Anodising Tank: 100m²/tank × 130A/m² ÷ 0.9 = 14,444A per tank
  • Power Rectifier: 15,000A = 3 units
  • Colouring Tank: 100m²/tank × 70A/m² ÷ 0.9 = 7,777A per tank
  • Colour Rectifier: 8,000A = 1 unit
