Powder Coating Production Line for Branded Frames
Powder Coating Production Line for Branded Frames
Complete automated surface treatment and powder coating system designed for metal frames including bicycle, motorcycle, and automotive subframes.
Equipment Overview
Purpose
Automated surface pre-treatment and electrostatic powder coating for metal frames, delivering efficient cleaning, coating preparation, and superior appearance protection.
Working Principle
PLC-controlled system manages spray pressure, temperature, timing, electrostatic voltage, and conveyor speed through programmed processing stages.
Core Advantages
  • Full Automation: Continuous operation without manual intervention for large-scale production
  • High Precision: Programmable parameters ensure consistent coating on complex tubular sections
  • Energy Efficient: Circulation filtration and heat recovery systems reduce waste and energy consumption
  • Industry Applications: Automotive, motorcycle, e-bike, high-end bicycle, and rehabilitation equipment manufacturing
