Detail

Applicable Products and Common Manufacturing Applications

The HD-380-7S-B coating spray machine is mainly used for bicycle frame surface coating and various housing surface finishing applications. It is especially suitable for multi-tube structures and complex geometric designs. This type of system is often integrated into automatic powder coating equipment production lines to improve efficiency and consistency.

Common Application Products

  • Road bike frames and mountain bike frame coating
  • Aluminum alloy frame surface treatment
  • Steel frame exterior coating
After introducing an automatic powder coating equipment system, frame surface coating becomes more consistent in appearance, making it suitable for mass production and high-quality surface requirements.

Common Problems and Improvement Methods in Frame Coating

Typical Production Line Issues

  • Tube intersections causing incomplete coating coverage
  • Uneven coating thickness at welding areas
  • Color change affecting production cycle timing
  • Inconsistent manual operation stability

Improvements After Automation Implementation

By using fixed spraying paths and stable material supply control, each bicycle frame follows a consistent coating process, reducing human variation and improving overall production stability of automatic powder coating equipment systems.

Advantages of HD-380-7S-B Coating Spray Machine

  • Full digital computer control system (Windows-based interface)
  • Five-axis synchronous operation design with five independent drive motors
  • Supports five-axis motion and four-axis auxiliary spraying for complex angles
  • Continuous and stable spraying performance, suitable for curved and 3D structures
  • Multiple coating parameter storage (depending on hard disk capacity)
  • Product coating database creation and classification management
  • Adjustable spray width, spray volume, and paint flow control
  • Graphical programming and manual teaching mode for easy operation setup
