Powder Coating Production Line for Die-Forged Conveyor Chains
Powder Coating Production Line for Die-Forged Conveyor Chains
Automated surface pre-treatment and electrostatic powder coating system designed specifically for heavy metal workpieces including castings and forgings. This production line delivers thorough cleaning and high-quality coating preparation through advanced spray technology and automated powder application methods.
Equipment Overview
This fully automated system handles surface pre-treatment processes including degreasing, post-shot-blast cleaning, silane/zirconium treatment, and complete electrostatic powder coating for heavy industrial components.
Working Principle
PLC-controlled operation manages all process parameters including pre-treatment spray pressure, temperature, timing, powder booth negative pressure, electrostatic voltage, and conveyor chain speed. Heavy workpieces progress through multiple automated stages according to programmed specifications.
Core Advantages
  • Full Automation: Continuous operation with minimal manual intervention required
  • High Precision: Programmable parameters ensure consistent treatment of complex geometries
  • Energy Efficient: Circulation filtration and powder recovery systems reduce waste
  • Versatile Applications: Suitable for automotive, construction, agricultural, and heavy equipment components
