Case Study | Geetech: Automatic Spray Painting Line for Automotive Parts in Zhejiang

An automotive parts manufacturer in Zhejiang was facing inconsistent manual coating quality, fluctuating film thickness, and growing VOC compliance pressure on automotive exterior parts (bumper trims, grilles, mirror housings, etc.). As a professional automatic spray painting line manufacturer, Geetech delivered a complete automatic spray painting line for automotive parts covering the entire process from pre-treatment to curing:

• Automatic spraying section: 5-axis reciprocating spray machine (optional robotic spraying line) with constant-pressure paint supply system and temperature/humidity control, delivering uniform film thickness with no runs or sagging on complex curved surfaces and edges — ideal for bumpers, grilles, trim strips and other automotive exterior parts painting;
• Curing section: Multi-zone tunnel curing oven with independent temperature control across pre-heat/leveling, constant-temperature curing and slow-cooling zones, meeting both fast-curing and high-hardness requirements of solvent-based paint;
• Environmental & safety section: Integrated zeolite rotor + RTO exhaust gas treatment system with VOC removal efficiency ≥95% and emission concentrations consistently below national limits; full-area explosion-proof spray booths, explosion-proof electrical systems and combustible gas monitoring for compliant and safe operation;
• Intelligent management: Centralized PLC + HMI control with full process parameter traceability, meeting OEM audit requirements.
