Product Specification

Equipment description:

Automobile painting production line equipment description and core structure ‌
‌ The overall overview of the production line ‌
‌ Core goal ‌ : to achieve high-precision and environmentally friendly spraying of auto body and parts, to meet the requirements of weather resistance, corrosion resistance and flawless finish.
‌ Core process ‌ :
Feeding → pre-treatment (degreasing/phosphating) → electrophoresis → primer spraying → leveling → color paint spraying → varnish spraying → curing → cooling inspection → cutting
‌ Technology upgrade point ‌ :
‌ intelligent flexibility ‌ : Support multi-model mixed line production (car /SUV/ new energy models), color change time ≤5 seconds
‌ carbon neutral design ‌ : thermal recovery rate ≥85%, VOC emission ≤15mg/m³ (zeolite wheel +RTO+CO catalytic oxidation)
‌ Digitalization of the whole process ‌ : AI visual quality inspection + digital twin process optimization (product rate increased to 99.5%)
Standard line capacity: 20-30 units/hour (annual output of 500,000 units in double shift system)
Application scenario: OEM complete vehicle spraying, large parts (such as doors/hoods) professional spraying
Certification standards: ISO 50001 (Energy Management), IATF 16949 (Automotive Industry Quality System)
‌ Format description ‌ :
Using modular sections, combined with tables to highlight key parameters, to ensure that technical details at a glance
The timeliness content is clearly marked with the "2025" technical standard to enhance professional credibility
