Continuous Color Coating Line — High-Performance Prepainted Steel Coil Production with 3-Coat 3-Bake Technology
Detail Information
Overview
The Continuous Color Coating Line (CCL) is an advanced automated production system engineered for manufacturing high-performance pre-painted steel coils with superior appearance, corrosion resistance, weather durability, and functional surface properties. By integrating precision roll coating technology, multi-stage curing systems, intelligent process control, and online quality inspection, this production line delivers a complete solution for producing premium coated steel products including PVDF fluorocarbon coated steel, HDP high-durability polyester coated steel, and SMP silicone modified polyester coated steel.
Key Features
3-Coat 3-Bake High Film Thickness Technology
Enables premium product positioning with 20–40% higher selling price compared to conventional 2-coat 2-bake products.
Vertical Curing Furnace Design
Reduces floor space by approximately 40% compared to traditional horizontal furnaces, with uniform temperature distribution of ±3℃ for superior coating quality
Fully Automatic Laser Lap Welding
Advanced laser welding technology ensures stable weld quality during high-speed operation, minimizing production interruptions
High Production Efficiency
Coil change time ≤2 minutes, Overall Equipment Effectiveness (OEE) ≥90%, first-pass yield ≥99.3%
Cost-Effective Operation
Production cost reduction of 10–15% compared with traditional coating lines, with high paint utilization efficiency and lower energy consumption
