Roller Coater for Color Coating Line

As the "cosmetologist" of the color coating Line, this machine integrates sophisticated mechanical structures with advanced electrical automation. Located after the zinc pot, it is responsible for uniformly applying passivation liquid or chrome-free anti-fingerprint solutions onto the strip surface. Through precise gap control, it forms a micron-level dense protective film even at high speeds. This film acts not only as a physical barrier but also as a critical factor in enhancing the adhesion of subsequent painting processes.

Key Features

· Dual-Roller Technology: Separated design of pick-up roll and applicator roll ensures uniform coating thickness without horizontal stripes.

· High-Speed Adaptability: Supports production line speeds up to 280m/min, with coating roller speed reaching 1.5 times the strip speed to prevent zinc powder accumulation.

· Flexible Configuration: Capable of independent top-side, bottom-side, or double-side coating modes.

· Smart Fluid Circulation: Equipped with an independent supply and filtration system to maintain chemical stability.

Customer Value

Significantly improves corrosion resistance (extending salt spray test duration), enhances surface texture, reduces chemical consumption, and lowers production costs.
