Precision Industrial Coating Technology
Technology Introduction
Precision industrial coating is a new-generation high-precision spraying technology independently developed by Rocktin, enabling large-area, high-speed and high-precision application. Supported by AI image recognition, it can automatically define and accurately identify non-spraying areas such as electrodes, greatly improving process flexibility. The spraying process is splash-free and eco-friendly. Supporting multi-sided simultaneous spraying and compatible with high-viscosity materials, it offers significant advantages over traditional PET insulation film wrapping.
Core Advantages
Ultra-high precision coating, excellent corner coverage, high productivity, pollution-free
Innovative Side-spray Technology
Supports horizontal and vertical spraying, capable of spraying up to three sides simultaneously
Single coating thickness 50 μm, spraying distance over 5 mm
Only 2-3 passes required to reach target thickness
No Splashing or Residue Throughout the Process
No post-cleaning needed for battery electrodes after spraying
High Spraying & Curing Efficiency
Complete 6-sided spraying and curing of workpieces within seconds
Highly Compatible Nozzles & Special High-viscosity Materials
High-adhesion materials solve traditional PET insulation film peeling and aging issues, greatly extending protective coating life
