| High Light | Automatic Electrophoresis pretreatment line ，Electrophoretic Coating Spray System ，Pretreatment Line with Electrophoresis | ||
This advanced pretreatment line is engineered to deliver high-quality surface preparation for automotive metal components, providing an essential foundation for electrophoretic (E-coat) finishing. Each stage of the process has been carefully designed to remove contaminants, enhance coating adhesion, and ensure optimal surface condition prior to coating.
A key feature is the acid treatment step, which effectively eliminates oxides and stubborn residues, significantly improving coating performance and durability. The entire line is configured for consistent, efficient operation, utilizing precise process control and intelligent monitoring systems to maintain stability across all parameters—including chemical concentration, temperature, and treatment duration.
The complete pretreatment sequence includes:
Pre-Degreasing
Initial removal of oils and surface contaminants to prepare parts for thorough cleaning.
Degreasing
Deep cleaning phase using chemical degreasers to eliminate residual grease and improve subsequent treatment effectiveness.
Rinse 1
First-stage water rinse to remove any remaining chemical residues.
Rinse 2
Second-stage rinse ensuring cleaner surfaces and reducing cross-contamination.
Acid Treatment
A crucial step that removes oxides, scales, and micro-contaminants while enhancing surface activation for superior coating adhesion.
Rinse 1
Initial rinse to neutralize and wash away acid residues.
Rinse 2
Final rinse to ensure perfectly clean surfaces before entering the electrophoretic coating process.
This pretreatment line is designed for automotive components with maximum dimensions of:
1.1 m × 4 m × 2 m
The system can be customized to accommodate different part sizes, production capacities, chemical systems, and layout requirements depending on your factory space and operational needs.
