Products Description
Overview
The Dip Tank Pretreatment System is a critical section in coating production lines, designed to ensure optimal surface preparation before powder coating or painting. By immersing workpieces into a series of chemical tanks, this system effectively removes oil, rust, and contaminants while forming a stable conversion layer to enhance coating adhesion and corrosion resistance.
This solution is widely used for complex-shaped parts, hollow structures, and large workpieces where spray pretreatment may not achieve full coverage.
Working Process
A typical dip tank pretreatment line includes the following steps:
Degreasing
Water Rinsing
Pickling (optional)
Phosphating or Conversion Coating
Final Rinsing
Drying
Workpieces are transported via overhead conveyor or hoist system and immersed sequentially into each tank to ensure uniform treatment.
Key Features
Full Coverage for Complex Workpieces
Immersion processing ensures that internal cavities, edges, and hidden surfaces are fully treated.
Stable and Consistent Quality
Chemical concentration and treatment time can be precisely controlled for consistent results.
Flexible System Design
Tank size, number of stages, and layout can be customized according to product size and production capacity.
Strong Corrosion Resistance Enhancement
Phosphating or other conversion coatings significantly improve coating performance.
