Spray Type Surface Pre-treatment Lines
Uninterrupted Pre-treatment for High-Capacity Facilities
What are Spray-Type Surface Cleaning Lines?
Spray-type surface cleaning lines are automated pre-treatment systems used to remove oil, dirt, oxides, and other surface contaminants from metal parts before the coating process. These systems standardize surface preparation prior to coating, ensuring high-quality and long-lasting paint results.
The system operates on the principle of washing parts—which advance along a conveyor line—at each stage with chemical solutions delivered through pressurized spray nozzles. This ensures homogeneous cleaning across the entire surface while minimizing operator errors.
How Does Spray-Type Surface Cleaning Work?
The system operates on the principle of washing parts—advancing along a conveyor line—at each stage with chemical solutions delivered through pressurized spray nozzles. It typically consists of the following processes:
Degreasing: Removal of oil and industrial residues.
Rinsing: Cleaning off chemical residues.
Phosphating: Creating a conversion coating for adhesion and protection.
Passivation: Increasing corrosion resistance.
Final Rinsing: Clearing the surface for the drying stage.
Advantages of Spray-Type Surface Cleaning Lines
High cleaning efficiency
Homogeneous surface preparation
Increased coating adhesion
Improved corrosion resistance
Low error and scrap rates
Continuous and stable production
Spray-Type Surface Cleaning Line Prices
Prices for spray-type surface cleaning lines vary depending on the technical specifications of the system and the process structure.
The main factors determining the price are:
Number of baths (stages): The more stages in the process, the higher the cost.
Line length and capacity: Larger systems designed for higher volume require more investment.
Chemical processes used: The type of treatment (e.g., Nano, Zinc Phosphate) affects equipment choice.
Material construction: Systems can be built from DKP (mild steel) or stainless steel.
Automation level: Smart control systems and equipment details influence the final cost.
Since the system length and equipment requirements increase directly with the number of baths, costs are significantly affected by the complexity of the process. It is recommended to have a custom system designed for your specific needs to get the most accurate project pricing.
