product details
type 1: Spray Pretreatment
Powder coating pretreatment refers to the processes used to prepare a surface before applying powder coating, ensuring proper adhesion and a durable finish. Spray pretreatment involves cleaning and treating the surface by spraying cleaning agents and chemicals. This method is efficient and suitable for high-throughput production.
- Uniformity: Spray pre-treatment sprays the cleaning agent and treatment solution uniformly over the entire product surface, ensuring that every area is adequately cleaned and treated.
 - Efficiency: spray pre-treatment enables the cleaning and treatment process to be completed in a short time, making it suitable for high throughput production environments and increasing production efficiency.
 - Flexibility: Spray pre-treatment can be adapted to different product shapes and sizes for a wide range of product types and sizes.
 - Resource-saving: Compared to immersion tank pre-treatment, spray pre-treatment typically requires less cleaning agent and treatment fluid, thus reducing resource consumption.
 
type 2: Dip Tank Pretreatment
Dip tank pretreatment is a process where metal parts are immersed in a chemical solution to prepare the surface for powder coating or other finishes. This method is particularly effective for cleaning, etching, and creating a conversion coating to enhance adhesion and corrosion resistance. It’s commonly used for complex geometries where spray systems might not reach all areas.
- Effective Cleaning:
The immersion process ensures thorough cleaning of the entire surface, even in hard-to-reach areas. - Enhanced Adhesion:
The conversion coating improves the bond between the metal and the final finish. - Improved Corrosion Resistance:
The conversion coating provides a layer of protection against corrosion. - Versatility:
Dip tank pretreatment can be used for various metal types and finishes, including powder coating, paint, and electroplating. 
product Key Stages
- Cleaning: This step removes contaminants like oil, grease, dirt, dust, and rust. Alkaline washes are common for this purpose. 
 - Conditioning: This step prepares the surface for the subsequent conversion coating. 
 - Conversion Coating: This step (such as phosphating or chromating) creates a layer on the metal surface that improves adhesion and corrosion protection. 
 - Rinsing: Rinsing removes any residual chemicals from the surface. 
 - Drying: The final stage involves drying the pretreated metal parts.

Competitive Advantages
- Compact and Space-Efficient Layout: Streamlined spraying mode shortens the system line length, optimizing floor space utilization and reducing facility footprint for cost-effective operations.
 - Advanced Sealing and Ventilation Technology: Water-sealed design isolates steam at the shed body’s top, while integrated wind-through devices prevent acid gas and vapor accumulation, ensuring a safe and stable working environment.
 - Durable Stainless Steel Construction: High-quality stainless steel materials for the shed body, cylinder block, and spray pipes, combined with precision welding techniques, guarantee corrosion resistance and a service life exceeding 15 years.
 - Optimized Flow Control System: Contoured baffles and smooth transitions between sections create a controlled flow field for each process stage, effectively preventing cross-flow and ensuring uniform treatment quality.
