What are the pre-treatment equipment for the painting production line?

       What are the pre-treatment equipment for the painting production line? How to choose? Simply put, the pre-treatment equipment for painting production lines needs to be selected based on factors such as the material, process requirements, surface condition, and cost budget of the workpiece. Generally, there are five common pre-treatment equipment for painting lines, namely anodizing line, spray pre-treatment, immersion pre-treatment, desktop pre-treatment, and gantry pre-treatment. Below, Attractivechina will provide a detailed introduction to each one, Those who don't understand this aspect can follow me to read further.

Anodizing Line

Spray Type Pre-treatment

Immersion Pre-treatment

Desktop Pre-treatment

Gantry Pre-treatment

1. Anodizing line
       Anodized wire is commonly used for surface treatment of aluminum profiles. The principle is to apply direct current to aluminum products under electrolyte and specific process conditions to oxidize the surface of the aluminum product (anode) and form a layer of oxide film. This oxide film has a certain hardness, wear resistance, corrosion resistance, and insulation. It forms a protective layer on the surface of the workpiece and can also be given various colors through dyeing and other methods. The process flow of anodizing line generally includes several steps such as cleaning, acid washing, water spraying, oxidation, and hole sealing, which are suitable for the coating production line of hardware components such as aluminum profiles, aluminum alloys, stainless steel doors and windows, and automotive parts.

        2. Spray type pre-treatment
       Spray pre-treatment is a process in which metal workpieces are placed in a cleaning tank and the cleaning solution in the cleaning pipeline is sprayed onto the surface of the workpiece through high-pressure spraying for cleaning and oil removal. This equipment has a high degree of automation and can achieve automatic control and real-time monitoring, improve cleaning efficiency and quality. It can also achieve cleaning effects on the surface of workpieces of different materials by adjusting parameters such as water temperature, water pressure, and matching ratio of cleaning solution. The cleaning ability and effect ratio are good. This equipment is suitable for pre-treatment work such as oil removal, degreasing, rust removal, and dirt removal before metal surface treatment.

       3. Immersion pre-treatment
       Immersion pre-treatment is the process of placing a workpiece in a material tank and cleaning, phosphating, rust removal, oil removal, and dirt removal on the surface of the workpiece through the liquid in the tank. The specific process generally includes pre cleaning, whitening, phosphating, film formation, rinsing, neutralization, and post cleaning. The entire treatment process is relatively long, but it has a good surface treatment effect on complex workpieces. This processing method is not only beneficial for improving the surface quality of the workpiece, but also enhances the adhesion of the coating and the service life of the product.

       4. Desktop pre-treatment
       Desktop pre-treatment refers to the method of surface treatment of workpieces on a desktop device. This processing method is usually suitable for small and small-scale production of workpieces, including manual spraying, manual cleaning, manual processing, manual abrasive, manual polishing, and other multiple links. The operation is relatively simple and flexible, but it is generally only suitable for small-scale production, with less manpower and time investment, low cost, and can effectively improve the surface adhesion and service life of workpieces. Simply put, purchasers with low budgets or small production scales can choose desktop pre-treatment equipment to complete the pre-treatment work of workpieces, but still need to consider the issue of workpiece size.

       5. Gantry pre-treatment
       Gantry pre-treatment is an upgraded version of traditional immersion pre-treatment equipment. It is a highly automated surface treatment equipment that increases the hanging area of workpieces and improves production efficiency by installing a gantry structure. It is usually used for larger workpieces or products with high surface treatment quality requirements. Therefore, this equipment can be used for pre-treatment in large-scale production painting lines, It can effectively solve the problems of production output and efficiency, and improve the economic benefits of enterprises.

       Speaking of which, I have already introduced the characteristics and advantages of the five pre-treatment equipment for painting lines mentioned above. I hope that after reading this article, everyone can clearly choose the appropriate pre-treatment equipment according to their own products. If you have any questions, please leave us a message.
