The importance of the pre-treatment system is very important, the pre-treatment process will help make the workpiece surface CLEAN, increase color adhesion, and highly effective product quality.

1. What's a pre-treatment system ? 

To understand more simply and accurately, the pretreatment system is a surface cleaning system with the purpose of making the product surface easier to handle and paint particles more likely to adhere. This is a product cleaning process with a combination of mechanics and chemistry.

- Mechanical cleaning: is a method of cleaning the product surface by scratching or sandblasting. This method of cleaning by mechanical abrasion helps remove dirt, rust, including scratches. scratches on the product surface.

+ Advantages of mechanical cleaning methods: cleans the surface well and saves costs

+ Disadvantage of mechanical cleaning method: painting must be carried out immediately after the surface has been abraded.

- Chemical cleaning: this cleaning method is similar to mechanical in removing dirt, grease, and rust but by dipping, spraying or wiping with chemicals on the product surface.

2. Features of preprocessing system
- Treating the entire product surface

- Clean the product

- Customize treatment chemicals

- High productivity

- Cut costs in the process

3. Classification of pretreatment lines is commonly used today

Pre-treatment lines and product cleaning lines are widely used today, including:
+ Preprocessor pass runs continuously.
+ Embedded preprocessing pass.
+ Pre-treatment transfer to closed chamber.
