What are the surface treatment methods of Zhuzhou Sheet Metal Processing? Let‘s briefly understand:

Step 1 Drawing

The so-called sheet metal wire drawing is to place the raw material between the upper and lower wheels of the wire drawing machine, and the belt is attached to the wheel. After being started by the motor, the raw material passes through the upper and lower belts, and traces are drawn on the surface of the raw material. According to the difference of the belt, the thickness of the traces is also different, and the key role is to dress up the appearance. In addition, wire drawing is also called rubbing! This surface treatment process is commonly used raw materials: usually aluminum and stainless steel plates are used to study the surface treatment method of wire drawing.

2. Sandblasting

After the wind of the sandblasting machine, the sand grains hit the surface of the workpiece, causing a layer of dense pits on the surface of the workpiece. The key function is to remove dirt and rust on the surface of the workpiece, increase the adhesion of the workpiece surface, and plan for subsequent surface treatment methods. Common raw materials for this surface treatment process: cold-rolled plate, hot-rolled plate, aluminum, etc.

Step 3 Spray paint

Usually refers to liquid spraying, his process has two kinds: liquid baking paint and self-drying spray paint. Self-drying means that after spraying, it can be naturally cured at room temperature, the cost is low, but the effect is not comparable to baking paint. The color effect of spray paint will be better, the thickness of the paint film is relatively thin, suitable for some careful products, and the cost is higher. Zhuzhou sheet metal processing manufacturers commonly use raw materials for this surface treatment process: cold-rolled plate, hot-rolled plate, etc.
