What are the surface treatment methods for sheet metal processing

What are the surface treatment methods for sheet metal processing? Let’s briefly understand:

1. Brushed

The so-called sheet metal drawing is to put the raw material between the upper and lower belts of the drawing machine. The belt is attached to the belt, which is activated by the motor to let the raw materials pass through the upper and lower belts, and traces are drawn on the surface of the raw materials. The difference, the thickness of the trace is also different, the key role is to dress up appearance. In addition, wire drawing is also called rubbing! This kind of surface treatment process is commonly used as raw materials: usually aluminum and stainless steel plates are used to study wire drawing surface treatment methods.

2. Sandblasting

The wind force of the sandblasting machine hits the sand particles on the surface of the workpiece, creating a dense layer of pits on the surface of the workpiece. The key function is to remove the dirt and rust on the surface of the workpiece, increase the adhesion of the surface of the workpiece, and do it for the subsequent surface treatment methods. Planning. Common raw materials for this surface treatment process: cold-rolled sheet, hot-rolled sheet, aluminum, etc.

3. Spray paint

It usually refers to liquid spraying. There are two processes: liquid baking paint and self-drying spray paint. Self-drying means that it can be cured naturally at room temperature after spraying. The cost is lower, 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 sophisticated products, and the cost is higher. Commonly used raw materials for this surface treatment process: cold-rolled sheet, hot-rolled sheet, etc.

The above is the surface treatment method of sheet metal processing, I hope it will be helpful to you.
