Sheet metal fabrication process is a comprehensive cold processing process for metal sheets (usually below 6mm), including shearing, punching, bending, welding, riveting, mold forming and surface treatment. The remarkable feature of sheet metal parts is that the thickness of the same part is the same.
Sheet Metal Processing Methods
Through different processing methods, sheet metal processing is usually divided into two categories:
1. Non-mold processing: Process sheet metal through NCT, laser, folding machine, riveting machine and other processing tools. It is generally used for sheet metal prototyping fabrication, the cost is relatively high.
2. Sheet metal mold processing: By making several fixed molds, use the molds to process the sheet metal parts. Generally, there are blanking molds and forming molds, which are mainly used for mass production, and the unit price of the product is low.
1. Require consistency of product quality. The quality of all precision sheet metal stamping parts of the same model is highly consistent, and all products of the same model are completely interchangeable;
2. Assembly suitability. All custom metal stamping parts must achieve perfect cooperation with other various parts in assembly, especially the precision parts of high-precision electromechanical equipment, the required dimensional error is very strict.
3. Production efficiency. That is, compared with other metal forming processes such as casting and forging, the sheet metal stamping process has obvious advantages in terms of production efficiency.
1. Electroplating: In the electroplating solution, charged ions are attached to the surface of the product under the action of an electric field to form a plating layer. Electroplating is a chemical change.
2. Powder painting: The powder is polarized, and under the action of the electric field force, it evenly adheres to the surface of the product with opposite polarity. Powder painting is a physical change.
4. Electrophoresis: Under the action of negative and positive electrodes, the charged paint ions move to the surface of the product and deposit to form a coating. Electrophoresis is a chemical change.
5. Dipping: The product is heated in the molten material, and the heated metal combines with the surrounding molten material to form a certain thickness of the surface material. This surface treatment is a physical change.
There are other surface treatment methods for sheet metal parts such as baking paint, enamel and so on.
