Do you know what materials are needed for precision sheet metal processing?

What materials are generally used for precision stainless steel sheet metal processing? The materials generally used in sheet metal processing are cold-rolled sheet, galvanized sheet, copper sheet, aluminum sheet, stainless steel sheet, aluminum, etc.; their roles are different, as to how to choose, generally need to consider from the use and cost

1, cold-rolled sheet: used for surface treatment is electroplated five-color zinc or baking paint parts use.

2, galvanized sheet: used for surface treatment is baked paint parts use.

3, copper plate: generally used for nickel-plated or chrome-plated parts, sometimes without treatment. Depending on customer requirements.

4, aluminum plate: generally used for surface treatment is chromate or oxidation parts use.

5, stainless steel plate: divided into mirror stainless steel and matte stainless steel, it does not need to do any treatment.

6、Aluminium profile: generally used for surface treatment of chromate or oxidized parts by the enclosure sheet metal processing factory. Mainly play a supporting or connecting role, a large number of plug boxes used in a variety of;.

7、Stainless steel: The main role is not to make any surface treatment, but the cost is high.

Sheet metal unfolding notes unfolding diagram is based on the parts diagram (3D) unfolding plan (2D): 1.

1、The unfolding method should be reasonable, to facilitate material saving and processability

2、Reasonable choice of gap and edge wrapping method: T=2.0 or less gap 0.2, T=2-3 gap 0.5, and long edge wrapping method for short edge (door panel)

3, reasonable consideration of tolerance shape size: negative difference go to the end, positive difference go half; hole shape size: positive difference go to the end, negative difference go half.

4、Burr direction

5, draw teeth, riveting, tearing, punching bump (package), such as the location of the direction, draw the section view

6, check the material, plate thickness, to plate thickness tolerance

7, special angle, bending angle inside the radius (generally R = 0.5) to try to fold depending on the unfolding

8、Make sure to highlight any error-prone areas (similar asymmetry).

9、The places with more customized dimensions for precision sheet metal processing should be added with enlarged drawings.

10、The places that need to be protected by spraying should be indicated;
