Sheet Metal Machining

Sheet metal production
The main working procedure of sheet metal machining included shearing, bending, bend molding, welding, riveting and so on.Sheet metal parts are thin plate parts, which can be processed by stamping, bending, stretching and other means,that means the thickness keep the same during all the processing in all surface.different from the casting parts, forging parts, machining parts etc.

Selection of materials:

Sheet metal processing materials commonly used are cold rolled sheet (SPCC), hot rolled sheet (SHCC), galvanized sheet (SECC, SGCC), copper (CU) brass, red copper, beryllium copper, aluminum (6061, 5052, 1010, 1060, 6063, hard aluminum, etc.), stainless steel (mirror, drawing surface, fog surface), according to parts application and budget to select related material .

1.Cold rolled sheet SPCC, mainly used in electroplating and paint parts, low cost, easy to form, material thickness ≤3.2mm.

2.Hot rolled plate SHCC, material T≥3.0mm, also used electroplating, paint parts, low cost, but difficult to form, mainly used flat parts.

3.Galvanized sheet SECC, SGCC.SECC electrolytic plate N material, P material, N material no need surface treatment, high cost, P material for spraying parts.

4.Copper;Mainly with conductive materials, its surface treatment is nickel plating, chromium plating, or no treatment, high cost.

5.Aluminum plate;General surface chromate (J11-A), oxidation (conductive oxidation, chemical oxidation), high cost, silver plating, nickel plating.

6.Stainless steel;Mainly used without any surface treatment, high cost.
