Sheet metal processing is called sheet metal processing. Specific for example, make chimney, iron bucket, oil tank oil pot, ventilation pipe, elbow size head, day garden place, funnel shape, the main working procedure is cutting, bending buckle edge, bending molding, welding, riveting, need certain geometric knowledge. Sheet metal parts are thin plate hardware, which can be processed by stamping, bending, stretching and other means of parts, a general definition is the thickness of the parts in the process of processing. Corresponding to the casting parts, forging parts, machining parts and so on.

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 plate (6061, 6063, hard aluminum, etc.), aluminum profiles, stainless steel (mirror, drawing surface, fog surface), according to the different role of the product, the selection of materials, Generally, the use and cost of the product should be considered.

1, cold rolled 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 use electroplating, paint parts, low cost, but difficult to form, mainly use flat parts.
3, galvanized sheet SECC, SGCC. SECC electrolytic plate N material, P material, N material is not mainly 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, aluminum profile; Materials with complex cross section structure are widely used in various boxes. Surface treatment with aluminum plate.
7, stainless steel; Mainly used without any surface treatment, high cost.
