Sheet Metal Machining


Sheet metal processing is a hub technology that sheet metal technicians need to grasp, and it is also an important process for sheet metal product forming. Sheet metal processing includes traditional cutting, blanking, bending and forming methods and process parameters, as well as various cold stamping die structures and process parameters, various equipment working principles and operating methods, and new stamping technologies And new technology.

Sheet Metal Machining Material

The materials generally used in sheet metal processing are cold rolled plate (SPCC), hot rolled plate (SHCC), galvanized plate (SECC, SGCC), copper (CU) brass, red copper, beryllium copper, aluminum plate (6061, 5052) 1010, 1060, 6063, duralumin, etc.), stainless steel (mirror, brushed, matte), depending on the role of the product, different materials are used, and generally need to be considered from the product's use and cost.


Cold-rolled sheet SPCC

mainly used for electroplating and baking varnish parts, low cost, easy to shape, material thickness ≤ 3.2mm.

Hot-rolled sheet SHCC

material T≥3.0mm, also uses electroplating, baking varnish parts, low cost, but difficult to form, mainly flat parts.

alvanized sheet SECC, SGCC. SECC

electrolytic board is divided into N material and P material. N material is mainly used for surface treatment and high cost. P material is used for sprayed parts.


mainly uses conductive material, and its surface treatment is nickel plating, chrome plating, or no treatment, which is costly.

Aluminum plate

generally use surface chromate (J11-A), oxidation (conductive oxidation, chemical oxidation), high cost, silver plating, nickel plating, chrome plating, or no treatment, which is costly.

Aluminum profiles

materials with complex cross-section structures are widely used in various sub-boxes. The surface treatment is the same as the aluminum plate.

Stainless steel

mainly used without any surface treatment, high cost.
