sheet metal bending box

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. SPCC cold-rolled sheet, mainly used in electroplating and paint parts, low cost, easy molding, 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 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 structures are widely used in various boxes. Surface treatment with aluminum plate.

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

The common surface treatment process of the sheet metal:

1. Electroplating: in an electroplating solution, charged ions are attached to the surface of the product under the action of an electric field to form a coating.

2. Powder spraying: the powder is polarized, under the action of electric field force, evenly attached to the product surface of opposite polarity.

3. Electrophoretic coating: Under the action of Yin and Yang poles, charged coating ions move to the surface of the product and deposit to form a coating.

4. Dipping: the product is heated in the molten material, and the heated metal is combined with the surrounding molten material to form a surface material of a certain thickness.
