The production and processing of metal plates are called sheet metal processing plants. In fact, such as the use of materials to make chimneys, oil drums, oil tanks, air pipes, elbows, Tianyuan, Buchner funnels, etc., the key steps are cutting, sheet metal bending edges, bending forming, welding, riveting, etc., must have a certain degree of Geometric expertise. Sheet metal is sheet metal parts, which can be produced and processed by stamping, bending, stretching and other methods. The consistent understanding is that in the production process, parts with the same thickness should be cast iron, castings, mechanical equipment processing parts, etc.

Material Adoption:

the materials commonly used in sheet metal processing plants are cold rolled steel plate (SPCC), hot rolled steel plate (SHCC), hot galvanized steel plate (SECC.SGCC), copper (CU), red copper, beryllium copper, aluminum plate (6061.6063), aluminum alloy profile, stainless steel plate (mirror glass.

1. cold rolled steel plate SPCC mainly adopts electroplating process and baking varnish process, with low cost, convenient forming and material thickness ≤ 3.2mm.

2. hot rolled steel plate SHCC, material T ≥ 3.0mm, also adopts electroplating process, baking varnish process, low cost, but difficult to shape, with emphasis on tablet computer parts.

3. Hot-dip galvanized SEC.SGCC. SECC electrolytic plate is divided into N material, P material, N material key does not do surface treatment, high cost, P material is used for painting parts.

4. copper: the key is to use conductive materials, and its surface treatment is nickel plating or stainless steel, or it is not solved, resulting in high cost.

5. Aluminum plate: surface chromium trioxide (J11-A), air oxidation (conductive air oxidation, organic chemical air oxidation), high cost, gold plating, nickel plating.

6. aluminum alloy profile: material with complicated cross-sectional structure, many of which are used in various boxes. Surface treatment with aluminum plate.

7. Stainless steel plate: mainly used for all surface treatment stainless steel precision sheet metal, high cost.
