What material should be selected for sheet metal processing?

The materials commonly used in sheet metal processing are hot rolled plate (SHCC), cold rolled plate (SPCC), galvanized plate (SECC,SGCC), copper (CU) brass, beryllium copper, red copper, aluminum plate (6061, 5052, 1010, 1060, 6063, duralumin, etc.), aluminum profile, stainless steel (mirror, brushed, matte), the choice of materials is different, depending on the function of the product, it is often necessary to consider the purpose and cost of the product:

1. Sheet metal processing cold-rolled sheet SPCC, mainly used for electroplating and baking paint parts, easy to form, low cost, material thickness ≤ 3.2mm.

2. Hot-rolled sheet SHCC, material T≥ 3.0mm, also uses electroplated and painted parts, mainly flat parts, low cost but difficult to form.

3. Galvanized sheet SECC,SGCC. SECC electrolytic plates are divided into N material and P material. The N material is mainly used for surface treatment and is costly. P material is used for painting parts.

4. Copper: Mainly made of conductive materials, its surface treatment is nickel plating, chrome plating or no treatment, which is expensive.

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

6. Aluminum profiles; materials with complex cross-sectional structures are widely used in various sub-boxes. The surface treatment is the same as the aluminum plate.

7. Stainless steel: mainly used for metal without any surface treatment, high cost.

Matters needing attention in the development of sheet metal processing industry

In today's economic situation, the development of many industries is difficult. The development of the sheet metal processing industry naturally also has many obstacles. In order to break through the shackles of the existing economic situation, we must grasp every step of our own development. Strive to achieve the sustainable development of the industry, for the sheet metal processing industry, if they want to occupy their own market in the existing market environment, then they must know what they should change and achieve a breakthrough in their own industry.

What are the requirements of precision sheet metal processing for processing materials?

Different precision sheet metal shell need to use different precision sheet metal processing materials to process, is to use stainless steel, or ordinary cold rolled plate, which need to consider the requirements of the precision sheet metal parts to be processed to determine.

What is the process flow of sheet metal processing?

After the drawings are obtained, different blanking methods are selected according to the expansion drawings and batches, including laser, numerical control punching machine, plate shearing, mold and other methods, and then the corresponding expansion is made according to the drawings. CNC punching machine is affected by the cutting tool, for the processing of some special-shaped workpieces and irregular holes, there will be large burrs on the edge, which will have a certain impact on the accuracy of the workpiece. Laser processing has no tool limit and smooth section, which is suitable for the processing of special-shaped workpieces, but it takes a long time to process small workpieces. The workbench is placed next to the numerical control and laser, which is conducive to the processing of the sheet metal on the machine and reduces the workload of lifting the sheet. Some available edge materials are placed in designated places to provide materials for bending test molds.
