Discussion on Common Materials for Sheet Metal Processing

Sheet metal processing is mainly based on metal materials, sheet metal processing commonly used materials are:

1. Sheet metal processing-galvanized steel sheet SECC

The base material of SECC is ordinary cold-rolled steel coil, which becomes electro-galvanized product after degreasing, pickling, electroplating and various post-processing processes of continuous electro-galvanized production line. SECC not only has the same mechanical properties and workability as general cold-rolled steel sheets, but also has excellent corrosion resistance and decorative appearance.

2. Sheet metal processing-ordinary cold rolled sheet SPCC

SPCC refers to the continuous rolling of steel ingots through a cold rolling mill into steel coils or sheets of the required thickness. The surface of SPCC has no protective layer and is easily oxidized when exposed to air, especially in a humid environment, the oxidation rate is accelerated and dark red rust appears. Paint, electroplating or other protective measures should be applied to the surface during use.

3. Sheet metal processing-hot-dip galvanized steel SGCC

Hot-dip galvanized steel coil refers to a semi-finished product after hot-rolled, pickled or cold-rolled, cleaned and annealed, and then immersed in a molten zinc bath at about 460°C, so that the surface of the steel sheet is plated with a layer of zinc, followed by quenching and tempering and chemical treatment.

4. Sheet metal processing-stainless steel SUS304

One of the most widely used stainless steel. Because it contains nickel (nickel), it has better corrosion resistance and heat resistance than chromium (chromium) steel. It has very good mechanical properties, no heat treatment hardening phenomenon, and no elasticity.

5. Sheet metal processing-stainless steel SUS301

The content of Cr (chromium) is lower than that of SUS304, and the corrosion resistance is poor. However, good tensile force and hardness can be obtained in the stamping after cold working, and good elasticity. It is mainly used for shrapnel spring and anti-electromagnetic interference.

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.
