Quick Detail

Description

The design and processing of the sheet metal chassis are relatively complicated. When it is made, some metal sheets need to be deformed by hand or with tools, and designed into the shape and size required by the customer. In this process , Some parts need to be processed by welding and other methods to meet the design target requirements. The material selection of the sheet metal chassis is very cautious, generally choosing those relatively strong materials.

Note

The main purpose
There are many sheet metal materials suitable for stamping processing. Sheet metal materials widely used in the electronic and electrical industry include:

• Ordinary cold-rolled plate SPCC SPCC refers to the continuous rolling of steel ingots through cold rolling mills into steel coils or sheets of required thickness. There is no protection on the surface of SPCC, and it is easily oxidized when exposed to the air, especially in a humid environment, the oxidation speed is accelerated, and dark red rust appears. The surface should be painted, electroplated or other protection when in use.
• The base material of galvanized steel sheet SECC SECC is general cold-rolled steel coil. After the continuous electro-galvanizing production line goes through degreasing, pickling, electroplating and various post-treatment processes, it becomes an electro-galvanized product. SECC not only has the mechanical properties and similar processability of general cold-rolled steel sheet, but also has superior corrosion resistance and decorative appearance. It is highly competitive and replaceable in the market of electronic products, home appliances and furniture. For example, SECC is commonly used in computer cases.
• Hot-dip galvanized steel sheet SGCC hot-dip galvanized steel coil refers to the semi-finished product after hot-rolled pickling or cold-rolling, washed, annealed, immersed in a molten zinc tank at a temperature of about 460°C, and the steel sheet is plated The zinc layer is then tempered, leveled and chemically treated. SGCC material is harder than SECC material, has poor ductility (avoid deep drawing design), thicker zinc layer, and poor electric weldability.
• The content of stainless steel SUS301 Cr (chromium) is lower than that of SUS304, and the corrosion resistance is poor, but it can get good tensile force and hardness after cold working, and it has good elasticity. It is mostly used for shrapnel springs and anti-EMI.
• Stainless steel SUS304 is one of the most widely used stainless steels. Because it contains Ni (nickel), it has better corrosion resistance and heat resistance than Cr (chromium) steel. It has very good mechanical properties, no heat treatment hardening phenomenon, and no elasticity. .

Precautions for sheet metal painting

• Before the sheet metal spray painting, we must ensure that the sheet metal filter system is clean and check whether the spraying air pressure is normal. If there is no problem, then we should check the paint room water dust separator and For air compressors, this step requires that the painted hose can be kept clean.
• The requirements for sheet metal spray painting are very high. The spray paint hoses, paint mixing tanks and spray guns used in the spray should be placed in a clean place. Of course, in addition to these need to pay attention to cleaning, we must also Before the painting process starts, all other preparation processes are done outside the paint booth to avoid unnecessary pollution of the paint.
