High End Technology Sheet Metal Fabrication Service

High End Technology Sheet Metal Fabrication Service

Sheet metal is a comprehensive cold working process of sheet metal (generally less than 6 mm), which specifically includes cutting, punching/cutting/composite, folding, welding, riveting, splicing, forming (such as automobile body), etc., and its prominent feature is that the thickness of the same part is the same. Sheet metal usually refers to products made from steel plates and steel plates by stamping or forging, and the surface usually has stamping or forging marks, so it is also called stamping or forging parts.
What is said in different industries is usually different, mainly used for assembly. However, in the sheet metal industry, sheet metal is also commonly referred to as sheet, because it needs to be punched/cut/combined, folded, welded, riveted, spliced and other steps during manufacturing. Among them, punching/cutting/compound refers to the first hole on the steel plate for punching or stamping, and then cutting; Folding refers to the two holes on the steel plate into a hole; Welding refers to the connection of two holes in the steel plate together; Riveting refers to the two holes in the steel plate fixed together; Splicing refers to the assembly of multiple steel plates into a whole by welding or riveting.

sheet material

There are many kinds of sheet material suitable for stamping processing. Board materials used in the electronic and electrical industries are:
1, ordinary cold rolled sheet SPCC
Ultrathin sheet is a roll or sheet of iron ingot rolled continuously by a cold mill to a certain thickness. As SPCCS are unprotected, they are easily oxidized in the atmosphere, especially in the case of high humidity, which will accelerate oxidation and produce dark red rust.
2. Galvanized steel SECC
SECC is made of common cold rolled strip steel after degreasing, pickling, electroplating and other post-processing. Its mechanical properties are equivalent to those of ordinary cold rolled steel, but its technological properties are equivalent to those of ordinary cold rolled steel, and it has better performance in rust prevention, decoration and other aspects.
3. SGCC of hot-dip galvanized steel plate
Hot-dip galvanized coil is a semi-finished product obtained by hot rolling, pickling and cold rolling, after cleaning, annealing, it is immersed in a zinc solution at a temperature of about 460 degrees Celsius, in this solution to form a layer of galvanized layer, and then conditioning treatment. Flattening and chemical processing.
4. Stainless Steel SUS301
Cr content is lower than SUS304, poor corrosion resistance, after cold processing has good tensile strength, hardness and elasticity. Shrapnel springs used mainly to protect against electromagnetic interference.
5. Stainless Steel SUS304
As a commonly used stainless steel, its main component is Ni, compared with Cr, Ni content is higher, its mechanical properties are better, and will not occur any heat treatment hardening, there is no elasticity.
