Fabrication of sheet metal processing

SECC hot dip galvanized sheet is divided into N material, P material, N material key without surface treatment, high cost, P material is suitable for spray painting parts.

Copper; key with conductive efficacy materials, equipment sheet metal processing plant surface treatment is electroplated nickel, stainless steel, or no solution, the cost is high.

Aluminum sheet; generally with the surface layer of chromium trioxide (J11-A), oxidation (conductive oxidation, organic chemical oxidation), high cost, with gold plating, electroplated nickel.

Aluminum alloy profile; cross-sectional structure of cumbersome materials, many used in a variety of insert boxes. The surface treatment is the same as aluminum plate.

Stainless steel plate; key with not all surface treatment,,, high cost.

Because of our country's rapid economic splendor and the continuous development of scientific and technological progress, the field of precision parts sheet metal processing has won a rapid development trend and formed a special production process. In general, sheet metal processing mainly consists of four steps: one is to select raw materials for processing, the second is to approve the drawing, the third is to carry out the drawing, and the fourth is to open the material, milling and other processing. In the past sheet metal processing situation, the processing staff occupied an important role.
