Tips: Socket manufacturing process

Blanks (with various specifications) - grinding (removing burrs, etc.) - turning (mainly forming) - grinding the surface - engraving (such as knurling, printing LOGO, etc.) - heat treatment (in order to increase its hardness) - Electroplating (nickel or chromium plating, etc.) - grab black and so on.

The common socket surface treatment are as follows.
1. Bright chrome: like a mirror, very bright.
2. Chromite: dull.
3. Electrophoresis: black with brightness. Under the action of an external DC power supply, the charged particles move towards the cathode or anode in the dispersed medium to promote the separation of substances.
4. Phosphating: black, but dull. The socket is immersed in the phosphating solution, and a layer of water-insoluble crystalline phosphorus is deposited on the surface, which is also the conversion process of phosphate.
