Precision electronics is dongguan relatively large precision stamping processing, main processing mobile phone shell, non-standard precision shrapnel, terminal stamping, precision electronic hardware components manufacturers, the company covers an area of 6000 ㎡, employees 100 people, the technology originated in Taiwan in 1984.
30 years experience in stamping processing, just to be your hardware processing manufacturers more competitive.
Mobile phone shell materials generally for stainless steel, hardness is in commonly 350 hv to 550 hv.
After continuous die stamping.
Stainless steel surface is generally not naked material through special processing.
Lines on the surface of the bare wood is uneven, when the current through the resistance value is not stable, resulting from resistance is relatively large.
If the resistance stability, low resistance, surface should pass the relevant surface treatment, resistance can be controlled within 1 ohm.
According to the mobile phone shell center if there is a belt concave/convex points are divided into points and with no distinction, nickel plated shrapnel in the majority for a bit, for plating silver bullet piece is no point to give priority to.
