At first, the metal hot rolling (metal hot coil) by roll compacting stainless steel or phosphor bronze forms super thin metal plate as the basic material of shift knob element to predetermined thickness.
The sheet metal (metal sheet) that forms by roll compacting metal hot rolling is because of its internal pressure is in hardened condition, so the internal pressure of sheet metal must be eliminated so that high resiliency to be provided, so that this super thin metal plate can be used as the shift knob element.
For this reason, in usual method, come the heat-treated metal thin slice with the elimination internal pressure, and high resiliency is provided at 450-520 ℃.
If at 450-520 ℃ of heat-treated metal thin slice, then can obtain the high resiliency of sheet metal, still on the surface of sheet metal, will form the dirt (scale) of non-expectation according to usual method.If form dirt on the surface of resilient blade, because the interference of dirt, plating uniformly just becomes very difficult on resilient blade, and causes being used for the quality of super thin metal plate of shift knob element and the deterioration of durability.
In order to address the above problem, use acid to clean resilient blade, like this can form the oxide-film that promotes electroplating effect, and eliminate the lip-deep dirt of resilient blade simultaneously.
If use acid to clean resilient blade, can eliminate the dirt that influences electroplating effect on the resilient blade, and on the surface of resilient blade, form the oxide-film that promotes electroplating effect.
After forming oxide-film, come resilient blade is electroplated and generate the cover layer of nickel or silver on the surface of resilient blade by using nickel or silver.
