In the next few years, Changchun will become a car city with an annual output of 2 million cars. At present, what new issues and opportunities are faced by Changchun's spare parts industry, how to solve these new problems and seize these new opportunities? In the afternoon of July 27th At the Changchun Automobile Parts Industry Development Seminar held, the experts Jia Xinguang and Cao Jiansheng, general manager of Frankfurt (Shanghai) Exhibition Co., Ltd. respectively gave a keynote speech on the topic of the development of the auto parts industry. The reporter learned that the future 3— In the past five years, Changchun will focus on the implementation of the "Five Firsts" project to vigorously upgrade and expand the auto industry.

The reporter learned that Changchun is the cradle of the Chinese auto industry and is currently the largest and most powerful automobile R&D and manufacturing base in China. Up to now, the total vehicle production capacity of the city has exceeded 1 million, and the number of related enterprises in the city surrounding the automobile industry has exceeded 400. Relying on the employment capacity provided by these enterprises, it accounts for more than half of the city’s industrial enterprises providing jobs. At present, the automobile industry has accounted for more than 65% of the city's industrial output value above designated scale, and it is well-deserved to become the absolute dominant force supporting Changchun’s reform, construction, revitalization and development.

Zinc or Nickel Plating Production Line

Metal electroplating line is widely used in aircraft and auto parts, machinery parts, metal, hardware processing industries, including cooper plating, silver plating, zinc plating, nickel plating, gold plating, chrom plating, anodizing, electrophoresis production line,etc.

Zinc-nickel alloy is an anti-corrosion coating with excellent corrosion resistance. At the same time, it has good mechanical properties and does not change the mechanical properties of the steel after plating. It has excellent brazing properties and is easy to weld under various conditions. The internal stress of the coating is small, which is comparable to that of the cadmium coating in the torsion-tension test. The plating solution has good dispersing ability and covering ability, high current efficiency, bright and smooth coating.
The zinc-nickel alloy plating bath has weak acid chloride type, sulfate type and alkaline zinc acid type.

The surface condition and processing requirements during electroplating, select the appropriate steps, and perform the necessary finishing processing on the surface of the part, so that the part has a smooth and clean surface, which is an important link in obtaining a high-quality coating.
