Electroplating is a widely used basic process in industry, which exists in many industries such as electromechanical, instrumentation, electronic communication, light industry, automobile, shipbuilding, aerospace, etc.
Electroplating is a widely used basic process in industry, which exists in many industries such as electromechanical, instrumentation, electronic communication, light industry, automobile, shipbuilding, aerospace, etc. It plays a role in the decoration, protection, and other surface functions and performance generation, modification, and optimization of products, improving product quality, obtaining or improving functions, optimizing performance, beautifying appearance, extending service life, and increasing added value of goods. It has unique application value, It is an indispensable craft industry in the national economy.
Shanghai is the birthplace of China's electroplating industry, with a history of 100 years. The electroplating industry in Shanghai started from the jewelry and printing industries, and later expanded to the machinery and daily hardware industries. The earlier plating methods were gold, silver, and copper plating, followed by nickel plating and then chromium plating. At the beginning of the 20th century, Shanghai's first batch of professional electroplating factories emerged, and the independent electroplating industry began to take shape. By the 1940s, specialized factories had formed a relatively detailed division of labor for processing electroplating seeds, with each product having a fixed focus, and professional electroplating material merchants had also emerged. Shanghai was a place where China's electroplating industry was relatively concentrated at that time.
In the old days, the electroplating operation points in Shanghai were scattered and mostly produced in a workshop style. After the founding of the People's Republic of China, some small workshops and factories were transformed and merged into state-owned or collective factories, expanding the scale of factories and concentrating production.
In 58 and 60 years, the first and second "Surface Treatment Technology Conferences" were held nationwide, promoting the development of the national electroplating industry. The development of Shanghai's electroplating industry also entered a fast lane, experiencing the "Sixth Five Year Plan" adjustment and "Seventh Five Year Plan" technological transformation. In the late 1970s to early 1980s, with the reform of the economic system, the market became increasingly active and demand tended to be rich. The electroplating industry in Shanghai reached unprecedented prosperity, in terms of economy Leading the country in technology and talent in all aspects.
The repositioning of Shanghai's urban functions since the 1980s, as well as the strategic adjustment of Shanghai's industrial layout, industrial structure, and product structure, have led to the drastic turbulence and changes in the electroplating industry. In the late 1980s, the industry economy began to decline, and for many years it has been in a slump.
With the unremitting efforts of the entire industry, industry resources have been reorganized, resulting in significant changes in economic composition, production layout, technological structure, market supply and demand, etc. In recent years, with the continuous strengthening of Shanghai's industrial economy, the electroplating industry has finally regained its upward momentum.
The economic scale of the entire industry continues to expand, attracting investment and constructing a number of advanced projects with high scale and efficiency. The overall technological level of the industry has improved, the variety of production has increased, the product level has improved, and the market space has expanded. At present, there are 381 electroplating enterprises in the city, with more than 20 plating types including zinc, nickel, copper, chromium, gold, silver, etc. The total annual output value is about 2.5 billion yuan.
