Color coated board originated from corrugated iron in the early 20th century. This product, first used in garages, was produced in large numbers during World War II. In the 1950s, the United States built the first batch of broadband color coating units, and color coated panels have gradually developed rapidly in the United States, Europe and Japan.
At present, color-coated panels can be divided into two series, pre-coated panels (PCM) and film-coated panels (VCM) according to different product composite methods. The difference between the two lies in the use of thin metal plates as the substrate and the difference in surface composite materials. The surface of VCM conforms to the polymer film, and the surface of PCM is coated with polymer coating.
In the home appliance industry, the types of steel used mainly include cold plates, hot-dip galvanized sheets, electro-galvanized sheets, color-coated sheets, galvanized sheets, hot-rolled pickling sheets, stainless steel sheets and electrical steel sheets. Among them, the most consumed varieties are hot-dip galvanized sheet, cold-rolled sheet, hot-rolled pickling sheet, electrical steel sheet, stainless steel sheet, VCM coated sheet, etc.
Generally, steel products for major appliances account for about 90% of the home appliance industry, steel for small appliances accounts for about 10%, and plates account for 95% of all steel consumption. Calculated based on an average of 21 kilograms of steel per washing machine, 34 kilograms of steel per refrigerator, and 30 kilograms of steel per air conditioner, the steel consumption of the above three main products accounted for more than 80% of the steel consumption of the entire household appliance industry. According to statistics, as of 2018, the amount of steel used in my country’s home appliance industry was 12.92 million tons, a year-on-year increase of 5%.
The future development direction of the home appliance industry is industrial transformation and upgrading. Industrial upgrading puts forward new requirements for household appliance steel: high-grade, lightweight, and new requirements for steel performance; energy efficiency upgrades, increased demand for high-grade electrical steel; outdated production processes, increased demand for coated steel sheets; according to statistics, as of In 2018, the consumption of coated steel sheets in my country’s home appliance industry was 900,000 tons, a year-on-year increase of 4.65%.
1. Replacement of traditional spraying boards under environmental protection requirements
Due to multiple factors such as the aging and elimination of “post-spraying” process lines of home appliance companies, the stricter environmental protection requirements of the industry, and the rising labor cost, it has gradually become a trend for the coating process to replace the spraying process. The processing speed of the coating process is more than 10 times that of the spraying line, saving energy by 1/6~1/5, which means that the overall production cost can be reduced by 5%~10%, and the development trend is rising.
After Himei Metal’s exploration and analysis of the market, and based on the analysis of the development trend of coated steel plates, a two-way coated steel production line has been invested to produce double-sided coated steel plates. Compared with the previous unidirectional coated steel plates, two-way coated steel plates The decorative performance of the steel plate is stronger and the application range is wider.
