The saw blade factory is mainly concentrated in China and South Korea. China's main saw blade manufacturing is mainly based on middle and low-end saw blades. In recent years, the average industry is growing at an annual rate of around 30%. The industry is concentrated in Hebei, Jiangdanyang, Quanzhou, Fujian, and Hubei Ezhou. Its downstream customers are mainly concentrated in stone mining, processing and woodworking machinery tools, especially the stone industry saw blades are expensive.
First, the current production process
The manufacturing process mainly includes cutting of the substrate, grinding of the surface and welding of the cutter head. Cutting current main processing methods, small saw blades, stamping-based, medium and large saw blades, water cutting and laser cutting, also includes the muffler cutting; currently welding technology mainly includes hot welding, high frequency welding and laser welding, among which Laser welding technology is currently the basic standard for welding processing exported by the saw blade industry.
Second, the current situation of laser cutting and welding equipment demand
In the investigation of 38 enterprise saw blades companies in Beijing exhibition in March, the industry of medium and large saw blade substrates accounted for 20%, and 6% of enterprises planning to make saw blade bases in the future, 74% of enterprise bases rely on outsourcing, and there is no recent Plan to be a base; 71% of large and medium-sized base cutting companies have laser cutting machines. Companies that plan to make saw blade substrates in the future will consider laser cutting equipment. In the survey of 8 companies that produce large and medium-sized saw blade substrates, 50% of enterprises are in the state of laser cutting equipment. From the data, it can be found that according to the current development speed of the saw blade industry, enterprises that make large and medium-sized saw blades will find a laser cutting device every two years.
According to the valid data of the welding equipment survey, 33% of the saw blades have laser welding machines, 13% of the companies are looking for laser welding machines, 13% of the companies have plans to buy laser welding machines in the future, and 41% of the companies are still I don't know what the company intends. Because laser welding technology is a technical threshold for the export of the saw blade industry, and also the water distribution collar of the high and low grades of the product, many saw blade companies have greater desire to purchase laser welding than laser cutting. Currently, companies without laser welding equipment will choose to process outside. .
Third, the development status of China's hard materials industry
The saw blade industry is a major consumer of hard materials. In 2005, although the hard materials industry suffered from internal and external problems and difficulties, it still achieved a growth rate of 26% of total industrial output value and sales revenue, which was a small slowdown and still a high-speed growth. The product structure has been significantly improved, the technical level has been greatly improved, and the production cost has dropped significantly. Due to the vicious price competition of diamond saw blades for many years, the dumping war of American anti-diamond circular saw blades in 2005 led to the rapid development of the enterprises that mastered advanced powder and indirect heating to produce diamonds, which caused the “big reshuffle†of diamond manufacturers. A large number of companies with backward technology development and failure to master this advanced manufacturing technology have been eliminated. This kind of high-speed and turbulent situation has drowned a lot of enterprises, but it has been exercised and improved as the whole industry. The sub-high-grade diamond products with the international advanced level and the largest consumption have made breakthroughs and have been put into production in batches. Ending the history of China's unique six-sided top press without producing 30/35 and high-grade products, it has aroused the close attention of international counterparts and completely changed the situation of international counterparts defying Chinese diamond equipment and technology, world famous. Two of the three major diamond companies have set up factories in China, began to purchase and research technology for diamond production in China's six-face press, and the other resold part of its diamond industry.
