Hook Type Shot Blasting Machine
As a key equipment in industrial surface treatment, hook-type shot blasting machines play an irreplaceable role in various fields with their unique structural advantages and strong adaptability. Its core working principle is to hang workpieces through hooks, drive them to rotate 360 degrees in the cleaning chamber, and use high-speed shot projected by the impeller to treat the workpiece surface comprehensively. It is mainly suitable for the surface treatment of various medium and large castings, forgings, weldments and heat-treated parts, including fragile and irregularly shaped workpieces. It is applicable to the surface cleaning or strengthening of multi-variety, medium and small batch castings, forgings and riveted weldments, and is especially suitable for the surface cleaning or strengthening of collision-sensitive slender and thin-walled parts. It can exert strong shot blasting on the surface of steel in its original state, remove rust spots, welding slag and oxide scale on the surface, so that it can obtain a surface with uniform finish and consistent metallic luster, so as to remove stress and improve the surface coating quality and anti-corrosion performance of steel.
In terms of Experience, after years of technological practice and market verification, the hook-type shot blasting machine has formed a mature technical system and rich application experience. Manufacturers in the industry have continuously optimized equipment structure and performance based on the characteristics of different workpieces. For example, aiming at fragile and irregular workpieces, they have improved the hook hanging method and shot projection angle to avoid workpiece damage during the treatment process; for slender and thin-walled parts that are easy to collide, they have adjusted the shot speed and density, and added a buffer protection device to ensure the treatment effect while protecting the workpiece integrity. In addition, enterprises have accumulated rich debugging, operation and maintenance experience, established a complete after-sales service system, and can provide targeted technical guidance and maintenance services according to the actual needs of customers, solving various problems encountered in the use process and ensuring the stable operation of equipment. The continuous accumulation of these practical experiences has laid a solid foundation for the upgrading of hook-type shot blasting machines and the expansion of application fields.
In terms of Markets, driven by the upgrading of the global manufacturing industry and the increasing demand for surface treatment quality, the market of hook-type shot blasting machines has maintained a steady growth trend. According to industry statistics, the scale of China's shot blasting machine market reached 6.85 billion yuan in 2025, of which hook-type shot blasting machines accounted for about 35%. Domestically, the industrial clusters in Jiangsu, Shandong and Guangdong contribute more than 75% of the national output, and the demand in construction machinery, automobile manufacturing and steel structure fields is growing steadily. Internationally, domestic hook-type shot blasting machines are favored by customers in Southeast Asia, Russia, Mexico and other regions due to their high cost performance and strong adaptability, and the export volume is increasing year by year. At present, with the tightening of environmental protection policies and the trend of intelligent transformation, energy-saving, low-dust and intelligent hook-type shot blasting machines have become the mainstream of the market, and the market space for high-end customized products is constantly expanding.
In the future, with the continuous accumulation of technical experience and the continuous upgrading of market demand, hook-type shot blasting machines will further develop towards intelligence and customization, continuously optimize product performance, expand application scenarios, consolidate the domestic market position, and actively explore the international market, so as to achieve higher-quality development in the global surface treatment equipment market.
