Technology and Quality

Quality Assurance

Jiangsu Longfa Shot Blasting Equipment Co., Ltd. has a brand-new standardized factory building, a complete process cooperation supporting service system, a complete set of gold processing equipment and dynamic balancer and other testing equipment. In the industrial town of Xituan Town, the major industrial town in northern Jiangsu Province, Dalong shot blasting machine industrial base was the first to establish the ISO9001:2000 standard international quality management system for our products to do a good job of quality assurance.


We are an enterprise specializing in the production of shot blasting cleaning equipment and accessories integrating R&D, design, manufacturing and sales, with a registered capital of 20 million yuan and 120 employees, including 40 scientific and technological personnel. The company now covers an area of ​​about 99 mu, with a building area of ​​18,000 square meters.

Processing and Testing Equipment

The steel pretreatment line process refers to the processing process in which the steel is subjected to surface shot blasting and derusting before processing (that is, the raw material state) and coated with a layer of protective primer. Pretreatment of steel can improve the corrosion resistance of mechanical products and metal components, improve the fatigue resistance of steel plates, and prolong their service life; at the same time, it can also optimize the production state of steel surface technology, which is conducive to CNC cutting machine blanking and precision blanking. In addition, since the shape of the steel before processing is relatively regular, it is conducive to mechanical rust removal and automatic painting. Therefore, the use of steel pretreatment can greatly improve the efficiency of cleaning work, reduce the labor intensity of cleaning work and environmental pollution.

Processing and Testing Equipment

This series of steel shot blasting pretreatment line is mainly composed of roller conveyor system, shot blasting machine, automatic paint spraying system, paint mist filtration system, drying room, electric control system, and can be expanded with automatic loading and unloading system and preheating room. And can be configured according to user requirements closed-circuit television monitoring and automatic coding device. It is suitable for surface derusting and painting processes of steel plates and profiles in industries such as ships, automobiles, rolling stock, bridges, and machinery.
