Performance Comparison In between Sandblasting Devices & Shot Blasting Machines

by Thinkall Liu Architect sandblasting machines and shot blasting machines are considered as the mechanical processing of surface treatment techniques. In most cases speaking, sandblasting devices and then shot blasting machine can both remove the rust or grease on the work piece plus guarantee the roughness requirements of the following procedure. Nonetheless, sandblasting machines together with shot blasting machines are of their own positive factors plus disadvantages. Sandblasting Devices Sandblasting devices work by compressed air to inject the sand materials on the surface of work pieces. In this way, the rust can be removed plus the surface can have certain roughness. Sandblasting is mainly used for removing the rust or oxide coating on the work pieces, especially pieces after heat treatment. sandblasting equipment can remove not just the rust, but also the grease on the surface of the work pieces. Between all the current surface treatment ways, sandblasting machines can have comparatively better cleaning effect. Sandblasting is suitable for those work pieces which have higher surface requirements. Nonetheless, the most often applied sandblasting system is made up of many original heavy sand transport devices such as scraper together with bucket conveyer. Therefore, a deep pit not to mention waterproofing layer will be needed to install the whole sandblasting system. This project involves high construction cost, huge degree of maintaining work and then high maintenance cost. What's worse, the sandblasting machines generate a lot of dust during the operation, which might result in occupational disease of the personnel around coupled with bring serious pollution to the environment. Shot Blasting Devices Shot blasting machine works by throwing the high speed running shots on the surface of the work pieces with centrifugal forces. Shot blasting machine is of much more functions compared with sandblasting machines. It can remove the rust or oxide coating, improve the roughness level of the surface, remove the burrs of the parts, eliminate the inner stress of the parts, prevent the parts after heat treatment from deforming and additionally improve the weariness resistance ability and then compressive capacity of the parts. Compared with sandblasting devices, which is mostly operated by manual force, shot blasting devices can be operated automatically or semi-automatically. The installation coupled with maintenance of shot blasting machine is also extremely simple and then cost effective. Shot blasting machine can provide perfect surface treatment to the work piece without changing its original shape together with thickness. Since shots are the main materials of the shot blasting machine, there will be no dust or any other kinds of pollution generated from the shot blasting process. Therefore, shot blasting machine is widely applied in many various industries, for instance, automobile manufacturing industry, ship manufacturing industry, steel industry and then casting industry.Read more
