Users who choose shot blasting machines need to inform the shot blasting machine factory of the size, weight, output, and environmental requirements of their workpieces. The shot blasting machine factory will then provide suitable shot blasting machine models based on the information provided by the user. For example, track type shot blasting machines are suitable for batch processing of small parts, such as castings and forgings, while hook type shot blasting machines are suitable for surface treatment of castings, riveted welded parts, welded parts, and structural parts. The through type shot blasting machine is suitable for surface treatment of steel components, steel plates, and other workpieces! Also, it is necessary to inform whether to choose alloy plate or manganese steel plate for the protective plate material of the room. For example, the hook type shot blasting machine has two forms of single and double hooks, which can be selected according to the type of workpiece and production capacity.
