There are many different types of castings, so the selected shot blasting machine is also different. The following are the general principles for selecting a shot blasting machine for castings:


1. The characteristics of castings (size, quality, shape and material, etc.), the size of the production batch, the types of castings and the requirements for use are the main basis for choosing a shot blasting machine;


2. The determination of the shot blasting machine should be considered in conjunction with the production process before cleaning. The surface of the casting should be cleaned after falling sand as much as possible to create favorable conditions for cleaning. When using the shot blasting process, in mass production, the falling sand and surface cleaning are suitable for two processes, which are carried out on two equipment;


3. For investment castings that are difficult to shake out with a sand shaker and castings with complex cavities that are difficult to core out, electro-hydraulic sand cleaning can be used; for castings with complex, narrow cavities and high cleanliness requirements, such as hydraulic parts, Valve castings, easy to use electrochemical cleaning;


4. For multi-variety and small-batch production occasions, cleaning equipment that is adaptable to the size of castings or equipped with two types of carrier devices should be selected; for small-variety and large-volume production occasions, high-efficiency or special shot blasting cleaning equipment should be selected;


When dry cleaning and wet cleaning can meet the cleaning requirements, dry cleaning that does not produce sewage should be selected first; in dry cleaning, first consider a shot blasting machine with high efficiency and low energy consumption; for complex surfaces For castings and inner cavity, according to the size and production batch of castings, squirrel cage type, manipulator type, and hook type which can swing or move during cleaning can be selected as shot blasting machines.
