The hanger shot blasting machine is a casting device that uses a high-speed projectile thrown by a blasting machine to clean or reinforce the surface of a casting. The shot blasting machine can simultaneously perform sanding, core removal and cleaning of the casting. Some areas are also called sand machines and sand blasting machines.

This hanger shot blasting machine is a processing technique that throws steel grit steel balls at high speed by impact blasting on the surface of material objects. Compared to other surface treatment technologies, it is faster, more efficient, and can be partially retained or stamped after the casting process. At the same time, the hanger shot blasting machine can also be used to remove burrs, diaphragms and rust, which may affect the integrity, appearance, or definition of the part of the object. The hanger shot blasting machine can also remove surface contaminants from a partially coated surface and provide an adhesion surface profile that increases the adhesion of the coating.
