Cartridge Case Internal and External Shot Blasting Machine | Jinwo, Qingdao, China

Jinwo's Cartridge Case Internal and External Shot Blasting Machine cleans both the inner and outer surfaces of cartridge cases and similar cartridge-type products. It removes oxide scale, welding slag and other contamination, leaving a clean metallic surface ready for painting or coating.

It is built around thin-walled cases with narrow cavities and tight precision requirements, and uses flexible clamping through the whole process so the parts are not deformed. The same approach also suits the inner or outer walls of steel, acetylene and oxygen cylinders. Non-standard customisation is available.
