Burr edge ,Cryogenic deburring is a cryogenic process used to remove burrs and flash from plastic and die cast workpieces. The process works by tumbling and/or abrasively blasting the workpieces at cryogenic temperature levels. The low temperatures approximately − 95 C −3 9.0 F are achieved using liquid nitrogen, liquid carbon dioxide, or dry ice.

Micronization ,In the case of grinding, the solid particles are formed when the grinding units of the device rub against each other while particles of the solid are trapped in between. Methods like crushing and cutting are also used for reducing particle diameter, but produce more rough particles compared to the two previous techniques and are therefore the early stages of the micronization process .
