Abrasive blasting, is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface or remove surface contaminants. A pressurized fluid, typically compressed air, or a centrifugal wheel is used to propel the blasting material. There are several variants of the process, using various media; some are highly abrasive, whereas others are milder. The most abrasives are shot blasting (with metal shot) and garnet blasting (with garnet). M Tech committed to develop timely with new technologies eco-friendly blasting using closed cabinet and wheel blast machine with 0% dust steel grit.
