Walnut Shell & Corncob are soft blasting media processed from natural hardfibers of walnut or corn. The major advantage is that fragile components can be cleaned without marking or etching the components' blasted surfaces.

They are suitable for cleaning autoMobile super chargers and turbine blades, removing unwanted flash residue produced during the moulding process from semi-conductor integrated circuit package lead frames without damaging or pitting the package surface. They are also used in power generation stations, turbine overhaul factories and the aerospace industry.

Besides these, walnut Shell is widely used for cleaning moulds, motor armatures and motor drives prior to rewinding. Corncob is very light, soft and absorbent. It can be used for cleaning delicate surfaces or brass/brick/stone/wood, engines and engine components as well as mass finishing processes for drying and absorbing water, oil or wax from processed parts and also for fine polishing or brightening of parts.
