Corn cob are soft media processed from natural corn cob. The major advantage is that fragile components can be cleaned without marking or etching the components’ 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.
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. Corn cob is the best drying media for spotless drying, cleaning, and polishing after vibratory deburring and polishing, exhibits high absorption and cleaning qualities.
