Walnut shell Grain

Walnut shell&corn cob are soft  blasting  media  processed  from natural hard fibers 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. Corn cob 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.
