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. Size:6#，8#，10#，12#，14#，16#，20#，24#， 30#，32#，36#，40#, 50#， 60#， 80#，
