Information on Mil-Spec Glass Bead (military specification)
Glass Bead Blasting Applications
ALUMINIUM … Deburrs, levels and smoothes: finishes, improves wear and lubricating qualities. Excellent for decorative finishes. Perfect preparation for anodizing. AD, AE or AH 280kpa (40 psi)
CARBON DEPOSITS … Glass Bead removes stubborn carbon without disturbing original dimensions of parts. AC 420 kpa (60 psi)
DESCALING … Mill, heat treat and corrosion scale can be quickly removed to provide a smooth, chemically pure surface. AD or AE 350-500 kpa (50-70 psi)
CYLINDERS … Lubrication and wearing qualities are generally improved – friction is reduced.
AC 350-420 kpa (50-60 psi)
PUMP & METER RECONDITIONING … Glass bead removes all corrosion leaving parts ready for reassembly. AD or AE 280-420 kpa (40-60 psi)
BEARINGS … Increases life… reduces wear: provides ideal surface for lubrication retention.
AB or AC 420-560 kpa (60-80 psi)
GEARS … Will not alter dimensions or damage delicate areas. Removes burrs, tool marks. Improves qualities of wear. AC or AD 420-560 kpa (60-80 psi)
CASTINGS … Cleans and levels surfaces, removes sand, no imbedment remains to complicate machine ability.AC or AD 280-42 kpa (40-60 psi)
MOULDS … Will not damage or change dimensions of moulds. Offers quick, safe removal of residual
deposits from rubber, plastic and glass moulds, no contamination, no imbedment… increased production life. AE 300-500 kpa (50-70 psi)
PLASTICS … Micro-etched surface produced by glass bead improves adhesion of paint, metal coatings, bonding and other applications. AE or AH 210 kpa (30 psi)
PLATING … Leaves no foreign matter or contaminants. Produces smooth, pure bonding surface.
AE 350 kpa (50 psi)
PRECISION PARTS … Improves wear, lubrication and fatigue strength qualities; removes burrs, no need for masking ...Glass bead performs without damage to most delicate areas.
AD, AE or AH 175-350 kpa (25-50 psi)_
ELECTRICAL PARTS… removal of oxide and varnish from motor components.
Ae 210-350 kpa (30-50 psi)
ELECTRICAL PARTS… Removal of epoxy. AB or AC 40kpa (60 psi)
STAINLESS STEEL … Surface flaws easily detected. Provides glare free stain smooth finish.
AE or AH 210-280 kpa (30-40 psi)
INSTRUMENT PARTS … Removal of corrosion on heavy or light items.
AE 175-210 kpa (25-30 psi)
VALVES … Provides controllable surface finishes, uniform operation and precision fit. Excellent for hard to reach internal areas without altering critical dimensions. Sliding and sealing contacts are greatly improved.
INDA 280-400 kpa (40-60 psi)
NON METALLIC … Matte-satin finishes on plastics, ceramics, woods, stone and other materials may be
Achieved with Glass Bead. It is especially effective in producing special decorative effects.
Variable pressure & sizes
