Glass Bead

목록보기

BrightBlast™ Glass Bead is a unique and popular air blasting media widely used for cleaning, conditioning or peening metallic surfaces. BrightBlast™ is manufactured from high-grade crushed and sized glass cullet. The cullet is melted to a spherical shape and annealed to equalise internal stresses and resist fracture. These non-abrasive, clear, transparent spheres function without particle embeddment, pick-up, contamination or other damage to the surface under trea™ent. Depending on the size and operating parameters selected, BrightBlast™ produces a surface finish ranging from fine matte to bright satin.
Decorative and special effects on surfaces may easily be achieved by masking and blasting surfaces with BrightBlast™.
The inherent characteristics of BrightBlast™ Glass Beads permit cleaning and deburring of critically toleranced parts without removing any base metal, thereby preserving the critical tolerances. In addition, the inherent strength of glass beads is such that it can survive multiple impacts, making it an ideal abrasive for use in blasting equipment fitted with recycling facilities.
BrightBlast™ Glass Beads are widely utilised in peening applications to impart a layer of compressive stresses on components exposed to cyclical loadings and containing residual tensile stresses. The use of BrightBlast™, to peen the component, reduces the risk of failure due to fatigue stress or stress corrosion cracking. Being chemically inert, and non-toxic, BrightBlast™ will not leave any undesirable or ferrous residue on blasted surfaces and uncontaminated spent media is environmentally harmless.
Industry users include Aerospace/Aviation, Automotive, Consumer Goods Manufacturing, Foundry/Die Casting, OEM Subcontractors and Semiconductor Manufacturing.
Typical applications include: Deflashing IC package lead frames; Peening aircraft engine turbine blades and other components; Decorative finishing; Surface finishing prior to anodizing or electrolytic coating; General cleaning and deburring of non ferrous components and Removal of flux residues from high temperature moulds.
 
Usage Guidelines and Performance
Bigger beads clean slower, produce higher peening intensities, remove larger contaminants, produce higher surface roughness and brighter finishes.
Smaller beads clean faster, produce lower peening intensities, remove smaller contaminants, produce lower surface roughness and more matte finish.
