Glass Beads
Glass Beads will clean metal parts without etching the surface. Glass Beads are commonly used for automotive restoration, polishing of castings, stainless steel fabrication, and light deburring of precision parts. Glass Beads are most commonly used in abrasive blast cabinets. Its round shape gently cleans metal parts, leaving a smooth, polished or matte finish.
Low Dusting
Glass Beads are typically blasted at 60-90 PSI to achieve the most productive results. This lower PSI, along with glass bead's durability, produces lower dust levels than most mineral or slag abrasives. Low dust levels improve the operator's visibility of the work surface, increasing production rates. Lower dust levels also reduce cleanup costs on the work site.
Recyclability
Glass Beads are an environmentally-friendly and clean abrasive that is aggressive enough to clean and deburr parts, yet will not damage them. Glass beads can be recycled up to eight times or more. Abrasive blast cabinets provide the best recyclability rate.
Application Flexibility
Glass Beads can easily perform a wide variety of abrasive blasting jobs. Larger sizes can be used for the cleaning of automotive parts, castings, and deburring rough edges from castings and gears. Medium sizes are suited for blending surface defects and working with aluminum and stainless steel parts, providing a satin to matte finish. Fine sizes work best for light duty work and allow for fine detail work.

Application for sandblasting
1.Sandblasting for rust,paint,carbon removal and remove the machining marks.
2.Used for cleaning all kind of molds, rubber mold except the cleaning and rust removal for off line cutting mold of parting release agent.
3.Cleaning all kinds of mechanical tensile stress to increase fatigue life.
4.Cleaning to remove the burrs before tinning for semiconductor device,plastic tube.
5.Shot peening strengthening for medical apparatus and instruments,textile machinery and kinds of hardware products.
6.Cleaning and removing burr residue for kinds of metal tube and nonferrous metal precision casting
7.Surface polishing treatment for stainless metal products, workpiece welding cleaning and surface scratches removal processing
8.Anodising and the process before plating,in addition to clean the appearance this can also increase adhesion area.
Glass Beads For Road making:
Transparent spherical glass particle, used to provide night visibility for road markings by reflecting the incident headlight beams of a vehicle towards the driver.
Reflecting glass beads play a crucial role in maintaining visibility of motorist for driving under dim light or bad weather. They are widely used in highway and airport runway and other pavement transportation systems such as zebra crossing in urban traffic road,cut off line,double amber line road marking etc as reflective materials.
