Glass Beads Blasting 100-200Micron
The gentle and versatile nature of glass beads makes them suitable for a variety of tasks:
Cleaning: They are highly effective at removing contaminants such as rust, dirt, light coatings, heat treatment scale, and welding or bending marks without harming the underlying surface .
Finishing: Glass beads are commonly used to create a uniform, attractive matte or satin finish on metals, especially stainless steel. This not only improves appearance but can also make the surface more resistant to dirt adhesion and corrosion .
Peening: The impact of the spherical beads induces a compressive stress layer on the metal surface. This process, known as peening, can significantly improve the fatigue life of metal components, making them more resistant to stress cracks and failure .
Deburring: The media can gently remove sharp edges, burrs, and feathered edges from machined parts with high precision, ensuring parts function correctly without altering their dimensions

Glass beads application—Grinding and Shot Blasting Glass Beads for Surface Treatment
1. Road marking glass beads
Can be divided into dropping on type and mixing type;
Using for roading and to raise the safety of night driving by it’s reflective performance.
Dropping on glass beads can be directly dropping on the road marks;
Mixing glass beads need to use together ;
2.Sandblasting glass beads blasting media
Mainly using for the surface sandblasting and shot blasting of metals,glass,rubber and plastics,acrylic,and can avoid the workpieces be damaged.
3. Filling/Grinding glass beads
Mainly using as filling media of weighted-blanket,plush toys,eyeshade,medical package, uniform filled and good textures
Meanwhile can be used as grinding media for paint,oil,coating,pigment,etc.
4. Precise glass beads
High precision and roundness,can be used as media for chemical ink,wine bottle cap,water pum valve,cosmetics valve,machinery bearings.
