Media, Abrasives, and Consumables for Wet and Dry Blasting / Sandblasting
Consumables used in blasting process are essential components that have a direct effect on the effectiveness and performance. In order to clean, roughen, prepare surfaces for painting and coating, remove paint and coatings, deburr, strip and smooth or shape extremely rough surfaces, blasting machines and cabinets usually use these materials. Materials like glass beads, steel shot, garnet, silica sand, ceramic beads, stainless grit, brown, pink, and white aluminum oxide, corundum, fused alumina are examples of consumables. Because every material has different qualities and uses, selecting the right one is essential to getting the intended outcomes. You can prolong the life of your equipment and get more efficient outcomes faster by utilizing high-quality consumables.
Glass Beads
The spherical structure of this material makes it a preferred choice in precision processes that demand high surface sensitivity. This abrasive, referred to as glass beads, glass spheres, and glass shots, is suitable for application on various surfaces due to its non-reactive chemical properties. Glass beads are highly utilized in surface finishing and cleaning applications, particularly for cleaning aluminum extrusion dies, rubber and plastic injection molds, and for the surface treatment of medical components. They are also effective in the renovation of automotive spare parts, turbo fans, wire erosion components, accessories, fasteners, cutting tool tips, and in the removal of droplets and burrs on round saw tips.
Owing to its delicate composition, it rapidly degrades during dry blasting processes. In wet blasting, the incorporation of water effectively moderates the surface impact pressure, leading to a reduction in material breakage. Glass beads are widely recognized as a top choice for consumables in wet blasting applications.

Ceramic beads, referred to as ceramic shots, possess a spherical configuration akin to glass beads and are applicable in all scenarios where glass beads are utilized. Ceramic beads, similar to glass beads, exhibit chemical inertness, making them suitable for application on various surface types. Their reduced fragility in comparison to glass beads results in an extended operational lifespan. Although the price per kilogram is considerably greater than that of glass beads, their durability contributes to long-term cost efficiency. These applications are prevalent in the healthcare industry and in surface treatments that necessitate restoration and adjustment. Ceramic beads provide a consistent, satin and smooth surface finish when utilized in wet blasting applications, making them well-suited for this technique.
