Bead blasting cleans and evens out the surface of your custom parts, improving the functionality and cosmetic quality. It leaves a uniform matte or satin texture on machined parts by administering high-pressure glass beads on the components. A solely cosmetic option is available on request.
| Applicable materials | Media | Cosmetic availability | Visual appearance |
| Aluminum, Copper, Mild steel, Titanium, Brass,Alloy steel,Stainless steel,Tool steel | Glass beads with grit #120 | Cosmetic upon request | Grainy,slightly matte texture. Machining marks are reduced for “non-cosmetic"options and entirely removed on primary surfaces for “cosmetic” options. |
Surface treatment is a process method that artificially forms a surface layer on the surface of the substrate material with mechanical, physical and chemical properties different from those of the substrate. The purpose of surface treatment is to meet the requirements of corrosion resistance, wear resistance, decoration or other special functions of the product. For metal castings, the surface treatment methods we commonly use are mechanical grinding, chemical treatment, surface heat treatment, and surface spraying. Surface treatment involves cleaning, sweeping, deburring, removing oil stains, and removing oxide scale from the surface of the workpiece.
Sandblasting is a shot blasting process that uses high-pressure fine glass beads to clean or finish surfaces. Manufacturers usually apply this technology to metals, plastics, glass and rubber to create an excellent surface finish. Shot blasting is a multifunctional surface treatment process that can play multiple roles during the manufacturing process, including removing coatings or corrosion, preparing the surface for coatings, eliminating appearance defects, modifying surface finish and removing surface burrs. The sandblasting process uses compressed air to spray sand particles onto the surface of the workpiece, creating a high-speed impact, thereby removing surface impurities and improving surface quality. It is widely applied in industries such as automotive manufacturing, aerospace, mechanical manufacturing, and electronic equipment
The sandblasting process is that dry sandblasting abrasives can be steel sand, alumina, quartz sand, silicon carbide, etc., but the most commonly used is quartz sand. According to the parts material, surface state and processing requirements, abrasives of different substances can be selected.
As a light finishing processing method, the sandblasting process has excellent results, especially for parts with complex shapes, such as impeller engine blades, various mold shapes (money molds, incense coins, commemorative coins molds), which are incomparable to any other method. Sandblasting polishes ceramics, diamonds, gold and silver jewelry is the most economical method.
