Sandblasting is a type of surface processing that creates a rough texture on the surfaces of various metals (such as stainless steel, titanium, aluminum, and iron) as well as glass and wood. It removes burrs generated during the machining and molding of various metals and resins. It is particularly effective for items with complex shapes or those that are difficult to process mechanically, such as inside holes. Functionally, it is applied to improve oil retention, provide anti-slip properties, and conceal scratches. 【Features】 ■ More effective on complex shapes ■ Patterns can also be added ■ No chemicals are used ■ Matte processing can also improve slip resistance *For more details, please contact us or download the catalog.
