Surface Treatment

Glass bead blasting is a machining method in which the surface of the machined material is bombarded with hardened sodium glass beads in a stream of compressed air. The finishing is performed in closed chambers with recirculation of the working material through a closed cycle. The use of calibrated glass microbeads allows machining parts that are particularly sensitive to external influences and can't be finished with abrasives containing iron. Glass bead blasting makes the surface of the machined material matt with a "new cast" effect, which is why this method is often used to finish aluminum parts.

Sandblasting is an effective way to clean metal products with specialized equipment that delivers a pressurized air and sand mixture. For sandblasting, fine quartz sand is used to remove rust, scale and other contaminants and it creates the necessary rigid surface profile. Blasting the metal surface with abrasive particles leaves a slightly textured surface which is perfect for further application of any type of protective coatings.

Powder coating of metal is a popular technology that allows you to give the product an attractive appearance and protect the metal from corrosion. Powder coating is based on the principle of polymerization of the coating at high temperatures. The electrostatically charged powder is sprayed on the surface of metal parts then the parts are moved into a furnace where the powder particles are fused at about 200 degrees Celsius. After cooling, the polymer paint forms a very strong bonding with the surface at a molecular level. Finished products have excellent performance properties. The coating is resistant to UV radiation and does not burn out or fade over time.
