What is Sandblasting Treatment Finish
Sandblasting is a kind of surface treatment process.
Sandblasting is the use of compressed air as the driving force to form a high-speed jet beam to spray (copper ore, quartz sand, emery, iron, Hainan sand) with high-speed injection to the work piece surface which need to deal with, made the surface of the workpiece surfaces or shape will changes. The workpiece surface can be polished to improve the smoothness of the workpiece, so that the workpiece exposed uniform metal color, made the appearance of the workpiece looks more beautiful.
It should be noted that the profile hardness and section requirements are high for sand blasting, otherwise the profile is easy to be deformation, it would be more better to anodize or electrophoresis after sand blasting. After sand-blasting, aluminum profile can be effectively removed the mechanical pattern, welding line, coarse crystal and other defects, and with the oxidation treatment technology which can process different brightness and color of the sand profile, but also through the selection of different sizes of stainless steel pills to achieve rough or fine metal sense effect.
