what is Bead Blasting？
Bead blasting is a precision surface treatment process that projects uniform-sized media (such as glass beads, aluminum oxide, or ceramic beads) at high pressure onto workpiece surfaces, creating uniform micro-indentations to achieve specific surface effects. This technology is widely applied to surface treatments of various metallic and non-metallic materials, effectively enhancing product performance and aesthetics.
