The surface specialist KST Kugel-Strahltechnik uses glass beads to remove machining marks, contamination and weld discoloration. Since many components from the food industry and container construction - or even stainless steel objects - react to blasting media containing iron, this is a sensible alternative. KST's glass microspheres clean safely and reliably, protecting the surface and producing a satin finish.
"The result is extremely uniform - we achieve an absolutely homogeneous surface with glass bead blasting. Another major advantage is that the microspheres do not trigger any chemical reaction with other materials and do not cause any corrosion on the component or workpiece," explains KST Managing Director Marco Heinemann. At 6 on the Mohs scale, i.e. around 800 HV, glass spheres are a relatively hard and efficient abrasive. And yet gentle: Their spherical shape reliably prevents damage to the surface.
