Product Detail
The finishing or the periodic cleaning of surfaces require the use of products of projection of high performance at the same time as not aggressive and that do not entail risks for the health of the operators.
Glass microspheres offer a unique combination of physico-chemical properties that can not be found in any other impact-treatment product.
It takes compressed air as the power to form a high-speed jet to shot glass
beads on surface of work-piece that causes surface and shape changes on
appearance of the work-piece. Due to glass beads’ impact effect on work-piece
surface, the surface of work-piece get certain cleanliness and different
roughness.
It improves the mechanical properties of surface so as to enhance
fatigue-resistance of work-piece.
It provides controllable rough surface for part surface to increase the adhesion
with the coating, extends the durability of the coating, and it also benefit the
flow and decoration of paints.
Provide different levels of surface effects.
1, sandblasting, painting, remove carbon,remove processing traces
2, cleaning up various molds,
3, can remove all types mechanical tensile stress, increase fatigue life.
4, semiconductor device, the tube is molded before cleaning to remove the tin
debris.
5, medical equipment, textile machinery and all kinds of metal products
finishing shot peening treatment process
6, metal tubes, non-ferrous metal precision castings cleaning and removing burrs
and debris
7, matte surface treatment of stainless steel products, the work-piece surface
scratches welding, cleaning and removing process.
8, anode oxidation and electroplating before treatment, besides cleaning
appearance, can also help increase adhesion area.
