China Calcium carbide supplied in barrels suppliers

Bead Blasting
In the bead Blasting machine, hitting the casting surface by steel beads, iron beads, stainless steel beads and other materials, it can remove the impurities of the casting surface and obtain uniform surface.Carbon
Sand Blasting
In the sand blasting machine and impact the casting surface with the quartz sand, brown corundum, glass beads and other materials by compressed air, which can remove the impurities on the casting surface and obtain a uniform and delicate surface.
Passivation
The casting is soaked in passivation fluid to remove impurities on the casting surface and generate an oxide film to enhance the corrosion resistance and rust resistance of the casting.The treated casting is shiny and beautiful. It is suitable for stainless steel
Electropolishing
Making the castings as the anode and placing in the electrolyte, Connecting the DC, The current solves the burrs and bulges and thus acts as a smooth polishing to improve the surface finish and increase the corrosion resistance of the casting.The treated surface is smooth and has a better luster.
Tumbling
Place the casting in a rolling roller to rub with the abrasive stone to remove impuritiesand bulges on the casting surface to obtain good surface roughness.
Mechanical polishing
Mechanical polishing is rolling action by a very thin polishing powder to remove the very thin layer of metal on the casting. Mechanical polishing includes brushed polishing and mirror polishing. The brushed polished surface has uniform filamentous lines; the mirror polished surface is like mirror. Surface roughness less than Ra0.2
Electroplating
Electroplating is the process of plating a thin layer of other metal or alloys on some metal surface by electrolysis principle. It is the process of attaching the surface of metal or other material components to a metal film to prevent metal oxidation, improve wear resistance, conductivity, reflective, corrosion resistance and enhance beauty.
Power Coating
The coating is dispersed into uniform and fine mist droplets by pressure or centrifugal force and applied on the coated surface. Coating Can be divided into air coating, no air coating, electrostatic coating
Phosphorization
Placing castings into phosphosolution, deposited on the surface to form water insoluble crystalline phosphate conversion film to prevent casting rust and have certain corrosion resistanceOur Services suppliers
