As-machinedAs machined means the parts without any surface treatment after they get off the machines.All materialsn/aNone
Sanding and PolishingPolishing is a surface finishing process to create a smooth surface. With mechanical, chemical or electrochemical methods, polishing will reduce the surface roughness of the parts to get a bright and reflective surface.All materialsSmooth, glossy finish$$$$
Bead BlastingBead blasting use high speed jetted sand and iron shots to hit the surface of the workpiece. it will change the surface of part and improve the mechanical properties of part.Aluminum, Stainless Steel, Steel, Brass, Coppern/a$
Powder CoatingPowder coating is a surface finishing process that adhere dry powder on the surface of a meatal part.All metal materialsGlossy or Sand$$$
Black OxideBlack oxidation is a kind of chemical surface treatment. it is used for surface coating commonly because it can eliminate reflections.Steel, Stainless SteelSmooth, matte$$$
ElectroplatingElectroplating is the process of depositing a thin layer of metal matieral on metal substrate using electric current.Aluminum, steel, stainless steelSmooth, glossy finish$$$
