Product Description:
Surface Finishes options
You can choose a wide selection of metal surface finishing services
after machining at ZCM CNC machining manufacturer to improve the
parts appearance, surface smoothness, corrosion resistance and
other performance of your CNC machined parts.
Painting: refers to an altering surface finishing process, spraying paint,
pigment, or color to a solid surface as a colored protective layer,
and can be done on metal or non-metal CNC machined components of
any shapes, usually applied on aluminum, stainless steel and steel
alloy parts. The purpose is to improve aesthetic appearance and
prevent corrosion or oxidation.
Passivation: a common chemical surface treatment method for steel and stainless
steel, to remove ferrous contaminants or use a light coat of
protective material to create a shell for enhancing the corrosion
resistance or reducing the chemical reactivity.
Electroplating/Plating: a process of using an electric current to reduce dissolved metal
cations so that they form a thin coherent metal coating on an
electrode, to change the properties of the metal surface or build
up thickness for undersized parts.
Powder coating/Powder coat: a functional and decorative finish, which is applied as a
free-flowing, dry powder, employs electrostatically and then cured
under heat, to create a hard finish that is tougher than
conventional paint. The main applications including household
appliances, aluminum extrusions, drum hardware, automobile,
motorcycle, and bicycle parts.
Anodizing/Anodized: an electrolytic passivation process of forming a thin layer of
aluminum oxide on the exterior of aluminum CNC machined parts to
increase the thickness of the natural oxide layer and protect the
metal, as the layer has higher corrosion and abrasion resistance
than aluminum.
Polishing: also known as buffing, a process of rubbing the surface of parts
or utilizing a chemical action to produce a smooth and shiny
surface, make the surface get significant specular reflection or
reduce diffuse reflection in some materials.
Black oxide: also known as blackening, gun bluing or hot blackening, a chemical
process of forming a black conversion coating on stainless steel,
copper and copper based alloys, zinc, powdered metals, silver
solder, and ferrous materials, to improve corrosion resistance and
minimize light reflection.
Conversion coating: also known as chromate conversion, the coating is used for metals
converted to a protective layer through the chemical or
electrochemical processes, primarily used as a corrosion inhibitor,
decorative finish, or to retain electrical conductivity.
Bead blasting/Bead blast: the process of removing surface deposits by applying fine glass
beads at high pressure without damaging the surface.
Abrasive blasting/sandblasting: the process or operation of propelling a stream of abrasive
material composed of high-velocity sand-sizes particles against the
metal surface under high pressure with blast equipment like an air
pressure system, to remove surface contaminants, clean metals or
increase a texture, then change the smoothness or roughness of the
surface.
CNC Lathing also provides grinding, linishing, industrial etching,
and more custom metal finishing service for presenting the best
effect of your part.
