Surface Treatment (Finish)
Surface treatment of machined parts is an important process with a variety of purposes and methods. These surface treatment methods can be selected according to the specific requirements of the parts and the use of the environment, in order to improve performance, extend service life, improve appearance quality and other purposes. Here are some common surface treatments:
Metal Electroplating: Including Hard Chrome、Nickel、Tin、Zinc、Black Nickel Plating
Chrome Plating: For decorative and fosters heightened corrosion resistance and hardness
Nickel Plating: For enhanced decoration and wear resistance.
Hot Dip Galvanizing: dipping fabricated steel into a kettle or vat containing molten zinc.
Anodizing: Anodizing is an electrochemical conversion process that forms an oxide film,
Hard Anodize (Hardcoat): Much thicker and denser than conventional sulfuric anodize.
Titanium Anodizing: Refers to the controlled creation of an oxide film on titanium parts.
Electroless Plating: Mid Phos 、High Phos Electroless Nickel、Electroless Nickel with PTFE
Electroless Nickel Plating: A process that co-deposits a nickel-phosphorous alloy without need for an externally applied electrical current.
BLACK ELECTROLESS NICKEL PLATING: Electroless nickel plating with conductive, black
Vacuum pressure impregnation: Prevents migration of fluids or gas under pressure from contained areas
Black Oxide: Formed an integral protective surface by a chemical reaction with the iron in the meta
Phosphate: Also known by trade names Parkerize and Lubrite
Aluminum Chromate Conversion Coatings: Chemical Film on Aluminum, also called Alodine or Irridite
Titanium Nitride (TiN): Using lateral rotating cathode technology in a PVD
Powder Coating: Electrostatically charged powder onto an object,
PVD (Physical Vapor Deposition): PVD coating is deposited films on parts
QPQ (Quench-Polish-Quench): Nitrocarburizing, polishing, and post-oxidizing.
Polishing: Uses various abrasives to produce a shiny and reflective surface.
Brushing: Offers an aesthetically pleasing pattern of fine lines on a metal surface.
Bead Blasting: A process used for cleaning, polishing、deburring
Barrel tumbling: Also known as vibration polishing or vibration polishing or Barrel finishing.
Electrophoresis coating: Also known as Electrocoating, Electrodeposition, E-Coating
Passivation: The chemical treatment leads to a protective oxide layer, or passivation film,
Screen Printing: Through scraping pressure to transfer ink through the mesh to the substrate.
Pad printing: Printed steel plate, transfer the pattern on the steel plate to the substrate
