CNC Finishes

Finishes and Post-Processing Options

We offer several finishing options for zinc CNC machined parts.

  • Anodizing: This process forms an oxide layer on the surface of the zinc part, allowing for color customization.
  • Electroless nickel plating: Coats the part with a nickel-phosphorous alloy, making it resistant to corrosion and wear.
  • Powder Coating: Coats the part with a layer of polyester or epoxy powder, providing a durable finish.
  • Passivation: A chemical treatment that removes impurities from the surface of the zinc.
  • Hot Isostatic Pressing (HIP): A process that reduces the porosity of the zinc and improves its mechanical properties.
  • Chromate Conversion Coating: This process adds a thin layer of corrosion protection and an appealing finish.
  • Electroplating: This process coats the zinc part with a thin layer of metal (such as gold, silver, or copper), providing an attractive finish and additional corrosion resistance.
  • Hot Dip Galvanizing: This process involves dipping the zinc part into a vat of molten zinc, forming a protective layer on the surface that prevents rust and corrosion.

Applications & Industries

Our machining capabilities allow us to work with zinc to fabricate parts for a broad spectrum of applications, including:

Automotive components (gear boxes, car handles, etc.)

Pumps and valves (valve bodies, valve stems, etc.)

Hydraulic and pneumatic parts (cylinders, actuators, etc.)

Industrial and military hardware (locks, brackets, etc.)
