Post-Processing
Surface Finishes
Protect, harden and beautify your machined parts with 12 proven finishing processes.
Surface Treatment Options
Hover any finish to see it up close. Every finish is applied under controlled process parameters and verified before shipment.
As Machined
Supplied directly after CNC machining with visible tool paths. Ideal for prototypes, fixtures, and functional parts where cost and lead time matter more than cosmetic appearance.
Anodizing
Electrochemical treatment for aluminum that forms a protective oxide layer to improve corrosion resistance, appearance, and wear performance.
Bead Blasting
Uses fine abrasive media to create a clean, uniform matte or satin texture on metal surfaces.
Black Oxide
Chemical conversion finish for ferrous metals that creates a dark, low-reflective surface with minimal dimensional change.
DLC Coating
Thin, hard coating selected for low friction, wear resistance, and reduced surface adhesion.
Electropolishing
Electrochemical process that smooths microscopic irregularities, improves cleanliness, and enhances corrosion resistance.
Heat Treatment
Controlled heating and cooling process used to improve hardness, strength, wear resistance, or dimensional stability.
Nickel Plating
Deposits a uniform nickel layer for corrosion resistance, wear resistance, and a bright metallic appearance.
Gold Plating
Electroplating process that deposits a thin and durable gold layer for excellent corrosion resistance, conductivity, solderability, and premium appearance.
Powder Coating
Applies a dry powder and cures it into a durable protective layer with strong corrosion resistance and decorative color.
PVD Coating
Vacuum-deposited thin coating used to improve hardness, wear resistance, friction performance, or appearance.
Zinc Plating
Applies a sacrificial zinc layer to steel or iron parts for cost-effective corrosion protection.
