Surface Finishing Options We Offer
Improve appearance, durability, and performance with the right surface treatment.
As-Machined
Parts are delivered right after CNC machining, with visible tool marks and sharp edges. Fastest and most cost-effective finish. We can deburr edges if needed.
Anodizing (Type II / Type III)
Mostly used on aluminum parts. Improves corrosion resistance and adds a clean, professional appearance. Type II offers color options; Type III (hard anodizing) adds durability.
Black Oxide
Creates a dark, matte finish on steel. Provides mild corrosion resistance and reduces glare. Often used for shafts, gears, and fasteners.
QPQ (Quench-Polish-Quench)
A nitriding process for steel parts that improves wear resistance, surface hardness, and corrosion protection. Often used in automotive and tooling components.
Zinc Plating
A thin coating that protects steel from rust and gives a shiny or matte finish. Ideal for fasteners, brackets, and hardware.
Bead Blasting
Gives parts a smooth, matte texture by removing machining marks. Ideal for uniform appearance and product housings.
Electropolishing
Removes a thin surface layer from metal to improve brightness and smoothness. Commonly used for stainless steel to reduce friction and enhance cleanability.
Tumbled (optional)
Used to remove burrs and sharp edges on small metal parts. Improves handling safety and gives a soft, matte finish. Suitable for bulk finishing.
