We provide more than 100 different types of materials and surface finishes with experience in a seamless transtion from prototype through production. Lead time as short as days.

Available Surface Finishes for You Choosing

As-machined
Our standard finish is “as machined” finish. It has a surface roughness of 3.2 μm (126 μin). All sharp edges are removed and parts are deburred. Tool marks are visible.

Bead Blasting
Bead blasting is the process of powerfully propelling, generally with high pressure, a stream of blast media against a surface to remove unwanted coating layers and surface impurities.

Anodizing
Keeping our parts in the long term, our anodizing process resists corrosion and wear. It’s also an ideal surface treatment for painting and priming, and it looks great too.

Electroplating
Electroplated coating preserves the surface of parts and resists rusts and other defects from causing decay by applying electric currents to reduce metal cations.

Polishing
Ranging from Ra 0.8~Ra0.1, polishing processes use an abrasive material to rub the part’s surface to make them shine more less shiny, depending on your requirements.

Brushing
Brushing is a surface treatment process in which abrasive belts are used to draw traces on the surface of a material, usually for aesthetic purposes.

Painting
Painting involves spraying a layer of paint onto the surface of the part. Colors can be matched to a Pantone color number of the customer’s choosing, while finishes range from matte to gloss to metallic.

Black Oxide
Black oxide is a conversion coating similar to Alodine that is used for steel and stainless steel. It is used mainly for appearance and for mild corrosion resistance.

Alodine
Chromate conversion coating, known as Alodine, is a chemical coating that passivates and protects aluminum from corrosion. It is also used as a base layer before priming and painting parts.

Part Marking
Part marking is a cost-effective way to add logos or custom lettering to your designs and is often used for custom part tagging during full-scale production.
