Finishes

RapidDirect provides surface finishes on all CNC parts, including anodizing, electroplating, bead blasting, polishing, brushing, powder coating, and painting.

Anodizing improves corrosion resistance, enhancing wear resistance and hardness, and protecting the metal surface. Widely used in mechanical parts, aircraft, and automobile parts, precision instruments, etc.

Anodizing Image

Bead blasting results in parts with a smooth surface with a matte texture. Used mainly for visual applications and can be followed by other surface treatments.

Bead blasting Image

Powder coating forms a durable, wear resistant and corrosion resistant layer on the surface of parts. Powder coating can be used to apply colors to parts and is compatible with any metal.

Powder Coating Image

Electroplating can be functional, decorative or corrosion-related. Many industries use the process, including the automotive sector, in which chrome-plating of steel automobile parts is common.

Electroplating Image

Polishing is the process of creating a smooth and shiny surface, either through physical rubbing of the part or by chemical interference. The process produces a surface with significant specular reflection, but in some materials is able to reduce diffuse reflection.

Polishing Image

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. Most commonly applied to aluminum.

Brushing Image

Painting the surface of a part improves its aesthetic appearance and can provide brand recognition to consumers. In addition, painting can have a protective effect on parts.

Tolerance

 

Standard tolerances are shown in the table below; we can work with you to achieve tighter values as needed.

 

Part size / DimensionToleranceAngularity
< 12’’ (30 mm)± .005’’ (0.125 mm)±0.5°
< 24’’ (60 mm)± .010’’ (0.250 mm)±1.0°
< 36’’ (90 mm)± 1/64’’ (0.400 mm)±1.0°

 

Tips: Tighter tolerance are examined on a case by case basis with your technical drawings.
