Post-Processing 

Clean Room

Clean Room

Parts are cleaned and bagged in an ISO Class 7 (10,000) clean room to remove dirt, bacteria, and surface particles.

Paintings & Coatings

Zinc 

Most common plating. Low cost and good corrosion resistance in environments not subject to excessive moisture.

Cadmium 

A secondary dipping process after zinc/cadmium plating. This is typically used to add color for aesthetic or identification purposes.

Iridite 

A secondary coating process after zinc/cadmium plating. This is typically used to add color and additional corrosion protection.

Black Oxide

Conversion coating that does not add to part thickness. It's usually combined with oil dip, which serves as a rust inhibitor and lubricant.

Black Phosphate 

Similar to Black Oxide. Conversion coating, which is usually combined with an oil dip. 

Nickel

Nickel offers very good corrosion resistance, with a silver color that provides a more decorative appearance.

Tin 

Commonly used in the food handling industry, tin offers strong corrosion resistance against organic acids and improved lubricity.

Silver 

Enhances electrical conductivity and resists breakdown under extreme pressure and/or heat.

Galvanizing (Hot Dip Zinc)

Galvanizing applies a thick coating of zinc to serve as a corrosion protectant in harsh environments.

Passivation

This is most commonly used on stainless steel materials. Parts are dipped in nitric acid, which removes surface imperfections and produces a slight film for a bright and corrosion-resistant finish.

Anodizing

This is most commonly used on aluminum materials. Parts are dipped in acid, which oxidizes the material and leaves a hard and corrosion-resistant finish. They can be color-dipped after anodizing.

Wet Paint & Powder Coating

Wet Paint  

The coating is applied as a liquid via an evaporating solvent.

Powder Coating 

The powder coating is applied as a free-flowing, dry powder. It is typically applied electrostatically then cured under heat or with ultraviolet light.
