Our Process List
Our Processes
Plated Finishes
Precious Metal Plating
Silver plate. Bright and matte finish available.
Gold plate. Both hard and soft finishes available.
Zinc Plating
Lustrous zinc coatings can be produced over ferrous and non-ferrous metals for increased eye appeal.
Copper Plating
Primarily used as an undercoat and also for selective carborizing.
Bright Nickel Plating
Ideal as an ornamental finish for sales appeal where cost is a predominating factor.
Electroless Nickel
Assures absolute uniformity of plate inside and out regardless of irregularities of shape. RoHS compliant available.
Sulfamate Nickel
Ideal for aircraft and nuclear applications but has many industrial applications.
Tin
Used on items that come in contact with foods or in electrical field.
Bright and matte finish available.
Tin-Lead, 60/40, 90/10
Applied to parts that have to be soldered after assembly.
Our Processes
Surface Treatments
Aluminum Conversion Coatings
This coating provides a better bond and more durable protection for paint than more expensive oxide forming processes on aluminum and its alloys. RoHS compliant available.
Titanium Cleaning & Acid Etching
This is an Aerospace requirement from the OEMs like GEAE for P4TF3. Alpha-Case removal.
Zinc Conversion Coatings
A finish for zinc, aluminum, copper, brass and bronze, which protects against corrosion.
Colors include clear, blue, yellow, olive drab, or black. RoHS compliant available.
Pickling
This is a process that removes oxides from the surface of various metals, such as steel or stainless steel.
Passivating of Stainless Steel
This is a process that removes the free iron from the surface of stainless steel.
Black Oxide
This is a jet-black decorative finish for iron and steel. Has some corrosion inhibiting properties in it but is usually supplemented by a rust preventive oil. No dimensional change.
Our Processes
Anodizing
Sulfuric Anodize Type II
Provides oxide coatings for aluminum and its alloys.
Color finishes available: clear, black, red, blue, green, purple, gold, gray, and orange.
Hardcoat Anodize Type III
Dichromate and Teflon seals available.
