Type 2 Anodize

What is Anodizing?

 What is Anodizing?

Anodizing is an electrochemical process using a chemical bath and DC current that grows from the base as an integral part of the aluminum, creating a hard, corrosion resistant, durable oxide film.  The anodic oxide coating composed of aluminum oxide is intergrated in and on the aluminum when applied. Its porous structure allows for secondary processes such as color and sealing.

 

Applying Color

After the anodizing process has built up the aluminum oxide film, the material is pulled out of the anodizing solution.Material is rinsed in tanks with deionized water, freeing any sulfuric acid from the surface or pockets that can hold solution.Once rinsed,the material is then placed in an Organic Dye in which absorbs into the pores created during the anodizing process.Once dyed, anodized aluminum colors parts are sealed, creating a quality metal finishing.


Type 3 Anodize

What is Hardcoat?

Hardcoat is a name typically used to describe a form of Anodizing. It is achieved by running the material with higher voltages, lower bath temperatures, additives to the bath, and higher acid concentrations. This allows the aluminum oxide to create smaller, more dense pores, thus accounting for the hardness. It creates a surface that has excellent abrasion resistance. 

Colors

A true hardcoat finish always come out of the solution with a gold to bronze aluminum oxide coating. When applying a dye to the material, the material will always have a darker appearance compared to regular anodizing. Therefore, it is recommended to only apply a Black dye or sealant to a hardcoat finish.

Black Oxide

What is Black Oxide?

Black oxide is a conversion coating for steel. It adds slight corrosion resistance, and applies an even black finish for appearance. Oil must be applied in order to achieve maximal corrosion resistance. It provides minimal if any build up on tolerances.

Black oxide requires racking or fixturing a part. It is then submerged into a cleaning solution to remove any oil from the surface. Once cleaned and free of any contaminants, they are transfered over to a hot Black oxide solution, made up of sodium hydroxide, nitrates, and nitrites. The steel parts stay in the solution and convert the surface to magnetite. Once finish is reached, parts are sealed 

 Once finish is reached, parts are sealed with an  oil for corrosion resistance. 

Blast Prep

What is Blast Prep?

Blast prep, also known as sandblasting , is an operation of forcibly propelling an abrasive material against a surface to create a smooth or rough, contaminant free surface.

We offer tradition cabinet blasting and wheel blasting. We use a proprietary media which creates an even and flawless texture. Please inquire to know more about our blast finish.
