AB Finishing Tech

AB Finishing Tech prides itself on setting the standard for black oxide finishing, shot peening and sand blasting in the industry.  Since 1936, we have been committed to providing the highest quality finishing process anywhere, delivered ON TIME EVERY TIME!  Customer satisfaction is our # 1 priority.

Black Oxide Finishing

Black oxide is a conversion coating for ferrous materials such as stainless steel, copper, powdered materials and more.  It creates a matte black appearance which is beneficial because it adds thickness which creates added durability and stability to products.  Black oxide helps reduce corrosion and friction for the parts being treated because of the oil that is present.  This process allows the materials to be water resistant.

Shot Peening

The Shot Peening process is used to strengthen and reduce the stress profile to components. A cold working process is used to produce a compressive residual stress layer and modifies the mechanical properties of metals and composites. In shot peening, the shots dimple the surface causing compression stresses under the dimple.  The surface compression stress strengthens the metal ensuring the finished part will resist fatigue.

Sand Blasting

Sand blasting is a surface finishing process that uses a powered machine to spray abrasive particles under high pressure against a surface. It blasts the surface with particles of sand which creates a smoother and even texture.  Therefore, excess and unwanted material are worn away from the surface. Sandblasting can quickly and efficiently remove paint, rust and residue from materials.  This method has been widely used for over a 100 years.
