Why Qualtek is “the” Premier Anodizer

IHAA International Hard Anodizing Association

To be a great anodizer you must do multiple things well: process control, work order development, develop the "recipe", produce the "recipe", maintain chemistry, and manage wastewater control. Qualtek delivers high quality in each function at the same time.

Metal Finishing Explained

Finishing Department — Water Conservation Champions

Qualtek implemented a water conservation program and immediately cut its water use by more than 174,000 gallons a month. Most of the water savings came from the finishing department. Additional water savings were realized through installing a system to cool motors. Colorado Springs Utilities recognized Qualtek as Commercial Water Champions.

Customized Electropolishing Fits Client Needs

A client needed a unique finish on a medical product that was stamped at Qualtek. We suggested electropolishing for a fine smooth shiny finish. However, the part needed a matte rather than shiny finish. Qualtek developed a special solution (nick-named Willy’s Sauce) that provided just the right matte surface with the fine clean finish needed for the product.
