Southwest United Industries has provided the high quality of metal finishing services for more than fifty years. Our primary goal at Southwest United Industries has been to provide finishes and related services of the highest quality at all times. We are continually seeking ways to improve our processes and services from the time we receive your part to the time your part is final inspected and shipped. Focusing on understanding our customer’s requirements and continuously working to adapt to an ever changing industry has provided us the opportunity to prosper and grow, and has provided our customers the satisfaction of knowing their parts will be completed right the first time, every time.

Southwest United Industries maintains quality system and metal finishing process approvals from all of the major prime contractors. We are constantly working to refine the processes we currently employ, and are always looking on the horizon to stay current with the latest technology. We maintain a balanced approach between production and quality. It is not just how much, but how well.

In addition to the prime contractor approvals, Southwest United Industries maintains third party certification from Nadcap. Our Nadcap certification includes AS 9100C Quality System, Nondestructive Testing (NDT), Chemical Processing (Plating/Anodize/Paint), Thermal Spray (HVOF/Plasma/Wire/Twin Arc), and Shot Peening.

An integral part of our quality systems are strict controls over the process chemistry as well as process controls. Our in-house chemists and quality engineers utilize the following equipment to maintain our processes to the consistent standards our customers expect:
