United Precious Metal Refining, Inc. (United PMR) is a global supplier of master alloys, de-oxidized sterling silver, solder and wire products for the manufacturing of Gold, Silver, Platinum & Palladium jewelry. United PMR is also a primary refiner specializing in processing all types of materials from scrap to bench grindings and sweeps.

Their success in the precious metal industry is due to exceptional levels of detail and uncompromising customer service. The technical expertise at United PMR is unparalleled in the jewelry industry.

They understand manufacturing processes and equipment used in jewelry manufacturing. Their background is jewelry manufacturing and their skills are in research and development and are supported by their state-of-the-art analytical laboratory. United PMR was granted two patents for de-oxidized sterling silver which revolutionized sterling silver manufacturing productivity. They were the first to develop a usable product, with improved formulations continuously being developed.

The United PMR Team was the first to commercialize Silicon de-oxidized gold alloys 25 years ago. Silicon de-oxidized gold alloys are the reference standard for the world, for jewelry investment casting.

United PMR's principals were the first gold solder manufacturers to substitute Indium for Cadmium in gold solders. They are very proud to have removed a very dangerous metal from many jewelry benches.

Continuing to innovate, United PMR has created SimplyWhite. The newest alloy formulation for 18K white gold creates a finished product so white, you do not need to plate it...It's SimplyWhite.

Their philosophy is simple, their success can only come from your success. They continue to strive to make your company more productive with improved products and innovative services.

The combination of their innovative master alloys, expertise in refining, and over 25 years of industry experience, it’s no wonder their customers refer to them as “Simply the Best.”

Founded in 1987 as Strickland Refining, Inc., Maguire Refining has long stood for excellence, integrity, honesty and a commitment to exceptional customer service. Owner and president, John Maguire, assumed full leadership when he purchased the company in 1993.

His son, Phillip, is now the General Manager and they employ about a dozen full-time employees in a 7300 square foot building. John often refers to his gold refinery as a place we “play with fire”. Along with the fire, they also have a state of the art Chem Lab. Maguire Refining, Inc. specializes in gold, platinum, palladium and silver refining for the jewelry and dental industries, as well as gemstone recovery for jewelers. Their mission is to provide prompt, precise returns and to complete all services in an environmentally sound manner giving customers peace of mind. Son-in-law Tom Kane has joined the business and having family work in the business offers them a chance to solve problems with shifting changes in the industry.

One of the biggest challenges the company faces is the digital age which continually decreases the use of scrap gold not only in the jewelry industry but also in the dentistry industry. The change is dynamic and can be problematic and always needs to be addressed. Maguire Refining participates in the Iowa Jewelers Association shows and the Midwest Jewelers Association events.

When not playing with chemicals and fire, John loves to swim and swims with a masters group. He competes regularly in meets and open water swimming. In 2013 he swam from Alcatraz in San Francisco Bay with about 840 swimmers and came in in 30 minutes, 1 second – a mere 1.6-mile swim! In his spare time, John is an active board member of the Midwest Jewelers Association, he cooks for “Loaves and Fishes”, Catholic Charities, and Dorothy Day Organization.  He and his son, Phillip, are avid hunters with a focus on bird hunting.
