About Golden West Machine.

Golden West Machine humbly began in 1982 in a small warehouse with only two lathes, one mill, and a welder. Desiring to offer a turnkey solution by combining multiple manufacturing services under one roof, GWMI sought to provide its customers with unbeatable quality, reliable deliveries, and stellar customer service. After years of dedicated determination, GWMI has grown to become a 30,000-square-foot modern manufacturing environment boasting 63 machine tools, in-house welding, grinding, and metallizing supported by a team of forty-plus highly-skilled craftsmen and manufacturing professionals.
