Northwestern Welding and Machine Co. was incorporated on June 21, 1976. It was originally formed to serve the navel nuclear and petro chemical valve industries by performing hardfacing and welding of valves and valve components. While continuing to still be involved in the valve industry, NWM started to diversify into the rubber mixing equipment industry in 1993. The company primarily manufactured the rubber mixer dust stops (hardfaced and machined metallic seals which prevent rubber leakage around the mixing rotors).

After extensive growth in the Rubber Mixing industry, NWM continued to expand by branching into the CNC Machining Industry. The company has experience further growth in this area over the past several years serving the Oil and Gas, High Pressure Components, Commercial Valves and Components, Oil Exploration and Rubber Mixing Industries
