N.R.M. Gearboxes And Transmissions

NRM Transmission Services provides some of the most widely used extrusion service Gearboxes for the plastics industry. NRM was one of the first companies to produce plastics extrusion equipment in the United States of America. The company was known a National Rubber Machining Company and began to produce manufacturing solutions for the plastics industry in the early 1900s. NRMs expansion was due to the success of all the plastic extrusion equipment they were producing and by manufacturing for multiple industries including piping, tubing, sheet, cast film, blow molding, reclaim, recycling, pelletizing, compounds, wire and cable. In 1994 National Rubber Machining Co was purchased by Davis Standard Extrusions Systems and the NRM Brand name was retired. Although there are no modern NRM Gearboxes on the market today, NRM Machinery is still being utilized across the industries as a testament to the quality of the brand.
