Irwin Research and Development is located in Yakima Washington in the United States. All of our facilities are housed in a multi-building complex, in a common industrial park. A new building in 2005 will add 34,000 square feet to our complex. The company's largest investment lies in the machine shop which features numerous modern CNC machining centers, plasma arc stations, EDM machines, grinders, welding facilities, etc. The machine shop produces all the manufactured components for the thermoformers, "Chesaws", and tooling sets.
