Through the 1940’s several progressively larger factories were occupied as the demand for Powermatic products grew. In 1954, the company, now run by Mr. Smith’s sons, bought land on the edge of town and built a 38,000 square foot facility specifically tailored to their operations. In 1958, Powermatic took a unique step in the industry by establishing its own 50,000 square foot foundry. This enabled the company to keep tight control on the precision and quality of its castings and to ensure that the Meehanite ™ process, still in use today, would put the company at the forefront of the woodworking machinery manufacturing process for years to come.

In 1966, the Smith brothers sold their business to Houdaille Industries. Although owned by a Fortune 500 Company, Powermatic continued to be influenced by the local community and run in autonomous fashion. In April of 1986, Powermatic was purchased and operated as a division of DeVlieg-Bullard, Inc. In October of 1999 Powermatic was purchased by WMH, who already owned Jet Tools, and Performax Products. These three companies along with the Wilton Tool Company were grouped together to form the WMH Tool Group. In 2014, Powermatic was purchased, along with its sister brands by Tenex Group and are now grouped together to form JPW Industries Inc., as they are still knowns today.
