Solon Manufacturing Co. was founded in 1949 by four Case Western Reserve University engineering graduates: Arnold Siedle, Red Ralston, Joel Carpenter, and Bob Ramsdell. Together, they shared a vision to bring innovation to Northeast Ohio in a post-war industrialism era. Today, Solon Manufacturing Co. continues to thrive on the ideals of its founders—our passion for our company and its stakeholders has led to successful growth initiatives through new products and services.
