Cincinnati, Ohio-based Doran Manufacturing opened in 1953 and was incorporated in 1954. The company was started by Edward Bauer and Robert Mayer and was named after their wives, Dorothy and Ann. These two men were Amp representatives who saw the need for low voltage interconnection devices like terminal boards and blocks in appliances and other machines. These blocks made the assembly of the wiring for the machine much more efficient.

In January, 1956 Doran Manufacturing Co. became a subsidiary of Osborne Coinage Company. In April of 2003, Doran became independent of Osborne Coinage and was incorporated newly as Doran Mfg, LLC. Osborne Coinage and Doran Mfg, LLC are owned by Evolving Enterprises, Inc which was formed in September, 2007 and is wholly owned by the Stegman family.

Expansion Into Transportation Safety Products

In the early 1970s, Doran applied its engineering-based problem solving approach to vehicle safety and manufactured products:

  • began producing Safety Light Monitors for school bus manufacturers in 1973
  • we also designed and built specialized PC-based fuse panels for truck OEMs (such as Peterbilt) and for RV OEM suppliers (MagneTeck and Parallax)

Tire Pressure Monitoring Systems

Doran extended the company’s transportation safety product offering in the early 2000’s with the addition of tire pressure monitoring systems for the RV and truck markets. Doran’s product development and marketing efforts propelled the company to earn the “Nifty 50: The Best 50 New Products of the Year” award presented by Heavy Duty Trucking magazine in December, 2004 which coincided with the establishment of the company as a leader in tire pressure monitoring systems for the markets they serve.

Doran 360RV™ and Doran 360HD™

To further enhance Doran’s leadership position, the company launched the next-generation Doran 360™ tire pressure monitoring systems for the RV and truck markets in early 2008. The new systems were designed for simple installation and programming and include a number of patent-pending features that addressed customer requests that have kept Doran at the top of the market. These new systems have received excellent reviews from customers for ease of use and reliability along with providing significant cost savings opportunities to truck fleets.

Doran 360 SmartLink™

Doran seized the opportunity to introduce the first tire pressure monitoring system for drop and hook trailer fleets with the introduction of the Doran 360™ SmartLink in the summer of 2008. The system allows the driver to confirm the drop or add of a trailer at a push of the button in the cab mounted display and the tire pressure data is transferred from the trailer tires.

Doran 360M™

Doran also introduced an innovative new tire pressure monitoring system for motorcycles in the first quarter of 2008. This unique system helps motorcycle enthusiasts ensure that they will have a perfect riding experience on their tires.

In early 2009, Doran developed new systems for trikes and for motorcycles with trailers due to a large number of customer requests.
