OUR HISTORY

Knapp MFG., INC. has a long history of quality and precision beginning with founder Fred Knapp. In 1935, he tested the limits of the Gorton engraving machine, a two-dimensional pedestal model. He engraved the “Lord’s Prayer” on a piece of gold .005” in diameter, about the size of the point of a pin. Fred Knapp started Fred Knapp Engraving Co. Inc. in 1945, specializing in steel marking stamps, engraved signs and dials. His three sons, Bob, Rich and Ray soon joined and in 1955 a new building was constructed at our current location. The company expanded its capabilities with the addition of plastic injection molding to its  engraving capabilities.

 

In 1975, Knapp Manufacturing, Inc. purchased the Fluidic Division of Johnson Controls, now known as Air Logic. Air Logic specializes in the design and manufacturing of a line of custom molded pneumatic and vacuum components such as orifice restrictors, specialty filters, check valves, pressure & vacuum switches and regulators for medical applications, industrial controls and commercial and institutional dispensing systems. Air Logic has earned a strong reputation for product innovation and excellence in customer service, providing customers with the most flexible and productive systems on the market.

In 1993, three longtime employees, Jay Haertel, John Boticki and David Horvath, purchased the company.  Since then, the business has evolved  into a Plastic Injection Molding facility while maintaining the strong reputation the Knapp family established. The company transitioned from machine engraving and is now recognized as a precision plastic injection molding & tool and die maker. Twelve additions have been completed to the original building to accommodate expanding growth.

 

In 2013, Fred Knapp Engraving Co. became Knapp MFG., INC. to better represent the business today.
