About

BIMAC is a premier source in the Midwest for Osborn-Shaw process ceramic castings and precision investment lost-wax castings, serving customers around the world. BIMAC can provide a high variety of complex castings for machinery components in proprietary wear-resistant alloy’s up to 300 pounds in individual component weight, in over 100 different metals.

In the 1950’s Dr. William Schneble, “Bill,” earned his Bachelor’s Degree in Chemistry from the University of Dayton, then a Doctorate in Science specializing in Metallurgy from the Massachusetts Institute of Technology (MIT). His future partner Dr. Clyde McQuiston, “Mac,” earned his Bachelor’s Degree in Aeronautical Engineering from Purdue University, then his Doctorate at Ohio State University, while teaching foundry practices. These two men were aggressive in their thinking and were determined to start a state-of-the-art foundry.

BIMAC was founded in 1959 in the historic manufacturing region of Dayton Ohio. The name is derived from combining the two original owners’ names “Bill & Mac.” They recognized an opportunity to bring innovation to the metal casting industry and purchased a licensing agreement from Shaw Corporation to use the ceramic mold process new to the U.S. at the time, which was originally patented in England in the 1930’s. BIMAC’s original building was on Montgomery Street in Dayton.

By 1967, business had grown to the point of needing a larger facility, and BIMAC moved into our current location at 3034 Dryden Road in Dayton. During these early years, the majority of BIMAC's business was making ferrous and non-ferrous castings for local General Motors plants, machine shops in Dayton, and various manufacturers' assembly lines. As business continued to grow, BIMAC began producing castings for many different industries, including Aerospace & Defense.

In the 1970’s, future owners Dan Bizzarro and Bill Jordan started working at BIMAC while still in college. Upon graduation, they joined full-time in manufacturing and engineering roles. Roger Reedy joined BIMAC in 1973.

In 1980, the Dryden Road building was expanded to add investment casting lost-wax process. In 1986, Bill, Dan, and Roger took ownership of the company. Over the next two decades, non-destructive testing and machining facilities were added, then later closed, as markets and local manufacturing suppliers evolved.

In the 2000’s proprietary wear-resistant alloys for special machinery markets were developed with local technical resources such as Wright-State University in Dayton. BIMAC casts proprietary wear-resistant materials used in thin glass for electronics, recycling equipment, chemical processing, food machinery, pharmaceutical manufacturing, and corrosion resistance pumps for example.

In 2017, BIMAC was acquired by Ventoux Industrial Holdings, a broad-based manufacturing and industrial holding company with a team-oriented approach to bring the highest and most long-term value to companies and employees. After the acquisition, benchmarking, and strategic planning were performed to ensure the right investments, technological capabilities, and automation are in place to maintain customer relevancy and continued success into the future.

As a member of the Investment Casting Institute and Dayton Regional Manufacturing Association, BIMAC is proud to have celebrated its 60-year anniversary and continue to provide high-quality castings. Today, we remain a vibrant company in Dayton Ohio’s historic manufacturing region.
