There’s a party going on in Louisville, Kentucky.

It’s a celebration of the little “Whip-Mixer” that could.

In 1919, Whip Mix created the first complete dental inlay investment casting unit – with a mechanical spatulator that whipped and mixed better than anything else. An invention so dramatic it changed the industry. And formed their company name.

It all started because a young man, Edmund Steinbock, was about to be displaced from his position at Isaac Bernheim Distilling Company at the beginning of what became a 13-year dry spell in the industry known as Prohibition.

According to Allen Steinbock’s history of Whip Mix, “young Ed met Dr. Louis C. Burgard, a dentist from across the Ohio River in Jeffersonville, Indiana who had just patented a “glorified egg beater” that whipped and mixed water together with his secret,  gypsum-bonded refractory investment and resulted in a creamy mixture that poured easily and completely around a wax pattern, set to a dense solid  and could then be burned out and cast in Dr. Burgard’s other equipment that was still being patented. The entire process was called lost wax casting which had been patented in 1907 by Dr. William Taggart of Illinois and which was becoming widely used (and copied) in the dental field.”

Edmund Steinbock and his brothers licensed the system, manufactured and presented it to dentists and through their successes reincorporated their company in 1926 under its current name, Whip-Mix Corporation, Inc.

Other products were added to the line (a tradition that continues today) and 95 years later, Steinbock descendants –along with 230 team members –develop, produce, sell and ship products around the globe.
