The history of Hennecke Inc.

A pioneer of high-pressure technology

In the early 1940’s, entrepreneur and visionary machine builder Karl Hennecke became fascinated with possibilities and opportunities presented by an interesting new material – Polyurethanes – invented just a few years earlier. He studied the chemistry of Polyurethanes and envisioned endless opportunities for polyurethane parts in the massive reconstruction of Europe. In 1945, he founded Hennecke GmbH. He dedicated his company to the design and construction of automated processing machines that would meter and deliver in sequence the precise amount of each polyurethane raw material – Isocyanates, Polyols and other additives – to produce a specific Polyurethane system. Hennecke’s vision was to create machines that streamline Polyurethane processing by eliminating production bottlenecks and decreasing production costs, particularly by minimizing raw material waste. Soon after founding the company, Hennecke introduced the world’s first high-pressure mixing machine, an innovative apparatus that quickly injects fast-reacting Polyurethane raw materials into a mold, which allowed part manufacturers to offer their customers high-quality molded parts with performance characteristics possible only through the unique chemistries of fast-reacting Polyurethane systems.

From there, we at Hennecke never looked back. That first high pressure mixing machine was only the first success in our storied history of working closely with processors and users around the world to develop new machines and processing concepts to replace conventional materials, always with an eye to improving the efficiency and competitiveness of our customers’ processes. Prior to 1968, Hennecke served the US market from Germany. In 1968, Hennecke USA was founded in cooperation with Leon Machinery in New Jersey, manufacturing metering equipment. In 1977, Hennecke USA moved from New Jersey to Lawrence, PA, a suburb of Pittsburgh. In 2008, Hennecke USA became an independent company renamed Hennecke Inc.. Today, Hennecke Inc. continues to operate in Lawrence, PA.
