A pioneer of high-pressure technology

The history of Hennecke GmbH - A pioneer of high-pressure technology

The history of Hennecke GmbH

The “Maschinenfabrik Karl Hennecke” laid the foundation for technological progress and countless important milestones within the area of polyurethane processing in 1945. Soon after the company’s foundation, Hennecke introduced the first system in the world for mixing the PU components polyol and isocyanate under high pressure – this was the foundation stone for high product quality and the efficient use of raw materials. Since then, Hennecke has worked closely with processors and users across the world to set the pace in this area. New products and processing concepts are constantly emerging to replace conventional materials and manufacturing methods. Our accumulated expertise has a direct impact on our customers’ efficiency and competitiveness.
