One key factor that ensures high-quality and efficient processing of polyurethane is mixhead technology. The development and manufacture of high-pressure mixheads requires a great deal of know-how and many years of experience. Hennecke has outstanding expertise in this area and makes its mixheads (apart from a few standard parts) in its own manufacturing halls. This is a novelty in the European competitive market. It is also the reason why many leading PU processors prefer mixheads from Hennecke. They know from experience that the high-quality design pays off in the production process.
Whether rigid or flexible, integral skin, filling or energy-absorbing foam is concerned, Hennecke has the the appropriate high-pressure mixhead for almost any application, that requires mixing based on the impingement injection principle, from standard to specific applications. Hennecke offers high-pressure mixheads of variable sizes and injector shapes, featuring a comprehensive range of accessories, to suit almost any imaginable application – including yours.
MT mixheads are the most recent addition to Hennecke's mixhead portfolio. Their fundamentally new design sets a new standard in high-pressure polyurethane mixing technology. This innovation can help you optimize your processing results with all common PUR systems. Hennecke MT mixheads can...

For some raw materials and applications, it is not possible to mix them efficiently or effectively through the impingement injection principle. Casting systems or high-viscosity components are two examples. For processing many reactive components and additives, such as in continuous slabstock lines, mixheads are fitted with special stirrers to ensure that the reactive systems and additives are mixed homogeneously in the mixing chamber and a laminar output is achieved. To a certain extent, processors can influence the cell structure and cell size of foaming systems through the use of particular types of stirrers. High-strength stirrers are used in compact and cellular elastomer systems, ensuring optimal results even when blending is extremely difficult.
MEL mixheads are provided standard with hydraulically controlled mixhead injectors to facilitate extremely short and synchronous switching cycles. This is a novelty that guarantees you superior metering quality. Moreover, MEL mixheads are also fitted with a sophisticated mixing chamber and...
