Mixing and metering without any quality compromise with machine technology for every conceivable and inconceivable application: for more than 50 years, metering machines from Hennecke have been synonymous with top quality polyurethane processing and have been the centrepiece of countless processing plants. The Hennecke lineup comprises modular configurable systems for small to large outputs with first-class metering pumps, a great choice of state-of-the-art mixheads and intelligent automation.
Modular high-pressure metering machines for countless applications
Globally, several thousand HK machines are successfully in use in almost all fields of application. The machine concept of the TOPLINE series comprises a sophisticated arrangement of the individual units, top-quality, first-class components, an ultramodern and user-friendly control system and state-of-the-art mixhead technology. The current TOPLINE generation is equipped with an intelligently revised machine concept and optimised standard features.
By opting for a MICROLINE, users will benefit from a two-component high-pressure foaming machine for precisely metering very small outputs ranging from 2.5 g/s to 130 g/s. The machine design and the major part of the modules are based on the successful TOPLINE high-pressure metering machines. MICROLINE systems are perfectly suited for PU casting and spraying applications. Most typically, the compact metering machine is used in the automotive industry or spray skin applications within the advanced PUR-CSM technology. Adapted to your process parameters, MICROLINE comes with extensive standard equipment right from the factory, including frequency-controlled motors, component temperature control and an intuitive touch-screen control system.
With the HIGHLINE, we supply users with a highly efficient high-pressure metering machine for two-component applications. HIGHLINE machines impress with their attractive price-performance ratio, but without any compromise in terms of metering accuracy, adherence to the formulation, or precise compliance with part weights. The selection of top-quality components and useful additional equipment options make it worthwhile to invest in HIGHLINE machine technology for countless possible applications in the field of two-component polyurethane processing. The HIGHLINE is not just efficient in terms of costs: Every HIGHLINE series metering machine is equipped as standard with an intelligent energy-saving concept that switches any components not required to standby mode. In addition to a sophisticated automation control system, the BLUE INTELLIGENCE package also includes a combination of various additional machine components, and is thus capable of reducing energy requirements by up to 50 percent.
The machine concept of the QFOAM has been designed consistently as a series product that combines the advantages of high-pressure polyurethane technology with a convincing price/performance ratio. This ensures real added value and makes the extremely compact metering machines based on Hennecke's tried-and-tested technology an ideal alternative to low-pressure systems and their inherent disadvantages. The main uses of QFOAM machines are cold-curing flexible foam, compact systems, filling foam, integral skin foam, energy-absorbing foam and rigid insulating foam. Two QFOAM machine types are available: the QFOAM and QFOAM XL. The XL version stands out for its enhanced scope of equipment even for special applications.
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.
Slabstock foams are used when cushioning and insulating qualities combined with low weight are important. Processors who want to be competitive and conform to market requirements must be able to offer their customers high-quality products with a wide range of specific properties. Here, continuously as well as discontinuously operated slabstock systems technology from Hennecke offers the decisive advantage. The application of various technologies allows processors to achieve an extremely high degree of material yield. It is not without reason that Hennecke is the global market leader in this segment, offering a wide range of plant configurations for standard and special foams. In addition, we can also offer our customers slabstock systems technology that has been specially developed for test series and laboratory purposes.
Rigid polyurethane foam has the lowest thermal conductivity of all insulating materials and is therefore used in the form of metal composite elements in industrial and cold store construction, as well as in cooling chambers for supermarkets and in thermal assemblies for trucks. With its highly-developed continuously or discontinuously operating sandwich panel lines, Hennecke has played a decisive role in this success story right from the start. With the company Hennecke Profiliertechnik GmbH, the Hennecke Group also has a highly-specialised supplier of high-performance trapezoidal sheet roll forming systems, which can be seamlessly incorporated into the existing plant concept of Hennecke's CONTIMAT continuous sandwich panel lines. In the continuous production of sandwich elements with metal facings, Hennecke is also one of only a few suppliers that can offer its customers convincing complete solutions from a single source.
More than 150,000 tonnes of PU raw materials are processed into moulded foam parts for cars per year using Hennecke's moulded foam systems technology. Apart from seats, head and backrests, there are many other applications in which the focus is on damping, insulation and the look and feel of a material. Hennecke provides its customers with efficient system concepts for all conceivable applications and the most diverse product ideas in all kinds of quantities. Regardless of the system concept you decide on, excellent mixing quality is standard with Hennecke thanks to the sophisticated mixhead technology and first-class metering pumps.
In the manufacture of foaming lines for refrigerator cabinets and doors, Hennecke has made pioneering contributions to process and systems technology. For example, in the environmentally-compatible insulation of refrigeration appliances through the introduction of Pentane Process Technology (PPT). Today, Hennecke's refrigerator cabinet foaming lines and systems for the manufacture of insulated door elements ensure flexible implementation of a large part of the world's refrigerator production. Apart from meeting high environmental standards, the efficient systems also fulfil the strictest requirements regarding cost effectiveness, for example, due to highly efficient raw material utilisation and a comparatively low use of energy and space. Hennecke's many years of know-how in the area of refrigerator insulation guarantees the user reliable production and a faultless end product. Hennecke can also offer its customers sophisticated production systems and process technology for many other applications in the area of technical insulation using rigid polyurethane foam. These include production lines for the insulation of hot water boilers, water storage tanks and air handling units.
The innovative and forward-looking PUR-CSM polyurethane spray-moulding technology has been successful in practical use for over fifteen years now, setting new standards in PU processing ever since whether in special-purpose applications or mass production. Among users, PUR-CSM has become synonymous with efficiency, flexibility and process reliability. Supplementing the engineering portfolio of advanced spray technology, customized mixheads have been developed along with various high-efficiency processing cells and machine designs. Together, these solutions provide suitable configurations for small and large production volumes and are tailored to fit the requirements of spray technology and its special parameters.
