Compact metering machines for cost-efficient entry into high-pressure PU processing
With its intuitive, simple usability and machine parameter configuration, the ECOPLUS series is the perfect entry to high-pressure polyurethane processing and provides an ideal alternative to low-pressure systems.
Compact high-pressure metering machines for a wide range of applications
With the HIGHLINE, Hennecke provides its worldwide users with a high-pressure metering machine for applications with two components. HIGHLINE machines impress with an attractive price-performance ratio, without compromising metering precision and foam quality.
High-pressure metering machines for metering small outputs
By opting for a MICROLINE, users will benefit from a two-component high-pressure reaction casting machine for producing components with an especially low weight. The machine design and the majority of the modules are based on the TOPLINE metering machines and are best suited for PU processing in casting and spraying procedures.
Flexible high-pressure metering machine for countless applications
Across the globe, thousands of HK machines are successfully in use in almost all fields of application. The design of the TOPLINE series comprises an easy-to-maintain arrangement of the individual units, high-quality components, and an easy-to-operate control system. In addition, the TOPLINE series offers an extremely broad spectrum of available mixheads.
Hennecke high-pressure mixheads:
Reliable technology from the market leader for top foam quality and low raw material consumption
- Modern injector or groove-controlled mixheads with single or double deflection
- Cleaning without solvents via piston or compressed air
- For the smallest shot weight up to very large outputs
The machine control system:
Equipped with many options and still easy to use
- Touch screen panel* with graphic user interface
- Illustration of flow diagram and sensor system
- Protection against maloperation
- Interfaces for data acquisition
You save so many raw materials with a PU foam machine from Hennecke
Companies that produce a lot of polyurethane products have long relied on foam machines that mix the components polyol and isocyanate using high-pressure technology. Polyurethane novices or users with small production quantities are often unaware of how efficient and cost-saving production with high-pressure component mixing is. Introducing or transitioning to high-pressure technology pays off much faster than you think, as you begin saving on valuable raw materials from day one.
The following examples show you how quickly the savings pay off. Even if you are not processing large quantities of raw materials. Here we have compared the raw material consumption of two Hennecke customers before and after the installation of a Hennecke high-pressure metering machine.
Practical example 01: Manufacturing edge protection elements from integral foam in the USA
The example is based on the following production figures:
|Work days per month: 20|
|Daily working time: 15 hours|
|Number of molds per work cycle: 1|
|Passages of the mold per hour: 47|
|Advance shot duration (low pressure): 1.0 second|
|Contents of mixing chamber (low pressure): 100g|
|Number of parts per day: 705|
|Output (g/s): 454|
|Weight per component (g): 1100|
|Raw material price of reactive mixture (USD/kg): 4.60|
Verlust durch Vorschuss und Reinigung pro Tag (kg)
