Individually configured metering technology

Absolute precision, reliability and reproducibility – the technical requirements within highly automated production processes are constantly growing. This places high demands on metering technology, as it is used in practically all industrial applications and industries, ranging from greasing components in the automotive industry, bonding and potting electronics, to the application of gaskets in the packaging industry.

We support companies from a wide range of industries in this development and help them to achieve long-term success with innovative metering technology. Key to this is the individual configuration of the metering and mixing system. The only way to guarantee stable production is to have a system that is tailored precisely to the application and material. Our experts will therefore examine your request thoroughly and go through all the details with you individually. If required, our engineers can carry out material tests, sampling and detailed consultations in our own technical centre. The result is a metering system tailored precisely to your specific needs. Our customers include operators of metering systems, system integrators or other manufacturers of metering and mixing systems who are looking for the highest level of quality and precision in their metering systems.

The right metering technology for every application
We supply components as well as 1K metering systems and 2K metering systems for all applications from a single source. Our metering technology is suitable for greasing, bonding, sealing, potting and gasketing. Our systems process one- and two-component materials. This includes the metering of lubricants, polyurethanes, epoxy resins or silicones with various properties. Our metering systems are suitable for low to high-viscosity materials as well as for pasty and abrasive media. We also offer a wide range of components, which can be put together in a modular way. This includes drum pumps and barrel pumps or pressure tanks for material supply. Dispensing valves and metering valves enable the precise application of lubricants, adhesives and sealants. Various components for testing and control guarantee high product quality and reproducibility.

We use piston, gear or eccentric screw pumps for metering and mixing two-components materials. Close interaction with automation enables component feeding, pre-treatment and application in one go and without the need for user intervention. The product range includes individual and line-integratable production cells as well as individual solutions.

Consistent global standards in metering technology
We have extensive expertise in mechanical and plant engineering and have been manufacturing in the industry since 1976. We are continually developing our products and we set the highest standards for the quality of our metering systems from the production stage. We work closely with material manufacturers and have carried out over 3,000 projects in around 70 countries in the last ten years alone. Thanks to our worldwide sales and service, you can implement your specific metering system across all of our sites. With our own subsidiaries and partners, we have a local presence in more than 40 countries, ensuring that your individual system can be implemented uniformly at your production sites throughout the world. Our Service team also provides specific, reliable support with preventive maintenance, repairs, training and replacement parts.
