Dispensing systems for all materials
Greasing, bonding, sealing, potting and gasketing all in one
We supply components as well as 1K and 2K metering systems for greasing, bonding, sealing, potting and gasketing. All systems can be partially or fully automated or integrated into production lines. Our engineers configure your metering and mixing system according to the material being processed and your objectives.
Greasing and oiling
For the application of greases and oils, we put together the optimum system from our modular product range – from various material supply systems and pumps to metering valves, dispensing valves and process monitoring. We supply metering systems for all lubricant applications, including for contactless material application. Metering valves and dispensing valves in various forms enable dot, bead or spray application in consistent quality. Precise measuring units ensure reliable process monitoring of the metering systems and offer high reproducibility, which is particularly necessary in highly automated applications.
Bonding, sealing, potting
For metering adhesives, sealants and potting compounds, we offer various metering systems with piston, gear and eccentric screw pumps. They process low to high-viscosity materials such as epoxy, polyurethane or silicone precisely and reliably. The modular design of the metering systems ensure versatile use in all industries. The mixing ratio and the discharge quantity can be variably adjusted. A touch panel enables convenient monitoring and setting of all relevant parameters. All common systems for pre-treatment and post-treatment, such as plasma, heating and cooling, can be integrated.
Processing sealing foams and thermally conductive materials
For processing thermally conductive materials, we work with special materials and coatings that are suitable for the metering and mixing of highly abrasive materials. We specially developed dynamicLine for the dynamic mixing of polymer reaction materials based on polyurethane or silicone. It offers a reliable solution for automated series production in relation to gasketing, bonding and potting.
Are you looking for the right metering system for your application? Our experts would be happy to configure an appropriate and cost-efficient solution for you.
