LR-216 Polyurethane Dispensing System

LR-216 series robot is designed especially for high speed and precise three dimensional dispensing of sealants, glues or encapsulants. Robust steel frame construction with high dynamics servomotors, low backlash gearboxes and high precision tooth & rack drives on all axes provide high acceleration rates, high traversing speeds and precise contour tracking. The state-of-the-art design concept ensures to achieve shorter process time, smooth and precise dispensing.

The control system of the LR-216 uses a future-oriented industry PC technology with a real-time operating and bus system. Due to this system, no mechanical parts like hard discs or fans are required anymore. All system and program data are stored on ''compact flash'' cards. The networking and connections of external equipment can be carried out without previous parameterisation (plug&play). Onboard and remote diagnosis by modem or TCP/IP makes our service available all over the world. Modular design, innovative technology and process-reliable sequences will promote the efficiency of your investment.

The DM 502/503 is a 2- or multi-component high-performance low pressure semi- or fully automatic mixing and dosing system for gasket, gluing and potting applications of different types of parts. The DM 502/503 precisely processes liquid, medium to high viscose media such a polyurethane, silicones, epoxy resins and other polymer reaction substances.


Voltron system owners are already prepared for tomorrow's tasks as Voltron systems are able to handle different parts with new geometries and material even under changing circumstances. The 3 component version DM 503 makes it possible to process different materials simultanesously. This future oriented technology is adaptable to all Voltron precision mixing heads. Whatever the use is- either as a module n a fully autometed production line or as a stand-alone system the DM 502/503 can be integrated into any production concept.
