Servo drives engineered to ensure perfect mixing of LSR materials( as in the case of resin and hardeners, see chart bellow).

Schedding explains that there are basically three key areas of machine operation that accomplish this task, beginning with the preparation which involves ensuring a perfectly clean material inside the vessels. Servo drives control piston pumps for dosing so as to allow the manufacturer to know exactly how much is being dosed and at what speed. Finally, the mixing element utilizes a sequence of chambers to compound the material – all of which results in highly homogenous mixing.
“ This type of modular design,” remarks Schedding,“ comes from the epoxy and PU field and allows mixing anything that involves different liquids coming in at different flow rates.” In the case of PU insulation, for example, any mismatch in flow between resin and hardener creates problems. The lessons learned in working with this material were then transferred to silicone, including servo drive encoders for perfectly synchronous dosing of the two LSR
Perfect mixing of components from vessels monitored by computer, as in this case for resin and hardener.
