DoskoSil: Mixing and Dosing Liquid Silicone Rubber
The VOGEL mixing and dosing system DoskoSil for the continuous mixing and dosing of liquid silicone rubber (LSR), 2K adhesive materials and 2K epoxy systems processes even abrasive materials up to a viscosity of 500,000 mPas. As standard, the equipment is capable of feeding the material from 20 l and 200 l barrels. The components are filled into the mould by means of two independent hydraulically powered double-acting plunger pumps through a static mixer.

Dynamically Prepared |
The dynamic material degassing unit is the optimum solution for the degassing of low, medium and highly viscous liquid silicone rubbers (LSR). The special design allows the material to distribute on thin, permanently renewing layers. This technology ensures an efficient and high-quality material preparation – especially when manufacturing high voltage components.

|
Independent of Viscosity |
The VOGEL LSR mixing and dosing system type DoskoSil contains hydraulically powered double-acting plunger pumps to ensure a uniform material flow, constant mixing ratio as well as precise filling speeds and filling volumes for highly viscous materials and components with different viscosity.
|
|
Efficiently Vented |
Fully automatic venting of the follow-up plates and fully automatic purging of the double-acting plunger pumps grant thorough venting after a barrel exchange with minimum material consumption and without impact due to operator faults. So, both error rate and material waste are reduced.
|
|
Freely Programmable |
The purpose-developed DoskoSil control and software provide highest flexibility in selecting the filling profiles. Up to 30 predefined filling processes are freely programmable and can supply up to four consumers at the same time. Communication with the clamping unit or the mould carrier is effected via several interfaces of the integrated control.
