Clean dispensing of liquid silicone rubber (LSR) in medical technology, food industry and e-mobility
Special configuration enables the use of the dispensing system in the clean room
Particularly strict conditions apply to production in the medical technology and food industries. This includes that equipment has to be used in the clean room to ensure clean and sterile production. Not even the smallest particles may contaminate the end product.
In recent years, DOPAG has implemented projects for several leading European manufacturers in which the metering and mixing systems meet precisely these requirements and can be used reliably in the clean room.
Liquid silicone rubber (LSR) is used in various products in the medical technology and food industries. The silicone products are manufactured with fully automated injection molding systems. The two-component silicone is metered and mixed beforehand with a dispensing system such as the silcomix from DOPAG.
DOPAG configures all metering and mixing systems according to the application requirements. The DOPAG experts have equipped the silcomix with an electric drive rather than the usual hydraulic or pneumatic drive. This makes the metering and mixing system suitable for use in clean rooms as all components are clean, grease-free and free of material residues.
Components for blood filters and silicone baking molds
DOPAG's customers include for example a European manufacturer in the medical technology sector. The company produces blood filters and was able to simplify its production and save costs thanks to silcomix. Previously, the LSR dosing system was located outside the clean room. Thanks to the electric drive, the silcomix can now be installed directly in the clean room on the production line. The system can be monitored and operated from now on directly.
LSR metering and mixing in the cleanroom is also required in the food industry. For example, a leading European manufacturer produces silicone baking molds with LSR dosing technology from DOPAG. Here, too, the electric drive was decisive and DOPAG was the only supplier on the market that could realize the requirements.

LSR dosing in the production of e-batteries
LSR dosing systems are also used in the production of batteries for mobile energy. LSR is frequently applied to cables and electrical connections. Particularly in terms of lightweight construction, LSR is playing an increasingly important role in battery production. The electric drive of the silcomix offers another advantage here: it allows extremely precise dispensing of small amounts, as low pressure and constant speed are possible. It it not possible with a hydraulic or pneumatic drive.
The silcomix at a glance:
- Extremely low material waste through simultaneous drum drainage and use of special supply pumps (material residual quantity in drum < 1 %)
- User-friendly system operation thanks to 7” touch panel
- Precise adherence to mixing ratio through synchronous switching of piston pumps (SWIPSYNC)
- Compact, space-saving system design
- Extremely good control behavior; even small shot sizes are possible in optimal quality
- Flexible operation thanks to processing from 20 or 200l containers (on a chassis)
- Process reliability thanks to data monitoring and archiving
