silcomix

Precise and flawless processing of liquid silicone for injection molding

The silcomix PE200 is a compactly designed, electrically driven piston pump, metering and mixing system. It is used for continuous processing of medium to high-viscosity, silicone-based media with a mixing ratio of 100:100. Metering is carried out directly from the original containers with a size of 20 or 200 l.

Features and Benefits

  • High energy-efficiency due to servoelectrically driven piston pumps
  • Simultaneous drum drainage
  • Material residues in drum < 1 %
  • Processing from 20 or 200 l containers (on one chassis)
  • Synchronous changeover of piston pumps "SWIPSYNC"
  • Pressure-controlled metering
  • Analog filling level monitoring
  • Special sealing technology for processing abrasive media (for color injection)
  • Highly comfortable system operation
  • Compact, space-saving system design

SWIPSYNC

The servo-electrical drive allows for the synchronous changeover between the piston metering pumps, independently of the current position of the related pump piston (Switching Point Synchronisation). This prevents the mixing ratio from shift ing due to diff erent changeover positions. An even drum drainage of the A and B component is granted by the needs-oriented automatic adjustment of the volume flows of the single components via the stroke speed of the piston metering pumps. At the same time, a special control of the servo drives significantly reduces the drop of the pressure and thus of the volume flow while also cutting down on the time required.
