Project Description


The EWIKON COOLSHOT cold-channel system ensures reliable processing of all types of liquid silicone rubbers (LSR). The innovative proven technology guarantees perfect filling of the sockets, homogeneous cross-linking due to even heating and reduced cycle times. The system is supplied complete and ready for installation of the cold half.

A new benchmark for LSR processing

  1. Filler technology with electric linear stepper motors
    Leading technology from the hot runner systems sector. Precise positioning of the valve needle. Minimised system start-up and readjustment time during production.
  2. Easy-to-maintain balanced manifold technology
    The balanced flow channels and streamlined flow channel layout allow for quick colour changes. The manifold assembly can be easily disassembled and opened for cleaning.
  3. Optimised cycle times and ideal injection points thanks to advanced nozzle technology
    Excellent thermal separation achieved by using different tip designs for water-cooled cold channel nozzles. This ensures optimised cycle times for different LSR types.
  4. OPTION: Homogeneous socket plate heating
    Heated separator plate with efficient spiral heaters and separate temperature control for each slot. Significantly more even heat profile compared to cartridge heaters.
  5. OPTION: Quick release device for removing the socket plate
    Once production is complete or in the event of a temporary interruption, it is possible to quickly separate the hot cavity plate from the cold channel nozzles. The cold-channel system is protected against LSR cross-linking.

Perfectly precise balancing of cavity filling

The tapered valve needles, combined with the high-performance electrically driven gate valve technology, enable precise control of the filling of each seat and a reliable hose seal.
