Open molds, mixing head

The high-pressure mixing head supplies the reaction mixture from a circular opening with a velocity of magnitude 10 m/s. In the runner system, the velocity can be reduced and the reaction mixture can be additionally mixed. The liquids in the gate should be directed towards the lower mold half.
