An injection nozzle for mixing heads of reaction molding machines is disclosed which comprises a housing in which a adjustment assembly is provided for slidably moving between two adjustable stops, wherein the adjustment assembly is configured as a control sleeve which includes a pressure chamber with a movable control piston disposed therein and the pressure chamber can be impinged upon by a pressure medium, for example hydraulic fluid and wherein a first stop is provided for the control sleeve and a second stop is provided for the control plunger thereby permitting an adjustment of two operating points that are exactly reproducible, so as to prevent disturbances during operation of the molding process.

Injection nozzle for mixing heads of reaction casting machines

Process and device for manufacturing plastic parts with reinforcement

A method of and apparatus for the measurement of the degree of charging of a liquid synthetic resin component with a gas in which the flushing of the measuring column and the detection of the hydrostatic pressure are effected solely by control of the intake valve to the measuring chamber, a discharge valve at the bottom of an overflow chamber connected to the measuring chamber, and a three position valve connected to the top of the overflow chamber. In one position of this latter valve, a pressurized gas is applied to the overflow chamber to drive overflow liquid component back to the tank: in another position of this valve the column can be equilibrated with atmospheric pressure: in a third position this valve is closed.
