ABSTRACT:
A mixhead for a reaction injection molding machine utilizing at least two liquid components supplied under pressure from a delivery system including a recirculation line. The mixhead comprises a housing having a longitudinal channel through the housing and a ram fit with a close slide fit in the channel. The ram is reciprocable from a first upstream position to a second downstream position. A first inlet port extends through the housing into the channel. A first exit port extends from the channel through the housing upstream from the inlet port and on the opposite side of the channel. At least one other similar inlet and outlet port is provided, each spaced peripherally around the channel from the first inlet and outlet ports. Spaced apart recirculation passages extend through the ram to connect the respective inlet and outlet ports when the ram is in its second downstream position.
