Abstract
A mixing head for a reaction injection molding machine includes a body including a mixing chamber formed with an injection bore. In addition to a charging assembly for introducing at least two reactive components into the mixing chamber, there is provided a feed assembly having at least two feeds for supply of different additional components to the mixing chamber. A moveable adapter selectively and detachably couples the feeds of the feed assembly to the injection bore for selective introduction of the additional components. The adapter is constructed for rotation in relation to the mixing chamber so that an exit port of each feed is connectable with the injection bore through rotation of the adapter.
