Abstract
The application relates to a mixing head including a head part and a mixing chamber device which is arranged in the head part. The mixing chamber device has a mixing chamber, which includes at least two inlets for introducing a starting material into the mixing chamber, and an outlet, via which the starting material mixture can be discharged out of the mixing chamber. A control piston is movably arranged in the mixing chamber. The mixing chamber device is releasably arranged in the head part in order to be exchangeable, wherein a transition fit and/or a clearance fit is formed between the head part and the mixing chamber device. The application additionally relates to a production method.
