The present invention relates to a mixing machine configured to receive a receiving device in order to form a manufacturing apparatus, the mixing machine comprising:



a support defining a receiving housing, able to receive a receiving device, the receiving device being configured to receive first and second capsules containing respectively a first formulation and a second formulation, the two capsules being fluidly linked to each other,
an actuation system, movable inside the receiving housing to exert a pressure force on the receiving device and/or on the first and/or the second capsule(s),
a retention mechanism, movable relative to the support and configured:

in an insertion position, to authorize the insertion and the withdrawal of the receiving device into/from the receiving housing, and
in a retention position, to block the withdrawal of the receiving device from the receiving housing.
