Abstract: The apparatus for the production of moldings, preferably of polyurethane, possesses a conveyor, which is preferably a continuous conveyor in the form of a rotary table (2), on which exchangeable molds (3) to be filled are arranged. A mixing apparatus having a mixing head (8) is provided for filling the molds, and a mold release station (5) is also present. Each mold (3) has a plug (10) which connects it to the program control unit (1) and whose contacts are set so that they select, by means of an appropriate code, the program assigned to this code. A decoder (6) translates this code and determines the corresponding program. This avoids incorrect operation as a result of incorrect program selection. Each mold determines its program itself by means of the coding at the contacts of its plug.
