Abstract: The invention relates to a procedure and a mechanism for the production preferably of plastic objects with hinges (3), one-component as well as multicomponent objects, as well as the closing of these. This can take place in a single tool, as the objects are being molded in one with a turnable middle section (5) provided tool, where the in the tool finish-molded object, with the hinge (3) in an open position and with the object still placed on the turnable middle section (5), is turned further forward against a new station together with the turnable middle section (5), while or whereupon one or more for the purpose serving mechanism(s) closes the hinged object to its final position in one or more rounds before or during the ejection of the closed object from the tool. The invention e.g. can be used on a flip lid (2), which is molded together with a hinge (3) and the stationary part (1) of the object.
