The invention relates to a press making it possible to manufacture a one-piece object, such as a tube, and to the method for using said press. This object is made up of a first part, for example a skirt, of a second part, for example a hinge cap and of a third part, for example a dispensing head, this third part being overmoulded on the other two. The press comprises two rotary plates (110, 210) which are parallel but offset, each one carrying a mould (120, 220) in two parts (121, 122; 221, 222). Each mould part can be placed by rotation means either at the top or at the bottom, so that the mould part (121) of the first mould, situated at the top, faces the mould part (222) of the second mould situated at the bottom. According to the method, the first parts are inserted in the press in a first region, known as the insertion region (Z1). At the same time, the second parts are introduced into a second region known as an introduction region (Z2). In a third region (Z3), known as a common region, the third parts are overmoulded on the first parts and the second parts previously positioned in an insertion region and the introduction region and brought into proximity with one another in the common region in the position that they will occupy in the finished object. After stabilization and partial cooling, the press is opened, the plates are turned so that the finished objects are situated in the mould part of the second part which is at the top, while the first parts are situated in the mould part of the second mould which is at the bottom and the second parts are situated in the mould part of the first mould which is at the top. |
