The invention concerns a device for molding a plastic material article whereby the article is obtained by compressing a dose of molten plastic material (3) between two parts of a mold, comprising at least one plastic material supply (1), a rod (11) sliding in a dowel bush (8) for temporarily supporting said dose of plastic material (3), an article head mold (6, 7), a mandrel (18) co-operating with said mold (6, 7), the dowel bush (8) including an upper surface (16) and a side wall (17). The device is characterized in that it comprises means for depositing the dose on the dowel bush (1, 2) which are designed such that the amount of plastic material (22) arranged above a plane (20) coinciding with the upper surface (16) of the dowel bush (8) ranges between 20% and 40% of the total weight of the dose (3). The invention also concerns a method using said device.
