Abstract:
1. A process for the production of an article made of moulded plastic material with a first moulded component and at least one second moulded component overmoulded on said first component, said process including: a first step of injection moulding of the first component and a subsequent step of injection moulding of the second component for overmoulding thereof on the first component, in which said first and second injection steps are carried out within a moulding cavity defined between a first mould surface and a second mould surface that are mobile with respect to each other under the action of a closing pressure, wherein in said second injection step for overmoulding said second component, said moulding cavity is at least in part delimited by at least one resting surface of a mobile element which is independent of and mobile with respect to said second mould surface and in contact with said first component; pressing said resting surface solely to the first moulded component by the action of a pressing means coupled to the second mould surface for setting at least one mobile element; wherein an applying force is independent from the closing pressure and applied only along a portion of the first moulded component; avoiding pressing with the force on the second moulded component; and wherein at least one mobile element moves aside of the second moulding cavity when the resting surface applies the force only along the portion of the first moulded component.
