Abstract: A mold for forming a motor vehicle part from a polymer material comprising at least one partially overmolded metal insert having a portion intended to be covered with polymer material and a portion intended to be left uncovered. The insert comprises an overmolding limit and the mold comprises a die and a punch capable of taking different positions between: an open position for introduction of inserts and polymer material in the mold, and a molding position wherein the mold cavity is closed, the mold comprising holding means and blocking area at least one movable part and at least one projection extending over a sealing area completely including the insert overmolding limit, to prevent the polymer material from crossing the sealing area seeping between the part of the insert intended to not be covered and one of the opposite faces of the holding means and of the blocking area.

Abstract: A molding device including a mold having a stationary portion arranged on a stationary platen of a press, and a movable portion arranged on a movable platen of the press, at least one injection channel for injecting material into the movable portion of the mold, and a feeder device for feeding the mold with plastics material, the feeder device including a stationary installation including a first metering device for metering a first quantity of material. The feeder device includes at least one second metering device arranged on the movable platen, the second metering device being connected to the first metering device in such a manner as to be fed with plastics material by said first metering device, and being connected to the injection channel for injecting material into the movable portion of the mold in such a manner as to be capable of feeding it with plastics material.
