Process for producing a molded part

A method of producing a molded part, comprising:

• supplying a first amount of melt into a cavity of a molding tool, the molding tool comprising a first tool part mounted to a first mold clamping plate, and a second tool part mounted to a second mold clamping plate, the molding tool having a mold parting plane formed between the first tool part and the second tool part, the second mold clamping plate being movable relative to the first mold clamping plate in a direction perpendicular to the mold parting plane, the cavity having a first cavity portion in the first tool part and a second cavity portion in the second tool part, and the molding tool being configured to open and close the cavity by allowing the second mold clamping plate to move relative to the first mold clamping plate;
• during or after supplying the first amount of melt into the cavity, moving the first tool part and the second tool part away from each other in the direction perpendicular to the mold parting plane by moving the second mold clamping plate relative to the first mold clamping plate to form (i) a clearance space in one of the first cavity portion and the second cavity portion, and (ii) a gap between the first tool part and the second tool part, the gap extending parallel to a first parting face of the first tool part and a second parting face of the second tool part so as to extend an entire length of each of the first parting face and the second parting face, the first parting face abutting the second parting face to form the mold parting plane when the supplying of the first amount of melt into the cavity is started;
• and
• after moving the first tool part and the second tool part away from each other, supplying a second amount of melt into the clearance space of the one of the first cavity portion and the second cavity portion,
• wherein, after moving the first tool part and the second tool part away from each other, the gap is bridged by an at least partially solidified section of the first amount of melt.

• wherein, after moving the first tool part and the second tool part away from each other, the gap is bridged only by an at least partially solidified section of the first amount of melt.
