Patent ID: 7833462

Claim:
A method for manufacturing at least partly plastic vehicle parts in a mold with at least one mold cavity, comprising the steps of: at least partly closing the mold, wherein the at least one mold cavity is brought in a first position by moving at least one wall part of the at least one mold cavity; introducing plastic into the at least one mold cavity, the plastic being introduced in a molten condition; upon complete closure of the mold and/or movement of said at least one movable wall part, bringing the at least one mold cavity in a second position, the at least one mold cavity in said the having a smaller volume than in the first position; by bringing the at least one mold cavity from the first position to the second position, the plastic fills the respective mold cavity completely, the mold being provided with the at least one mold cavity with the at least one movable wall part, wherein operating means are provided for a controlled movement of said wall part between at least the first and the second position, wherein a displacement of said wall part is controlled such that during use adiabatic heat development occurs in plastic in the mold cavity through pressure change in and/or displacement of the plastic.
