Claim:
A method for manufacturing plastic products having a bottom and a sidewall, the method comprising the steps of: closing a mold, while a second movable wall part is brought into a retracted position and a first movable wall part is in a forward position to define a mold cavity having a first volume; injecting plastic into the mold cavity defined by the mold, the mold cavity being formed at least between a core part and a wall surface of the second movable wall part that is situated at a first distance from the core part; moving the second movable wall part into the mold cavity while the mold is closed to a forwardly moved position with respect to the first movable wall part, such that the respective wall surface is brought to a second distance from the opposed core part, which second distance is smaller than the first distance wherein the mold cavity has a second volume smaller than the first volume, the second movable wall part displacing at least a portion of said plastic, such that the whole mold cavity is filled with plastic; allowing at least a part of the plastic to solidify; opening the mold and moving the first movable wall part, such that the product formed can be withdrawn from the mold.
