A method for manufacturing products using a mold having at least one mold cavity which is at least partly defined by at least two movable wall parts, wherein the mold is closed and the at least two movable wall parts (35A, 35B) are brought to a retracted position relative to the mold cavity, so that the volume of the mold cavity is enlarged relative to the volume required for a product to be formed, wherein at least partly molten material is introduced into the mold cavity and then in a first step a first one (35A) of the at least two movable wall parts is set into motion in the direction of a forwardly moved position and in a second step a second one (35B) of the at least two movable wall parts is set into motion in the direction of a forwardly moved position, wherein the movable wall parts are moved into said forwardly moved position for the formation of the product.
A mold for forming products, provided with at least one mold cavity, which mold cavity is at least partly defined by at least one first and at least one second movable wall part and first and second drive means for respectively driving the first and second movable wall parts between a retracted position and a forwardly moved position, wherein a control unit is provided with which the drive means can be controlled, such that in a first step the or each first movable wall part is set into motion in the direction of a forwardly moved position and in a second step the or each second movable wall part is set into motion in the direction of a forwardly moved position, and wherein the first and second movable wall parts are movable independently of each other at different stages in the molding process.
