Apparatus for manufacturing products from a material which is at least thermoplastically deformable, e.g. plastic, comprises a mold with mold cavities provided with slide(s), movement mechanism for moving the slide, closing mechanism for opening and closing the mold such that the mold cavity is released or closed respectively, and feed mechanism for introducing, with the mold cavity closed, the material in plastic condition into the mold cavity. Apparatus for manufacturing products from a material which is at least thermoplastically deformable, e.g. plastic, comprises a mold (2) with at least one mold cavity (3) provided with slide(s); movement mechanism (9) for moving the slide (8); closing mechanism for opening and closing the mold such that the mold cavity is released or closed respectively; and feed mechanism for introducing, with the mold cavity closed, the material in at least plastic condition into the mold cavity. The movement mechanism for moving the slide are arranged for moving the slide forward in the mold cavity at a high speed relative to the movement speed of the mold parts upon their opening and closing, from a position at least partly retracted from the mold cavity, such that, as a result, the material is displaced in the mold cavity for obtaining the filling, preferably at a high speed such that adiabatic development occurs in the mold cavity. Independent claims are also included for: (a) a method for forming plastic products, in which in a mold cavity an amount of plastic is introduced in plastic condition, and upon which at least one slide is moved at least partly into the respective mold cavity while compressing and/or displacing at least a part of the plastic, while the speed of movement of the slide is high that adiabatic heat development occurs in the plastic, such that the plastic becomes more liquid, at least its viscosity is decreased; and (b) use of an injection mold with at least one slide, while, during an injection molding cycle, the slide is moved in a mold cavity of the mold at a speed such that adiabatic heat development occurs in a mass introduced into the respective mold cavity.
