摘要：
A method and an apparatus are disclosed for processing plastics, in which the material in incoherent solid state is dehumidified in a hopper and is then melted in an extruder, after which the molten material is used in a moulding device for moulding by injection and/or by blow moulding and/or compression, and in which a set point pressure value of the molten material is set on the basis of a measured residual humidity value of the dehumidified incoherent solid material, so as to decrease the pressure value by a preset variation value if the measured residual humidity value is lower than a reference value and to increase the pressure value by a preset variation value if the measured residual humidity value is higher than said reference value.
