A process for production of thin-walled plastics mouldings is described, via injection of plastics melt into a mould which has at least one fixed and at least one movable mould half, where an aperture gap is formed between the two mould halves in the opened condition of the mould, and where the two mould halves form at least one cavity of variable size in the closed condition of the mould, and where the movable mould half is moved without interruption onto the fixed mould half and the mould is closed, and where the aperture gap between the mould halves is continuously reduced, and where the plastics melt is injected into the mould during the movement of the movable mould half onto the fixed mould half. A feature of the invention is that the injection of the plastics melt takes place in accordance with a prescribable screw advance velocity profile or in accordance with a prescribable pressure profile for the pressure in the space in front of the screw. |
