Abstract

Method and device for determining the switching increase from the injection pressure to the subsequent pressure in the injection molding machines depending on the clamping pressure of the injection molding mold, characterized in that the time interval for the generation of the pressure of injection is shortened in such a way that in the pressure curve for the injection pressure and the subsequent pressure interferes a pressure impulse, being maintained the total pressure that is composed of the edition of all pressures -always more reduced- than the clamping pressure that has previously been determined for the cast iron mold.
