Abstract

The invention relates to an apparatus for fine and controlled adjustment of an injection molding process and a related industrial process. The apparatus () has a sealed mold () supplied with fluid reactive resin via a supply inlet () and by means of a mixing and injection head () so as to impregnate with said resin fibers of composite material loaded inside a cavity () of the mold () and wherein at least one storage container () having an inlet/outlet opening () in fluid communication with an outlet () of said injection head () is provided so as to store a predefined quantity of fluid resin inside a storage chamber () prior to completion of the injection phase. Advantageously, the storage container () is a cylinder () defining internally a storage chamber () which houses slidably inside it a plunger () operated by an actuator () configured as a cylinder/piston assembly arranged as a coaxial extension of said cylinder () and comprising an actuating piston () having a stem () coinciding with the stem of said plunger (); the cylinder () of the storage chamber () and the cylinder () of said actuator () having cross-sections different from each other.
