Abstract: The invention relates to an apparatus for fine and controlled adjustment of an injection molding process and a related industrial process.The apparatus (1) has a sealed mold (2) supplied with fluid reactive resin via a supply inlet (8) and by means of a mixing and injection head (9) so as to impregnate with said resin fibers of composite material loaded inside a cavity (6) of the mold (2) and wherein at least one storage container (10) having an inlet/outlet opening (11) in fluid communication with an outlet (13) of said injection head (9) is provided so as to store a predefined quantity of fluid resin inside a storage chamber (16) prior to completion of the injection phase. Advantageously, the storage container (10) is a cylinder (18) defining internally a storage chamber (16) which houses slidably inside it a plunger (21) operated by an actuator (25) configured as a cylinder/piston assembly arranged as a coaxial extension of said cylinder (18) and comprising an actuating piston (15) having a stem (22) coinciding with the stem of said plunger (21); the cylinder (18) of the storage chamber (16) and the cylinder (14) of said actuator (25) having cross-sections different from each other.
