Additional injection modular system applicable in any process for molding parts or products by polymer injection is provided, wherein injecting one or more parts or products with a single material or a plurality of polymer materials requiring separate, simultaneous or sequential complementary injections becomes necessary in addition to the injection of a base material processed in a conventional injection machine. The system has a module configurable in both composition and dimension with optimized rheological and energy behavior which is installed between the closure assembly plates of the base machine and the mold, comprising a frame, front mold clamping plate, structure clamping plate, structure spacer blocks, at least one additional injection assembly, at least one additional injection nozzle and injection nozzle extension. The system herein can be used in the production of parts by injection processes generally designated as multi-component injection.

An injection molding apparatus (100) comprising a rotor (240, 252, 2202), interconnected to a distal end (DE) of one or more elongated cables (237, 237, 248, 249, 2206) in an arrangement such that the one or more elongated cables are controllably rotatably drivable (R, R2, R3) via controlled driven rotation (R) of the rotor around the rotor axis, wherein the one or more elongated cables (237, 237, 248, 249) have a cable axis (CA) and are flexibly bendable along at least a portion of their axis (CA) into a curved or curvilinear configuration (CF), a rotary to linear motion converter (228, 230, 300, 700, 800, 1200, 1201, 2208) interconnected to the rotor and an upstream end of the valve pin (216, 218, 301, 501, 708, 808, 1222).
