Abstract
An apparatus (1) for injection of plastic materials has: a tubular frame (8); an injection cylinder (9), fixed to the tubular frame (8); a shaft (10), which extends along a longitudinal axis (A) and has a first portion (26), shaped like a screw conveyor and set within the injection cylinder (9) for feeding and fluidifying the plastic material, and a second portion (28); and an actuation assembly (11), which can be selectively coupled to the second portion (28) of the shaft (10) for selectively rotating the shaft (10) about the longitudinal axis (A) in the step of f luidif ication and advance of the plastic material and for pushing the shaft (10) along the longitudinal axis (A) in the step of injection of the plastic material.
