Apparatus for injection molding of containers, or preforms for containers, in plastics material

摘要

The equipment (1) is for the moulding of plastics containers made of two different materials (A, B), particularly for the production of parisons (F) for PET bottles comprising an inner portion (F1) of virgin PET (A) and an outer portion (F2) of recycled PET (B). The equipment (1) comprises a die plate (PS) having rotatable supports (SG) each carrying a pair of cores or male elements (M) which are thus associated alternately with matrices (S1, S2) of two different types so as to produce the inner portions (F1) and the outer portions (F2) of the parisons (F) in two successive moulding steps.
