International Patent regarding integrated injection-stretch-blow mould for the manufacture of bi-orientable thermoplastic recipients
This technology efficiently converts your existing
injection Moulding Machines into an injection stretch blow moulding machine. This invention refers to an integrated mould for
the manufacturing of PET, PVC, PP and other bi-orientable
thermoplastic recipients by injection-stretch-blow
moulding process. In the first stage pre-forms are
produced. In a second and third stage, the pre-forms
Due to the fact this integrated mould combines all needed stages of injection-stretch-blow production, it allows that with minimum equipment, associated to an injection unit or mould sustentation platform, the production of bi-orientable thermoplastics is possible without investment in specific, expensive machines. The integrated mould occupies the physical space normally destined to injection moulds. The potentialities of the machine and physical space needed in the plant are maximised and there is no need to transport the pre-forms to a second stretch-blow-machine.
