Injection blow molding system with thermally insulated mold configurations

Injection blow molding tooling process comprising:

• (a) providing upper and lower body mold halves configured for attachment to upper and lower die sets, respectively;
• (b) connecting upper and lower neck mold halves with the upper and lower body mold halves, respectively;
• (c) connecting upper and lower thermal barrier plates with the upper and lower neck mold halves, respectively,
• wherein upon the connecting of step (c), upper and lower insulating gaps are presented between the upper and lower neck mold halves and the upper and lower thermal barrier plates, respectively;
• and
• (d) connecting upper and lower interlock halves with the upper and lower thermal barrier plates, respectively.

Tooling for forming a molded article from a parison with an injection blow molding system, said tooling comprising:

• upper and lower body mold halves,
• wherein said upper and lower body mold halves cooperatively present a body cavity configured to define an exterior shape of a body of the molded article;
• and
• upper and lower insert halves coupled with said upper and lower body mold halves respectively,
• wherein at least a portion of said upper and lower insert halves cooperatively present a neck cavity configured to define an exterior shape of a neck of the article,
• wherein said upper insert half includes an upper insulating gap separating first and second portions of said upper insert half,
• wherein said lower insert half includes a lower insulating gap separating first and second portions of said lower insert half.
