Preform moulds

PETform, South Hall 15087, India, a manufacturer of two stage & single stage moulds for PET packaging, will show a 72-cavity preform mould for a Netstal PETline machine. It will also display a preform moulding solution for heavy thick walled preforms with an innovative post-cooling system that functions without the use of a robot.

The technology is based on empying an additional set of cores and two sets of aluminium sleeves to provide post mould cooling for approximately one additional machine cycle of cooling on the core and two additional machine cycles of cooling in the sleeves. It allows for earlier de-moulding compared to conventional outside mould cooling systems. These are currently being used in the industry but do not have the ability to control preform ovality if the preform is de-moulded too soon, says the company.
