System for oval plastic containers
The newly developed ProShape process from Krones functions by utilising the field-proven heat-up and stretch blow-moulding technology of the company’s current Contiform series, and combining it with a new module for orientation and selective temperature control of the preforms concerned. The requisite temperature profile is applied to the preforms using temperature-controlled aluminium moulds specifically designed to meet the requirements of the subsequent bottle, thus achieving purposefully optimised material distribution for the downstream stretch blow-moulding process. This enables very accurate profiles with sharply defined temperature boundaries to be achieved, permitting stable thick-walled areas to be provided directly adjacent to thin-walled segments. The system can also quite simply be switched off when round bottles are to be produced in a standard process.
