XVENT is a patented innovation related to special vents design on blow moulds (body and base mold). The strategic positioning of the vents in the most critical areas helps to exhaust the air between bottle-wall and mould-inner-surface more easily and faster; this permits a better formation of complex shapes and allows a reduction of blow pressure during bottle production.
