More PET Preform Cavities For Smaller Presses

Tighter cavity spacing allows PET preform molds with 50% more cavitation to be used on smaller presses.

Tighter cavity spacing allows PET preform molds with 50% more cavitation to be used on smaller presses. This new development comes from Mold & Hotrunner Technology (MHT) of Germany in cooperation with Mold Hotrunner Solutions (MHS) Inc., Georgetown, Ont. PET preform molds with up to 96 cavities can be used on a 330-ton press, while up to 192 cavities can fit on a 660-ton press. Molds with up to 48 cavities can run on a 192-ton press. MHT says high preform quality is ensured by a low-mass hot-runner manifold whose reduced mounting height minimizes platen deflection. MHT says other innovations include the new Switchbar interchangeable cooling-water management system and an improved slide frame that facilitates mold maintenance.
