Large PET Preforms
Injection Molding of Large PET Preforms At Maximum Yield
The inclusion of a high-quality PET mixing screw as a feature of our EM320-PET Toggle Type Injection Molding machine has enabled a customer to achieve a consistent yield of over 99% since 2016 in the manufacture of large PTE preforms.
In fully automatic mode, driven by the SVP/3 Servo Drive and using the Beckhoff CBmold300 controller on an EtherCAT digital main bus, the system achieves a cycle time of 45s for 4 cavities, at a clamping force of 320 tons, with a shot weight of 250g each and thickness of 6.1mm in this demanding application.
