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 PET preforms.
In fully automatic mode, driven by 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.

*This machine series has been replaced and upgraded by our newer series of injection moulding machines.
