Right: Netstal made preforms at Drinktec on a new PET-Line 4000 injection moulding machine


The automation for the exhibit is provided


by Zubler and the tool comes from Otto Hofstetter.


Efficient preforms Netstal presented a new-generation PET- Line 4000 injection moulding machine at Drinktec earlier this year. During the show, it produced 6.9g PET


preforms with a 25/22 thread, using resin with 30% recyclate. To boost sustainability, the pre- forms produced were then fed back into the PET recycling loop. Part of the solution was a new mould from Krones


Group sister company MHT – with 144 cavities and an integrated self-cleaning function. The PET-Line 4000 operates the mould with a fast cycle time of 4.8 seconds, producing around 108,000 preforms per hour with a clamping force of 400 tons. For higher output at the same clamping force, MHT offers a mould with 160 cavities. For maximum output, customers opt for the PET-Line 5000, which can be equipped with up to 192 cavities. A key element in increasing efficiency in preform


production is continuous optimisation of energy efficiency, which is achieved with the integrated recuperation of kinetic braking energy from the clamping unit and post-mould cooling station. The optional System Pressure Reduction helps raise efficiency further. When this function is activated, the pressure in the hydraulic system is maintained at the optimum point, which is often below the maximum pressure. In cooperation with IMDvista, Netstal has integrated a quality monitoring system into the


PET-Line. The camera-based inspection system allows real-time detection of defects. It can also be used flexibly for new preform designs. With integrated quality control, users can identify potential weak points in the injection moulding process at an early stage.
