The Prefero PET injection moulding machine
Prefero is the core of the Krones preform system. The injection moulding machine is designed as a hybrid machine with electrical mould movement. Prefero is not only impressive with a best-in-class lock-to-lock time of a quick 1.9 seconds (400 t). Thanks to an integrated energy recovery system, up to 20 percent of the total energy consumption can be saved as compared to competitors' machines.
- Lock-to-lock time of a quick 1.9 seconds (400 t)
 - Lateral removal unit with post-cooling system
 - Preform interior cooling system
 - Energy recovery from mould and robot movement reduces the total energy consumption by up to 20 percent*.
 - Processing of 100 % rPET is possible.
