Abstract

Abstract

The production of preforms for PET beverage bottles has become increasingly demanding in recent years. On the one hand, there are increasing requirements due to the material mix and, on the other hand, a lack of expert knowledge. Netstal offers new solutions for these requirements. Thanks to these improved functions, expert knowledge is always available to all operators at the machine. This makes production more efficient and safer.

​

In order to minimize the ecological footprint, technical innovations have been introduced on the Netstal PET-Line to further reduce energy consumption. This makes production more energy-efficient and cost-effective.
