PreWatcher Inline

Preform feeding, orientation and inspection: The PreWatcher Inline offers a compact 3-in-1 solution integrated directly behind the injection molding machine.

The inline solution for the quality control of your preforms

Directly integrated behind the injection molding machine, the PreWatcher Inline guarantees that your preforms are carefully fed, oriented and inspected. The 3-in-1 solution is particularly space-saving and only needs a floor space of 8 m².

By means of eight cameras, a non-contact and non-destructive all-round inspection of every preform is conducted. The transport system, developed and patented specially for the PreWatcher Inline, allows a comprehensive inspection without any blind areas.
