The PreMon is the budget-friendly solution for a high-volume inspection of significant preform quality characteristics. The system gives you immediate production feedback directly after injection.

Powerful. Compact.
Preform Monitoring.

While the preforms being conveyed to the packaging unit, the PreMon delivers real-time quality results of your transparent, translucent and opaque preforms. Due to its minimal footprint, the system can easily be integrated between the injection molding machine and the packaging unit. Active conveying at production speed ensures a smooth production process. With the option PreMon PLUS, you can even add an active bad part ejector.

The system combines a revolutionary massive parallel orientation technology with a preform monitoring concept. It provides a quality overview of your preforms at all times. Immediate production feedback in the form of statistical analyses and alarms help you to further expand your production know-how and get a full production overview. Additionally, the forecast of production trends help you to take corrective actions before problems occur.

Key Components of the PreMon


Preform monitoring

The monitoring unit of the PreMon stands out by its space-saving design. With a minimal footprint, it perfectly fit between the injection molding machine and packaging unit.


Bad part ejector

Combined with the monitoring unit, the active bad part ejector enables you to improve the overall quality of your individual octabins. This leads to a reduction of the defect rate during the initial filling of your octabins.


Command station

The command station consists of the electrical cabinet as well as a monitor. The monitor displays the IntraVision software with all relevant information about the performance of your production.

Easy and fast reference creation

The PreMon Wizard allows the creation of a new reference during running operation within one minute. The operator is guided through the setup process by simple steps, which are even performed automatically by the system in many cases. A new reference can be created while the production process continues and your products are being inspected.
