Application Example Dam and Fill

Protection of Highly Complex Areas

Dam and Fill applications protect highly complex areas particularly reliably. In the first step a dispensing robot applies a highly viscous barrier – the dam. In the next step the robot dispenser fills that area with a filling material. The dosed area is sealed with flowable material and therefore protected.


Robotic Dispensing with Dam and Fill

Fritsch GmbH from Kastl/Utzenhofen knows all about robotic dispensing systems. However, the filling of a circuit carrier with silicone proved to be a challenge. There was only one solution for a clean result:
The manufacturer of SMT technology used the tried and tested eco-PEN by preeflow. High repeatability, precise processing and user-friendly handling: characteristics that distinguish preeflow products. Fritsch was soon impressed.

And it has not disappointed. The preeflow eco-PEN provides reliable volume dispensing of a wide variety of materials. It is capable of compensating for external factors such as the ambient temperature.

An all-round talent for clean dispensing results.


preeflow Dam and Fill advantages:

  • Protection of highly complex components
  • Clean dispensing
  • Compensation of external factors
„High repeatability, precise processing, user-friendly handling and short set-up times are particularly important to us. These are the characteristics that distinguish the preeflow dispensers.“Andreas Hiller, Sales/Application
