Liquid Dispensing Systems: Compatible for Every Application

When it comes to dispensing liquids the applications are as diverse as the technology. From Bonding and Glob Top to Encapsulating.
We have the right fluid dispensing system for every application.


Bonding is also referred to as structural bonding with a fluid dispenser. Adhesive dispensing is mostly used in industrial design and semi and fully automated manufacturing.

Dam & Fill

Dam and Fill applications protect highly complex components. First, a highly viscous barrier is applied. This area is then filled by a liquid dispenser pump with a filling material.

Glob Top

Glob Top dispensing technology protects highly sensitive components and elements from vibration or external environmental influences. For this purpose, a liquid matrix is applied, which then hardens.
