Continuous welding of filtration material requires the highest level of precision. The Herrmann Ultrasonics (Booth 881) Microbond CSI system, consisting of the VE Actuator, Microgap controller and high-performance Ultrabond generator guarantees consistent weld quality. Integrated in all Microbond systems is the patented Microgap control process, which ensures constant production quality via closed loop processing by monitoring the gap between the sonotrode and the anvil drum.

The Microbond CSI technology energy is only directed to the weld bond points and does not further restrict the filter laminate, nor change the fiber content; with typical thermal bonding heat radiates outside the bond zone. 

• Small bond points safeguard against restricted airflow, a common problem when using adhesives. 
• Multi-laminate structures with/without mesh reinforcement can simultaneously be incorporated. 
• Pinholes are eliminated using the Microbond CSI technology.
• Loss of performance due to bonding errors is reduced to 0.5-4%.
