High generator power, rigid sonotrode support and the precise control of high weld forces offer optimal solutions for cross seal and laminating applications.
The CSI variants of the MICROBOND product line are characterized by their modular extension options and enable operating widths of several meters. Thanks to the rigid CSI support and the trapezoid sonotrode geometry it is possible to install sonotrodes at minimum distance to one another. The result: a homogeneous end product without disturbing interruptions.
Herrmann Ultraschall focuses on maximum transparency in the weld process. Only in this way is it possible to understand, control, and monitor the ultrasonic joining process. Prevention of redundant rejects, reduction of standstill time, and high availability guarantee an economical manufacturing process. Thanks to the mobile MICROBOND tablet, the process can be monitored, assessed, and optimized directly at the weld station.
The continuous welding of web material requires the highest level of precision. Even slightest variations in the gap width between the sonotrode and the rotary anvil of a few µm have an influence on good or suspect welds. Mechanical influences such as axial and cross-directional weld forces or temperature-related material expansion must be understood and controlled in detail.
These factors are compensated by the patented CSI support, which ensures that the sonotrode is directly clamped at the vibration node (vibration-free point) by means of a decoupled mechanical system. This reliable support technology maintains consistent weld results, even in applications with large contact pressure areas or intermittent cross-directional weld surfaces.
