HERRMANN ULTRASCHALLTECHNIK GMBH & CO. KG

The core of this ultrasonic welding machine is the patented pneumatic HMC drive concept. It combines the benefits of pneumatics with the dynamics of an electrical drive and allows for selection of any optional start point for the weld process. The SoftTouch mode protects the sensitive joining area of the plastic parts to be welded during contact of the sonotrode.

The name delivers what it promises. The ultrasonic welding machine HiQ VARIO can be configured to completely suit the customer’s needs. A large number of pneumatic drive modules with different strokes and cylinder diameters are available, always including the reliable proportional valve technology by Herrmann Ultraschall.

Robustness, accuracy, and simplicity are attributes characterizing this ultrasonic welding machine. The entry-level models already include a position measuring system and proportional valve technology as basic equipment. Moreover, password protection and part counter are standard. Precision guiding rails and reliable drive components ensure repeatable welds.

Simplicity without having to abandon the proved Herrmann Ultraschall standards – that are the characteristics of this machine type. Proportional valve technology and digital high-performance generators are basic equipment. A solid machine design with precision guiding rails and proved drive components are the foundation for quality and repeatable welds.

The most simple way of welding thermoplastic materials is to use the ultrasonic manual welding device. This is particularly well suited for applications in prototype design, for processing of single products, small series and repairs. Regardless of caulking, swaging, staking, cutting, or spot welding, the HSG ultrasonic manual welding device is easy to use, provides variable power rating, and can be equipped with all types of conventional sonotrodes (35 kHz).

With the help of the MULTICELL concept, small multi-head applications can be easily implemented. In general, the plastic parts to be welded are loaded directly below the sonotrodes. A shuttle table can be optionally integrated for improved handling. This modular concept is particularly suitable for 20 kHz applications with sound insulation and can be customized by installation of a large number of accessory options. The compact make-up and high degree of mobility allow for universal application in manufacturing.

The solid machine design of the h-frame press with section steel frame structure is the basis for integration of multi-head tools. Equipment with up to 16 ultrasonic generators allows for cycle time-optimized process sequences in one processing station. The weld tools are moved far up by means of a pneumatically operated H-frame so that large-volume plastic components can be comfortably loaded into the work station. Additional solutions available for quick and safe tool change.

Shuttle table machines are characterized by an operating area that is separated from the loading station. The plastic parts to be welded can thus be optimally loaded into the equipment. Thanks to good accessibility, assembly and loading tasks can be easily performed. Can optionally be designed with one or more work stations. Approach of several operating positions is performed by means of a freely programmable linear drive. In this way, weld tasks can be divided into individual process steps. Tool change systems: optionally available.

Rotary table machines are used for applications that involve production of large counts in cycle time-optimized manner. The machine design allows for dividing the application into several process steps. The number of operating stations depends on the respective task. The individual operating steps are performed in the different stations within the work space simultaneously with loading in the loading area. Indexed tool change is optionally possible.

Optimal machine design for 20 kHz applications for which the joining process must be precisely performed by several sonotrodes in a single weld process. The rigid sonotrode support is realized by means of individual alignment modules and allows for accurate positioning even at large weld forces. Contrary to conventional designs, the weld stroke is performed by the anvil. During this stage, the plastic parts to be welded are moved against the stationary sonotrodes. Thus, it is possible to obtain machine cycle times of less than 10 seconds.
