HiQ - The New Machine Generation

Herrmann Ultrasonics has been setting technical benchmarks in the ultrasonic welding of thermoplastics for 50 years . At MD&W West 2011, the company will be presenting a completely new generation of machines - flexible and energy-efficient. Because every welding application is different, the HiQ line adapts to all requirements with modular flexibility.

Ultrasonic welding of plastics is an intricate task. Each application is different and places different requirements on the complex interplay of factors. Acoustic waves - or ultrasound - are converted into mechanical vibrations to generate molecular heat. The weld process is controlled by sophisticated control software and must be adapted to the geometry and condition of the welded parts, which are made from amorphous or semi-crystalline polymers. Each welding tool, the sonotrode, is unique, as it is adapted to the application at hand.

New HiQ line: The right welding machine for every application

The new HiQ generation of machines from Herrmann Ultrasonics addapts perfectly to this complexity. The product line addresses various customer requirements like never before, and clients will find the right machine to suit their application, market and budget. Thanks to intelligent output and equipment classifications the HiQ offers a wealth of options and variants in both the machine environment and the software. Users can now configure welding applications in a more targeted and individual manner. Every one of the new HiQ machines satisfies Herrmann's defined standard of reproducible high-quality welding with a stable and robust machine. Visualization of the welding process is accomplished in a user-friendly touch screen display. The machines are equipped with proportional valve technology and a position measuring system as standards. The safety concept meets all relevant worldwide standards. Intuitive software menus electronically control all aspects of the weld process.. The software is also Unicode-compatible for easy language adaptation.

Energy efficiency

Ultrasonic welding uses 75% less energy than other thermal joining processes. This is due to the fact that the welding tools remain cold and have a low energy requirement. The ultrasonic vibrations are specifically applied to the joint area for only a matter of milliseconds during welding. Our new, redesigned ultrasonic generator works with an extremely high degree of efficiency (over 80 %) when powered. The new HMC (High Motion Control) drive concept -(offered in the upper machine segment) helps the user realize faster production. The closed-loop control module combines the benefits of pneumatic technology with the speed of an electric drive. The customizable stroke allows the part to be approached more quickly, while the SoftTouch mode ensures gentle contact to avoid damage to the joint area - thus achieving a measurable reduction in non-productive time. There is also a new energy saving mode that switches the machine to standby, and disengaging from the air supply after a time specified by the operator.Complete new machine line debuts at MD&M, West 2011

HiQ DIALOG: force profiling with four weld forces, extended memory and weld process graphics. The 1000 weld memories each store 300 welds, including all the relevant graphics - making full use of historical monitoring. The new force profiling feature makes it possible to achieve the strongest joints for the most demanding applications. In the user interface, the EasySelect mode eliminates all but the most important primary functions for better usability. The user can revert to expert mode, with all functions activated, at the touch of a button. With the new QCS (Quick Change System, no tools needed), the ultrasonic stack can be mounted without the need for hand tools.

HiQ VARIO: Proven proportional valve technology and digital high-performance generators. A range of pneumatic drive units with various stroke and cylinder diameters are available, all of which feature Herrmann's proven proportional valve technology. Graphic visualization of the joining process aid the operator when programming process parameters and recording quality during production. When selecting a generator, users can choose between 3 frequencies and several power outputs up to 6000 W. Standard equipment includes multiple USB high speed interfaces, printer and Ethernet connections.

HiQ LOGIC: Five welding modes for reproducible high-quality results. Even in the entry-level class, a travel measuring system and proportional valve technology form part of the basic equipment. A password protection feature and volume counter also come as standard, as do the five operating modes: time, power, energy, depth RPN and absolute distance. A clear 5.7" touch screen allows the operator to parameterize and check the weld process with ease. The universal structure of the operator interface makes it extremely easy to switch to all other Herrmann Ultrasonics welding machines.

Herrmann Ultrasonics is a global leader in ultrasonic plastic welding with offices around the world. The second generation of the family strives to uphold the tradition of turning customer requirements into cost-effective solutions. www.herrmannUltrasonics.com
