Third largest economy in Europe with great ultrasonic potential
With the opening of the new location in Etaux, Auvergne-Rhones-Alpes region, Herrmann Ultraschall GmbH & Co. KG strengthens its presence in the French growth market. It provides the ideal basis for consulting, support and assistance without long travel distances or language barriers.
A global company with strong roots in the region: this is what Herrmann has developed into over the past six decades. To celebrate its 60th anniversary, the family company is donating to six organizations that help people locally.
A prestigious title: the auditing and consulting company Ernst & Young (EY) awarded Thomas Herrmann, Chairman of the Management Board of Herrmann Ultraschall GmbH & Co. KG, the prize as “Entrepreneur Of The Year 2021”. With the award in the category "Innovation", the jury acknowledged his creativity and commitment as entrepreneur.
The insertion of elastic threads can be complex and costly in the manufacture of hygiene products. Herrmann Ultraschalltechnik GmbH & Co.KG, Karlsbad, Germany, has developed a novel patented method for fixing elastic threads that simplifies handling, reduces the risk of breakage, enlarges the process window and lowers production costs.
Booming electromobility and the growing demand for fast charging technologies result in increasing system voltages for electric vehicles. This requires powerful cable harnesses and power rails, which in turn requires larger cable cross sections and/or metal sheet thicknesses. The higher the cross section, the more difficult the welding. For this purpose, Herrmann developed the Ultrasonic Power Stack 12000+ as an extension for their HiS VARIO W ultrasonic welding machines.
This year has been challenging, but we are very grateful that we could contribute to the fight against COVID-19 with our ultrasonic technology for face masks and breathing ventilators. And it is in this sense of gratitude and hope that we once again decided to support worthy causes this Christmas
Together with the packaging service provider Verdesoft, Herrmann Ultraschall has developed a cup and a tube that can be closed by ultrasonics. The packaging concepts have a comparable product protection as conventional plastic packaging and save up to 75% plastic.
This is the famous Building M where CEO Thomas Herrmann studied mechanical engineering at the Karlsruhe University of Applied Sciences from 1984 to 1989. Now the university has appointed him to the university council as alumnus and head of a family-owned yet globally operating technolgy company.
Thomas Herrmann is a manager, a maker and shaker and a philanthropist. He is a man who has also appeared on stage as an actor in front of thousands of visitors to the cult musical "Weihnachten neu erleben" (bringing back the Christmas spirit), to inspire enthusiasm for the charitable cause.
Process control in ultrasonic welding for medical sector
In the fight against the corona virus, ventilators and corona tests have come to the fore. Herrmann Ultraschall supplies well-known manufacturers with the welding technology to assemble the necessary components such as mouth and nose contact pieces, floats, filters and housings. The two software tools FSC and SonicCalibrate developed by Herrmann play an important role for quality assurance in the ultrasonic welding process.
At this year's Spring Challenge of the Karlsbad Municipality in southern Germany, we took third place in the category Bike Commuters Baden Württemberg with a team of 10 colleagues and 224 km per team member. In total, our team covered 2,462 km and saved 362 kg of CO2.
The Lower Saxony-based automotive supplier Zender Group, Osnabrück, specializes in carbon and textile products. The company recognized the need for personal protective equipment at an early stage and started to set up a mask production facility in record time.
Herrmann Ultraschall provides Arburg with a HiQ VARIO ultrasonic welding system free of charge for the Lossburg-based company's large mask project (see press release).
The use of softness-enhancing Air-Through Bonded materials (ATB) is increasing – typical hygiene applications are acquisition distribution layers (ADL), waist panels, and top sheets. Ultrasonic welding can offer process related and environmental advantages over glue and heat bonding. The nonwovens laboratory at Herrmann Ultraschall provides high-tech support for application solutions when it comes to bonding ATB.
Mono-materials and paper composites for packaging are increasingly in demand and the number of inquiries regarding new recyclable materials is increasing at the ultrasonic laboratory of Herrmann Ultraschall. Many of the major food companies have set themselves high sustainability targets and are testing the new materials.
Herrmann Ultraschall supplies the ultrasonic welding technology for the production of different face masks. Inquiries accumulate. Focus on short transport distances.
This year's Christmas donation in the context of our charity initiative “Herrmann Cares” is intended for education and goes to two schools in Karlsbad, Germany, to make subject-related project days affordable for all students.
Herrmann Ultraschall has been a specialist in ultrasonic welding for decades and is presenting its new HiS VARIO welding system for metal welding such as copper and aluminum at Productronica. The system can be used as a manual workstation or automatically integrated into production lines.
As of now there are few inquiries for the welding of recycled materials, ie plastics that already have been processed once or more before. The weldability must be determined empirically in the test laboratory.
Ultrasonic technology can also deliver good sealing results with narrow process limits, especially with regard to tightness and visual appearance. The thermal expansion is kept to a minimum. Thermal processes demonstrate disadvantages of excessive heat input, especially in the continuous welding of film webs.
Ultrasonics for cuff elastic is a relatively new topic. How were they processed before?
What is the most important aspect of thread processing?
What role does the rotary anvil play?
Where is this trend leading?
By means of the ultrasonic process, multilayer absorbent bodies, e.g. a diaper, including the SAP granules (Super Absorbent Polymer) can be welded glue-free and in one single step. Now Herrmann Ultraschall offers an innovative process for elastic cuffs.
Battery management systems (BMS) for cylindrical cells require precisely adjustable low weld forces. Herrmann has developed a new module which suits especially the welding of BMS to small cylindrical cells and finest materials, that can easily be integrated in existing production processes.
Design awards for the welding workplace of the future
The optimal human-machine interaction in regards to the functionality of the machine convinced both juries. Herrmann Ultraschall has received the IF Design Award 2021 and the Good Design Award 2020 for the new HiQ DIALOG ultrasonic welding machine generation.
