シュンク・カーボン・テクノロジー・ジャパン List of Products and Services

We would like to introduce our technology related to "ultrasonic metal welding." Ultrasonic welding is a forward-looking method that uses ultrasonic waves for metal bonding. In addition to bonding copper and aluminum materials, it is also possible to bond metal to glass. Our products are a total system solution from a single source. In addition to standalone standard equipment, we design our products around a modular system concept, achieving integration into fully automated production systems for ultrasonic welding equipment. Please feel free to contact us if you have any inquiries. 【Advantages】 ■ No thermal load on components ■ Higher quality with excellent cost performance ■ No need for additional materials such as filler ■ Digital monitoring of the welding process is possible ■ We provide a complete system solution *For more details, please refer to the PDF materials or feel free to contact us.

In addition to our headquarters factory in Germany, we have established technical bases in the United States, Morocco, China, and other locations, providing comprehensive services worldwide. 【Our Technology】 The ultrasonic welding technology that utilizes ultrasound for metal bonding is a forward-looking method. In addition to bonding copper and aluminum materials, it is also possible to bond metal and glass. By stacking the workpieces to be joined and applying mechanical vibrations at high frequency with low pressure, a permanent, strong, and metallurgically pure bond with excellent physical properties is achieved in an instant. 【Welding Technology】 ● Spot Welding: The most versatile application of ultrasonic welding, typically ranging from a few square millimeters to 100 square millimeters in size. ● Bending Sonotrode: Suitable for hard-to-reach welding spots. ● Rotary Seam Welding: Enables continuous linear metal seam welding, applicable in solar thermal power, photovoltaic power generation, and composite material pipe manufacturing. 【Advantages】 ● No thermal stress on components. ● Higher quality and superior cost performance compared to other welding and joining methods. ● No additional materials such as filler are required. ● Digital monitoring of the welding process is possible. ● We provide a complete system solution.
