Achieving a reliable bond: Ultrasonic welding devices and graphite products for thermal management.
Ideal for batteries and high-speed motors! A permanent, strong, and metallurgically pure bond with excellent physical properties is achieved in an instant!
Shunk Carbon Technology Japan Co., Ltd. has established technical bases not only at its headquarters factory in Germany but also in the United States, Morocco, and China, providing comprehensive services worldwide. 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. Our company manufactures wear-resistant parts tailored to customer needs, including bearings used in cooling pumps and fuel pumps. 【Welding Technology】 ■ Spot Welding: Ultrasonic welding for a wide range of applications (typically sizes from a few mm² to 100 mm²) ■ Bending Sonotrode: Suitable for hard-to-reach welding spots ■ Rotary Seam Welding: Achieves continuous linear metal seam welding for applications such as solar thermal power, photovoltaic power, and composite pipe manufacturing. 【Features of Graphite Products】 ■ Highly reliable, high-performance, and efficient parts ■ Possible to incorporate from the development stage through simultaneous parallel design *For more details, please download the PDF or feel free to contact us.
