    [EXHIBITION] SEMICON CHINA 2025

    Date: March 26th ~ Mar 28th, 2025

    Venue: SNIEC, Shanghai, China

    Booth No: 4681

    KSM participated in SEMICON CHINA 2025, held from March 26 to 28, 2025, at the Shanghai New International Expo Centre (SNIEC) in Shanghai, China.

    The exhibition was organized under the theme “Cross Global, Core Connection (跨界全球·心芯相联)”, emphasizing global collaboration and the integration of core technologies within the semiconductor industry.

    During the event, KSM showcased its welded Metal Bellows, along with other essential semiconductor process components. The company attracted significant attention from clients particularly in the robotics and display industries, engaging in numerous technical consultations.

    China’s robotics sector is experiencing rapid growth driven by national policies such as “Made in China 2025” and the Robotics Industry Development Plan. In particular, humanoid robots are expected to enter commercialization in 2025, further accelerating demand for high-precision components.

    Meanwhile, the display industry is also expanding through large-scale OLED-focused investments, solidifying China’s position as a key global production hub.

    Amidst these trends, demand for high-precision, flexible Metal Bellows is expected to increase, especially in applications that require durability and reliability.

    KSM aims to strengthen its market presence across China and Asia by providing premium-quality components and fostering tailored technical partnerships with global customers.
