Hupan’s leading innovation lies in advanced friction stir welding (FSW) technology. They specialize in producing bimetallic components—including aluminium-steel transition boards, tubes, flanges, and copper heat sinks—engineered for use in high-demand sectors like maritime engineering, petrochemicals, low-temperature piping, metallurgy, and AI data center cooling systems .
Their unique FSW process enables robust and consistent welds of dissimilar metals, a major challenge in hybrid-material manufacturing. Their expertise has led to two granted patents for specialized FSW joints tailored to shipbuilding and cryogenic vessels .
