About us

HPAMT( (Nantong Hupan Advanced Manufacturing Technology Co.,Ltd) is an advanced technology company specializing in innovative dissimilar metal joining solutions. We excel in the manufacturing of Aluminum-Steel Transition Plates, Pipes, and Flanges using Friction Stir Welding (FSW), delivering high-performance and durable bonding for industrial applications in Shipbuilding, Energy, Semiconductors & Aerospace.

Distinguished from conventional welding techniques, our FSW-based manufacturing process achieves solid-state metallurgical bonding without melting the base materials, effectively eliminating common defects such as porosity, thermal distortion, and brittle intermetallic compounds. Each product undergoes a rigorous multi-stage quality control system, including dimensional precision inspection, mechanical performance testing, and corrosion resistance assessment, ensuring full compliance with the strictest industry standards such as AWS, DNV, and ASTM. Our in-house R&D team continuously optimizes welding parameters and product designs, enabling us to provide customized solutions that meet the unique technical requirements of complex engineering projects.

By combining the lightweight advantage of aluminum with the high strength and durability of steel, our transition components play a pivotal role in reducing equipment weight, improving energy efficiency, and extending service life across target industries. For shipbuilding, our products contribute to lighter hull structures and enhanced seawater corrosion resistance; for the energy sector, they support the reliable operation of renewable energy equipment and traditional power infrastructure; for semiconductors and aerospace, they deliver high-precision, high-performance components that meet the most demanding application scenarios. We are committed to establishing long-term strategic partnerships with global customers, providing one-stop solutions from product design and prototyping to mass production and after-sales technical support.
