Technology & Products
Key Products
Vacuum Diffusion Welding Equipment; Diffusion Welding Process Development; Precision Component Manufacturing (e.g., heat exchangers, cold plates); Material Connection Services
Technological Advantage
Proprietary solid-state diffusion welding process achieves hermetic, void-free bonds in dissimilar metals and large planar structures, protected by patents (e.g., CN118102689A) and recognized as a national 'Little Giant' enterprise. Technology avoids melt-related defects, enabling high-integrity components for nuclear and aerospace where conventional AM fails.
Differentiation
Value Proposition
Enables production of large, monolithic, leak-proof components (e.g., 2-meter PCHE cores) via solid-state diffusion welding, eliminating melting defects like porosity and residual stress, reducing lead times from months to weeks compared to traditional brazing/welding.
How They Differentiate
Focuses exclusively on solid-state diffusion welding (SHL) for large-format, high-integrity metal components, unlike mainstream metal AM competitors (EOS, Velo3D) using melt-based PBF or DED processes. Offers integrated equipment+process+part manufacturing solution.
Market & Competition
Target Customers
Aerospace, defense, nuclear energy, hydrogen energy, and ocean engineering OEMs requiring hermetic seals, dissimilar material joining, and complex heat exchangers.
Industry Verticals
Aerospace; Defense; Nuclear Energy; Hydrogen Energy; Ocean Engineering; Rail Transit
Growth & Milestones
Major Milestones
Founded in 2016; Developed China's first 1200mm-capable ultra-large diffusion welding equipment in 2017; Named to 2025 National Specialized and New 'Little Giant' list; Closed Series A+ round in 2025
