Diffusion Bonding Technology
From dissimilar metals to precision parts. Next-generation bonding technology without melting
“Adopted in aerospace, automotive, semiconductor, medical, and energy industries”
“Mass production available” “One-stop processing for speed”
What is Diffusion Bonding?
‘Diffusion bonding’ is a method of bonding by pressing base materials together at a temperature below their melting point with minimal plastic deformation, utilizing the diffusion of atoms at the joint interface.
By laminating, complex 3D shapes can be created, and by bonding dissimilar materials, new composites and novel materials with properties such as electrical conductivity, thermal conductivity, magnetism, and specific gravity can be developed.
Features & Advantages of Diffusion Bonding
- Bonding of dissimilar materials (metals) possible
→ Supports combinations that were difficult with conventional methods - High hermeticity and strength
→ Atomic-level bonding ensures extremely low leakage and long-term reliability - Maintains machining accuracy
→ No melting means minimal distortion and deformation, with excellent dimensional accuracy - Supports complex shapes, multilayers, and hollow parts
→ Lamination bonding enables integration of flow path components and microstructures - Large-area bonding possible
→ Uniform pressure and heating applicable to large heat exchangers and plate laminates - No melting or brazing required, clean process
→ No foreign substances or brazing material remain at the joint, suitable for semiconductor and medical fields

TIME is fast because of one-stop processing
From material procurement to machining, bonding, and finishing, everything is handled in-house with a one-stop process.
By eliminating external transport and outsourcing of each process, we achieve shorter lead times, cost reduction, and high quality simultaneously.
- Integrated support from machining to finishing
- Zero wasteful transportation costs
- Speedy delivery of high-precision, high-reliability products
