Diffusion Bonding Technology

Features

Diffusion Bonding

This technology heats and applies pressure on joint materials and uses molecular diffusion to bond them.

- As for plastics -

Since they hold no free electron, bonding is possible by combining them with third components due to the diffusion phenomenon of polymer.

Advantage of Diffusion Bonding Technology

- Multi-layer Manifold -

Diffusion bonding technology makes it possible to fabricate complex and smooth inner flow channels, which was not possible with traditional machining works.

Downsizing Units are made by combining pumps and valves.
3D Channel Structure Structuring 3D channels is possible by lamination of 3 or more layers.
No pipes Inner flow channels do not require pipes nor tubes.
No contamination There is no residue since adhesives (styrene monomer, etc.) are not used. Perfect for probe assy using just a small amount of reagents.
High adherence The interdiffusion effect realizes an even more excellent adherence.

Application of Diffusion Bonding Technology

Space conservation of analyzers may be one of the suitable applications as modularizing units by combining with pumps, valves, etc.,

Manifold

Diffusion bonding technology makes it possible to fabricate complex and smooth inner flow channels, which was not possible with traditional machining works.
