Internal flow path diffusion bonding (ceramics, quartz glass, pure molybdenum)
Through diffusion bonding, complex shapes with internal flow paths can be realized! We are currently offering a collection of bonding case studies featuring materials such as quartz glass and pure molybdenum!

**Diffusion Bonding** A technology that joins materials at the atomic level at the bonding surface through heating and pressurization. It does not use intermediate materials such as filler metals. **Materials with Diffusion Bonding Achievements** - Alumina - Aluminum Nitride - Quartz Glass - Silicon - SiSiC Composite Material - Pure Molybdenum - Pure Nickel **Examples of Bonded Components** Material: Quartz Glass Size: φ390 x 11t Internal Flow Path: Width 5mm x Depth 3mm x Flow Path Length 3393mm Square Deep Hole: □1.1 x Depth 360mm (Longest Part)
