Diffusion bonding is a process used for joining layers of sheet metal together by using the principle of solid-state diffusion. Sheets of metal are stacked together, they are heated to half the melting temperature of the base material, and pressure is applied to the stack. This causes some of the electrons from each sheet of metal to migrate to its neighboring sheet until the stack is internally welded together.
The Fotofab process of diffusion bonding precisely joins layers of sheet metal, that we have manufactured, together through heat and pressure, creating a single laminated sheet, with almost unlimited possibilities for internal part structures. Numerous small, precision parts can be created within each laminated sheet. We manufacture heat sinks, radiators, medical device capillaries, fuel cells, plenums, extrusion dies, and hundreds of others components.
Using our photo etching process, Fotofab manufactures each of the flat lamination layers which are bonded to form three-dimensional structures. An added bonus is that part complexity does not add to the cost!
