At a glance, diffusion bonding means for you:
The types of furnaces
The hot presses are generally designed for temperatures up to 1350 °C and achieve pressing forces of up to 800 tons. For larger press platens, the forces are transmitted by means of multi-pillar technology to ensure optimum and homogeneous force distribution. Oil diffusion pumps or turbomolecular pumps are used to generate the high vacuum. The systems can be equipped with two different types of heating elements: For carbon-sensitive and carboninsensitive materials.
Furnace for carbon sensitive materials
The "MOV-HP" is our diffusion bonding system with all-metal heating insert. The series can be used for all diffusion bonding materials, including those materials that have a particular sensitivity to carbon, such as titanium alloys, special nickel-based alloys or low-C stainless steels. Similarly, this type of furnace is excellent for diffusion bonding of aluminum components where no surface pretreatment is required. Typical examples are plates with cooling channel structures, ("Cooling Plates").
Furnace for materials without increased carbon sensitivity
The "COV-HP" is the diffusion bonding furnace with heating insert made of graphite materials. The series can be used for all diffusion-bonding materials that have no particular sensitivity to carbon. At the same time, the systems are characterized by particular robustness, durability and economy.
Application areas and markets
Diffusion bonding technology has a wide range of applications in a wide variety of markets. Because it allows the joining of small components through to large components, many industries benefit from this process. These include:
Typical workpieces for these industries include planar heat exchangers, cooling plates, turbine parts, shower heads, high-performance heat exchangers, and other components. Since internal complex geometries are possible, diffusion bonding is also suitable for mold and tool making with near-contour cooling channels.
