Diffusion Bonding Services

In 2022, PVA TePla America (PTA), in Corona California, became fully operational as a contract service house for diffusion bonding joining. Client interest has grown steadily.

To spread adoption, the Diffusion Bonding Group at PTA welcomes inquires seeking R&D or commercial contracting.

The usefulness of diffusion bonding is maximum with a combination of discreet materials selection, tight geometrical tolerances, and high-purity service assembly performance. Its successful implementation is a collaboration of meticulous mechanical design, and highly controlled materials processing.

Parties developing avant-garde technologies related to the follow areas may best be suited to benefit:

• Semiconductor Processing Equipment Assemblies
• Heat Exchanger Assemblies (HXA)
• Electrification
• Battery Packs
• Microfluidic Assemblies
• Aerospace & Space
• Advanced Communications Solutions
• Robotics
• Filtration Applications

The typical first step may be to initiate a limited-in-scope development program.

During the course of such action, the client is generally able to assess if the processing needs and manufacturer volume warrant the process to be aggregated internally to the corporation.  This would require a capital outlay for a furnace.  Currently, there is a long lead-time for delivery globally.   

If you have a new advanced design, or are struggling with manufacturing nuances, diffusion bonding may be the ONLY joining method that leverages the brightest ideas of your engineering team. Please reach us at sales@pvateplaamerica.com .

Our Technology

The video shows the principle and function of the diffusion bonding process and demonstrates the advantages of our furnace. Diffusion bonding allows metal parts to be joined without the use of filler materials. The patented process that PVA TePla has developed can combine to similar or dismilar metals to create a joint-free connection.

The advantages at a glance:

• A very high strength bond
• Joints that are not visible macro and microscopically one component is created
• No selective corrosion attack at the joint
• Large area connections with low material distortion can be realized
• Metallically bright components after the joining process
• Various material composites possible
• No liquid phase during the entire joining process
