Solid-phase diffusion bonding refers to [WELCON Corporation].

We are offering a free document that explains the features and methods of "diffusion bonding," a technology for joining metals without melting them! A must-see for manufacturing beginners!

Since our establishment, we have been working to adapt diffusion bonding technology for mass production, and we are pleased to present a detailed explanation of "diffusion bonding" from our company! The diffusion bonding we conduct is a solid-state bonding technique that joins metals without melting them, which broadens the range of feasible products and functions. For example: - High-pressure, compact, and high-performance heat exchangers (such as those for hydrogen stations) - Water-cooled heat sinks capable of uniform cooling - Vapor chambers (sheet-type heat pipes) that can diffuse localized heat input in a planar direction - Microreactors that efficiently mix minute amounts of two fluids Through the realization of fine and complex structures, we have been working on miniaturization and high performance. Please feel free to consult us, especially for any heat-related issues. This document clearly explains the principles, methods, and features of diffusion bonding! It is designed to be easy to read, even for beginners in manufacturing, using diagrams and photos. You can download the document immediately from "PDF Download." We encourage you to take a look! 【Contents】 - What is diffusion bonding? - Methods of diffusion bonding - Features of diffusion bonding

Capable of manufacturing complex fine three-dimensional structures! We have a proven track record in various fields such as aerospace and chemical plants.

Solid-phase diffusion bonding is a method of directly joining materials that are to be bonded, which is significantly different from techniques such as welding or brazing. By applying heat and pressure to the materials to be joined, this technique promotes atomic movement at the bonding interface, allowing for bonding without melting the materials. This solid-state bonding expands the range of possible manufacturing methods and functionalities. Through the method of solid-phase diffusion bonding, it is possible to create fluid devices with microchannel structures and complex fine three-dimensional structures. 【Features】 ■ Lamination bonding of thin plates is possible ■ Bonding strength comparable to the base material can be achieved ■ Complex hollow components can be manufactured ■ Precise bonding with minimal deformation is possible ■ Bonding of dissimilar materials is possible *For more details, please refer to the PDF document or feel free to contact us.
