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.

We will clearly explain the basic concepts for understanding the characteristics of each column and strategically selecting the most suitable column for your research and analysis purposes, along with practical selection points. We will also touch on column selection for GC/MS, aiming for a broader acquisition of knowledge. The choice of column is a crucial factor that influences the results of GC analysis. Commercially available columns have various features, such as the type of liquid phase, inner diameter, length, and film thickness. This is an excellent opportunity to deepen your understanding of GC columns, so please take a look.

Publication of a specialized analytical method for ultra-short-chain PFAS analysis, presented at the 59th Annual Meeting of the Japan Society of Water Environment (March 2025)!

Tokyo, August 14, 2025 - (JCN Newswire) - Global consulting firm AlixPartners (hereinafter referred to as "the Company") has conducted a survey of industry experts involved in turnaround and restructuring in Asia and has released the latest report titled "2025 Asia Turnaround & Restructuring Survey" (hereinafter referred to as "the Survey"). The results of this survey indicate that, amidst ongoing geopolitical tensions affecting the economic situation, there is an optimistic outlook in Asia regarding global market instability and uncertainty. On the other hand, over 90% of respondents predict that geopolitical turmoil, such as regime changes and conflicts, will lead to an increase in corporate underperformance in the Asia region. Additionally, about 70% believe that global supply chain challenges will worsen over the next year, indicating that as international circumstances become more complex, the impact of such changes on Asian businesses is expanding.
