Corporate
Profile

[Company strength]
As a comprehensive diffusion bonding manufacturer, we can supply parts and products under a one-stop service from trial manufacturing to mass-production. We mass-produce diffusion-bonded parts and products and reduce the cost of these parts and products by using diffusion bonding equipment developed and designed in-house, diffusion bonding process management, a quality assurance system, and line automation technology. We stably supply parts and products to a wide variety of fields including the auto industry as well as fields associated with semiconductor manufacturing machines, food production machines, industrial machines, electricity and electronics, and special measurement hardware.

[Business description]
We provide high-precision diffusion bonding technology based on bonding equipment designed and manufactured in-house, as well as design technology and process management. We produce special 3D structure parts using diffusion bonding technology and performing everything in-house, from research and design to simulation, analysis, prototype making, and manufacturing. We also develop, manufacture, and sell thermal heat control parts such as heat exchangers and heat sinks, which are products made using diffusion bonding.

[Industry]
Metal processing

[Strength of products/technologies]
We are engaged in the research and manufacturing of 3D structure parts and products that cannot be achieved by conventional methods and that have micro structures. We conduct in-house the evaluation of materials to learn about the diffusion bonding process (microscopic observation, strength tests, SEM, EDX, with ultrasonic flaw detectors, thermal shock testing machines, etc.), and the calculation and evaluation of thermals fluid after completing the functional parts. We can provide standard products including heat exchangers, water-cooling heat sinks, and sheet heat pipes as products developed and designed in-house. Our products are widely used in various fields related to automobiles, electricity, semiconductors, industrial machines, and food production machines.

[Representative's message]
We are proud to deliver new functions, high performance, and multifunctions. We have attained high performance, size reduction, energy conservation, multifunctions, high efficiency, and high withstanding pressure of parts by means of diffusion bonding technology. We strive to adopt promising concepts on the basis of research, analysis, and evaluation. It is sometimes difficult to address the challenges from leading-edge academic societies, industries, and companies, but nonetheless we are determined to satisfy both engineers (creators) and users and create memories for them. We seek to be a reliable partner for customers.

[Market share/Ranking]
We have a 20% market share, and rank No. 2 in the industry.
