We will be exhibiting at Techno Frontier 2024.

A must-see for those struggling with heat generation! Introducing uniform cooling and low refrigerant heat sinks.

Due to the increase in computational load and high output, the heat generated by chips and light sources has increased, and we often hear the following concerns: - Air cooling cannot sufficiently cool the high heat generation. - I want to try water cooling, but I wonder if it will leak. - Considering carbon neutrality, I want a cooling method that reduces environmental impact and power consumption. Therefore, we are releasing a brochure on heat sinks as a reference for considering water cooling! Please feel free to download the brochure.

• Heat exchanger

Introducing a heat exchanger for hydrogen compressors with a design pressure of 94 MPa and a heat resistance temperature of 190°C!

This time, we would like to introduce our high-pressure microchannel heat exchanger, the 'WEL-Cool(R) H2 Series,' which we are currently developing. It is a heat exchanger for hydrogen compressors that applies the technology of the heat exchanger H2C (pre-cooler) designed for hydrogen stations. Its rectangular shape makes it easy to install and contributes to space-saving. Additionally, we are developing two standard designs tailored for different applications: one for packaged hydrogen stations and another for medium-sized hydrogen stations. <Example of expected specifications> - Design pressure: 94 MPa - Heat resistance temperature: 190°C *For more details, please download the PDF or feel free to contact us.

We are currently offering a free document that clearly explains the features and usage of the heat dissipation device "vapor chamber," which can efficiently spread heat.

We are offering a clear explanatory document that introduces the "vapor chamber," which is suitable for cooling and heat dissipation in electronic devices, industrial equipment, and medical/testing equipment! A vapor chamber is a heat dissipation device that transports and spreads heat, allowing for efficient heat dissipation from various products. Due to its thin sheet form, it has recently been adopted in mobile devices compatible with 5G. This document provides an easy-to-understand explanation of the basics and features of vapor chambers! It includes diagrams and photos, making it accessible even for those who are unfamiliar with vapor chambers. You can download the document immediately from the "PDF Download" link. We encourage you to take a look! [Contents] - What is a vapor chamber? (3 pages total) - Features of vapor chambers (4 pages total)

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

On September 11, 2025, AC Tasarim, a cable blade manufacturer, and our company signed a sales agency agreement for Japan. This was also announced in the company's press release and on social media. Founded in Turkey in 2003, AC Tasarim manufactures flexible EMI cable shields (copper braid), polyester braid, meta-aramid braid (Nomex cable sleeves), flat copper braid busbars/ground braids, all AA59569-coded copper braids, and released AeroBraid in 2025, the world's lightest EMI braid. All manufactured copper braids are certified to military standards. AC Tasarim products hold key certifications including VDE/VG certification, German Federal Armed Forces certification, NATO NSN coding, AS9100 quality certification, and JOSCAR certification. Cable braids and EMI shielding products, essential for wire harnesses in the aerospace and defense industries, are becoming increasingly difficult to source as demand rises. TC Tasarim products are stocked by manufacturers and distributors to ensure quick response times.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without affecting the base material with heat. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

The "HM-S6" is an embedded park sensor that detects vehicles through changes in magnetic flux and can respond to various situations from passing to stationary. It can be used for the opening and closing of the input doors at waste treatment plants, as well as for gates where vehicles pass and in outdoor parking applications. It can also be installed on rebar and steel plates. 【Features】 - Resistant to the effects of natural environments such as rain, snow, temperature changes, and geomagnetism. - Protection rating IP68 reduces the risk of water ingress. - Ten times the load capacity compared to conventional embedded park sensors (according to our comparison). - Can distinguish between vehicles even when they pass continuously, one by one. - Can be installed on rebar and steel plates. *For more details, please refer to the PDF document or feel free to contact us.

The "CCS2" is a ceiling-mounted vehicle counting sensor that employs an infrared reflection method. It can detect vehicles in both directions with just one unit, accurately counting vehicles even during traffic jams or when vehicles pass each other. Additionally, this product can be used not only for vehicle counting but also as a sensor for departure warnings. Furthermore, by using a separately sold dedicated remote control, it is easy to reset the sensor alone, switch the counting direction, and change the patterns of the departure warning timer. 【Features】 ■ Angle adjustment is possible up to ±5° ■ Can be installed in locations with high ceilings up to 4m ■ Detection area consists of 40 spots, allowing for wide-range detection ■ The display LEDs are color-coded by direction, making operation confirmation easy.
