Water is circulated inside a metal plate to cool the entire plate, and a heating element is attached to absorb heat. This is mainly used for cooling semiconductor devices such as IGBTs, as well as for various applications and industries including UV-LEDs, amplifiers, and Peltier elements. The performance of water-cooled heat sinks varies significantly depending on the flow path structure and the machining precision of the element surface. Our company is committed to designing flow paths that efficiently and uniformly cool the surface, and we design and manufacture water-cooled heat sinks that meet your desired performance and shape.

The "Insulation Pipe Series" is an insulation pipe used in environments where heat resistance and corrosion resistance are required. Both ends of the ceramic pipe (ceramic tube) are hermetically bonded to a cylindrical metal, and the ceramic pipe and cylindrical metal are joined by metallization. It can be used in applications that require insulation and high airtightness. 【Features】 ■ Ceramic insulation pipe with excellent heat resistance and corrosion resistance ■ Excellent corrosion resistance to pure water, with many achievements as piping for pure water ■ High corrosion resistance, with many achievements in applications that transport gas ■ Customization of ceramic dimensions and fitting materials is also available ■ Non-magnetic types can also be produced "Insulation Pipe Spiral" Ideal for suppressing discharge generation during process gas introduction! This is a type of insulation pipe with spiral holes processed into ceramics. By adopting a spiral shape, it can suppress the occurrence of linear discharges. Additionally, unlike a simple straight pipe design, it can secure a longer insulation distance while maintaining the same overall length. *For more details, please refer to the external link page or feel free to contact us.

Our brazed products can join ceramics to metals through Kovar, copper, titanium, and aluminum after the ceramics have been metallized. In addition, we also perform brazing of dissimilar metals (such as copper to copper, aluminum to aluminum, copper to tungsten, beryllium to SUS or nickel or aluminum, aluminum to SUS, etc.), so please feel free to consult us. There are also cases where brazing is done with SUS (304, 316), etc. 【Brazing of Dissimilar Metals】 ■ Brazing of Beryllium ■ Brazing of Tungsten ■ Brazing of carbon-based materials (such as diamonds) to SUS ■ Brazing of copper to stainless steel *For more details, please refer to the PDF document or feel free to contact us.

The new transportation system refers to a medium-scale transport system that plays an intermediate role between railways and buses, serving as a means to connect development areas along the coast (new urban centers) with existing urban areas. Examples include "Yurikamome" (Tokyo) and "Port Liner" (Kobe). In coastal areas, there are impacts from salt damage, which can reduce the insulation performance of standard insulators. Kawaso Texcel offers salt-resistant and dust-resistant (double skirt type) insulators that have a proven track record in the steel industry, ensuring the safety of the new transportation system over the long term.

Our company has been developing and selling wire fuses as equipment to protect power lines for electric companies since 1976, to deliver electricity to various consumers. In 1997, we began considering the elimination of lead from our products from an environmental protection perspective, and started the development of lead-free wire fuses. In this consideration for lead-free development, instead of replacing the lead contained in low-melting alloys with another metal, we started examining the feasibility of a copper-integrated structure that eliminates the soldered connections, which are a factor in the aging deterioration of the elements, to create a product that is resistant to aging deterioration. 【Features】 ■ Copper-integrated design with no connections, significantly extending lifespan against long-term deterioration ■ Easy visual assessment of operational status ■ Completely free of lead, environmentally friendly product *For more details, please refer to the external link page or feel free to contact us.
