Providing Key Components to Support Safe and Comfortable Society


Uchihashi Estec began manufacturing and marketing solder products in 1918. Since then, the company has been pursuing advanced special alloy processing techniques and applied technologies. Uchihashi Estec will soon celebrate its 100th anniversary. For nearly a century, the company has been spearheading the development of the most advanced alloy technologies – including the successful commercialization of the world’s first small alloy thermal-links – while helping improve product safety and reliability in the manufacturing industry.

Our thermal-links and solders may not always be visible to consumers, but they ensure the safe and reliable operation of a wide range of products in which they are incorporated. Meanwhile, by building on our customer-oriented approach and leveraging our technological expertise and innovation, we are providing optimal safety solutions for our partners to use in meeting the ever-increasing need for product safety and quality.

As we continue delivering advanced, high-quality key components to our customers, we at Uchihashi Estec are fulfilling our mission as a material and component manufacturer, maintaining customer trust and working to exceed their expectations for our products.
