Surface treatment to prevent surface cracking due to thermal history of semiconductor devices and automotive parts.
"No cracks occur even at 200℃" - Contributes to improved yield and reduced frequency of parts replacement! *Catalog featuring case studies available.
"WELMITE" is a heat-resistant anodizing treatment developed in-house (anodic oxidation treatment of aluminum components). Typical anodized coatings can crack due to differences in expansion caused by the disparity in thermal expansion coefficients between the anodized layer and the aluminum substrate. This coating structure aims to alleviate the differences in thermal expansion, and no cracks occur even in a 200°C cycle test. In applications where parts such as semiconductor device components or automotive parts may become heated, it is possible to prevent surface cracking due to thermal history. We have included examples in our materials that demonstrate improvements in yield for semiconductor manufacturing equipment exposed to an installation temperature of 180°C.

Company information
We believe that our mission is to evolve and propose surface treatment technologies, which are foundational technologies for manufacturing, have a history dating back to ancient times, and have evolved to support cutting-edge industries of each era, but are now becoming skills that not everyone can perform. This evolution begins with communication with our customers. We learn about the materials our customers use, understand the required functional characteristics, and study the environment in which the finished products will be used and the roles they are expected to fulfill. If necessary, we collaborate with universities and public research institutions. We then provide the optimal surface treatment technology.
