瑞穂工業 Company Overview

We manufacture and sell carbide tools and carbide molds. Please also try our special surface treatment, which is different from the SurmoX coating.

Mizuho Kogyo Co., Ltd. has been a rare manufacturer of carbide tools and various molds since its establishment in 1944, continuing the production and sales of carbide tools for over 80 years. We also offer special surface treatments such as welding rods "Triamant" and "SurmoX treatment." The "SurmoX treatment" does not cause dimensional changes before and after processing due to its coating-free nature, and it can be applied to brazed items and interference fits due to its low-temperature process. Additionally, it can be applied to deep internal diameters where conventional coatings were not possible. This is expected to prevent seizure and adhesion, as well as improve the release properties of powder molding molds. In recent years, we have also been able to manufacture inserts for development projects and small-lot special-shaped inserts in a short delivery time using a method called "plate chocolate manufacturing." Furthermore, please trust Mizuho Kogyo for OEMs of carbide holders with brazing or direct taps, as well as for spot products.
