We will introduce examples of how stable processing quality has contributed to reducing defect rates and improving yield!
We would like to introduce a case study of the surface modification technology 'SurmoX' that can address the deep areas of deep drawing molds. In this case study, deep drawing processes for automotive and precision parts often face issues where friction and adhesion easily occur in the inner diameter of the mold die. Conventional coatings struggle to uniformly reach the deep inner diameter, leading to a higher likelihood of seizing during processing. By applying our technology, we successfully reduced seizing and adhesion significantly, resulting in decreased frequency of mold replacement and extended lifespan. This led to a reduction in maintenance labor and total costs, thereby improving productivity. [Challenges and Background] - In deep drawing processes for automotive and precision parts, friction and adhesion are likely to occur in the inner diameter of the mold die. - Conventional coatings have difficulty uniformly reaching the deep inner diameter, making seizing during processing more likely. - The lifespan of molds is shortened, leading to frequent maintenance and replacement costs as challenges. *For more details, please download the PDF or feel free to contact us.*

basic information
【Summary of Other Cases】 ■Solution (Application of SurmoX) - Stable processing is possible even in deep internal diameters that were previously difficult. - A high-durability modified layer is formed on the surface, reducing direct contact between metals. - Compared to coating, the uniformity of processing is higher, ensuring effectiveness even in deep areas. ■Results and Effects - Significant reduction in seizure and adhesion has been achieved. - The frequency of mold replacement has decreased, resulting in longer lifespan. - This leads to a reduction in maintenance labor and total costs, improving productivity. - Stable processing quality contributes to a reduction in defect rates and improvement in yield. *For more details, please download the PDF or feel free to contact us.

Company information
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.
