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.*

【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.
