瑞穂工業 List of Products and Services

We would like to introduce examples of processing using Mizuho Industry's unique "plate chocolate manufacturing method." Our customers faced challenges such as a high demand for comparing multiple insert shapes during the development stage, and the conventional mold manufacturing process being geared towards mass production, making it unsuitable for small lot production. After processing at our company, we significantly shortened the development lead time, allowing for efficient comparison and evaluation of multiple insert shapes. We were able to verify processing characteristics such as cutting resistance and chip discharge in advance during the small lot prototype stage. [Challenges and Background] - There is a high demand for comparing multiple insert shapes during the development stage. - Conventional mold manufacturing is based on mass production, making it unsuitable for small lot production. - Mold production requires time and cost, making it difficult to prototype multiple shapes within a short development lead time. - Insufficient design verification and cutting evaluation led to decreased development efficiency. *For more details, please download the PDF or feel free to contact us.*

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.*

Have you ever struggled with the brittleness of hard alloys? Powdered high-speed steel cannot withstand wear, but conventional carbide tools suffer from chipping. To respond to such voices from the field, Mizuho Industry developed "GF24." GF24 is a special grade that combines ultra-fine tungsten carbide particles of less than 0.6μm with a high binder design of 24%. This results in: - High hardness of HRA88.0 - High fracture toughness of 15.0 MPa·m¹ᐟ² - Compressive strength of 4.2 GPa - Toughness with a bending strength of 3800 MPa.
