YOMURA JAPAN Office (Opereted by Minnano Modeling Service) Product Lineup

We would like to introduce the "two-color molding" that we handle. This is a technology that allows for the integrated molding of two types of materials or colors in a single molding cycle. By combining resins with different hardness, colors, and materials, it is possible to manufacture composite parts that previously required assembly as a single unit. It achieves a strong integration of different materials and is also compatible with the integrated molding of grip and seal parts. 【Features】 ■ Cost reduction by reducing assembly processes ■ No adhesives required, ensuring biocompatibility ■ Strong integration of different materials ■ Integrated molding of grip and seal parts is possible *For more details, please download the PDF or feel free to contact us.

We received an inquiry from a medical device distributor in the United States regarding the development and mass production of a valve device that controls the flow of liquids, etc., with ON/OFF functionality. This product requires intuitive operation with one hand and IP58 waterproof performance to withstand use in medical environments. Additionally, achieving full compliance with FDA regulations while optimizing costs is a critical challenge. The annual production quantity is between 30,000 and 50,000 units, with a defect rate of 1 in 10,000. The mold production period is 35 to 45 days, and the mass production period is 2 years. 【Technical Challenges】 ■ Ensuring waterproof performance: Achieving stable IP58-level waterproof performance in mass production while maintaining precise fitting tolerances for slider components. ■ Compliance with FDA regulations: Establishing material selection, process management, and documentation systems in accordance with U.S. FDA regulations, and passing regulatory authority reviews. ■ Precision tolerance matching: Designing precise tolerances considering the thermal expansion differences between materials in two-color molding and stabilizing mass production. ■ Cost optimization: Achieving competitive cost targets while maintaining high-quality standards (defect rate of 1 in 10,000). *For more details, please download the PDF or feel free to contact us.

We received an inquiry from a major Taiwanese medical device brand manufacturer regarding the development and mass production of a spray-type inhaler for asthma patients. The cap components require high waterproof performance (IP58) and durability, with the main challenges being ease of use and reliability ensured by a unique hook and hinge mechanism. Strict requirements were also imposed on the speed of mass production startup and cost competitiveness. The annual production quantity is between 30,000 and 50,000 units, with a defect rate target of 1 in 5,000. The mold manufacturing period is 45 to 60 days, and the mass production period is 1.5 years. 【Technical Challenges】 ■ Ensuring waterproof performance: Achieving IP58 level waterproof performance for the cap components while maintaining mass production stability. ■ Complex structure molding: Accurately reproducing the special hook and hinge design through two-color molding (TPU on PC) and minimizing the assembly process. ■ Balancing quality and cost: Maintaining a high defect rate target (1 in 5,000) while ensuring cost competitiveness. ■ Speed of mass production startup: Rapid transition to mass production in line with the brand manufacturer's market launch schedule (mold manufacturing takes 45 to 60 days). *For more details, please download the PDF or feel free to contact us.
