We would like to introduce examples of injection-molded products related to "automotive components" that our company has produced. For "fuel components," we maintain high quality through product shape proposals that emphasize product strength and quality control that understands product applications. For "electronic components," we have achieved cost reduction in mass production line processes by incorporating considerations for high productivity molds (multiple cavities and high cycle times), which has pleased our customers. In addition, we have numerous manufacturing examples of safety and security components, as well as optical components. For more detailed information, please refer to the PDF download below. [Case Overview (Partial)] <Fuel Components> ■Field: Automotive ■Materials: PPS, PA, POM, etc. (including GF) ■Established a management system to prevent contamination in a clean molding environment ■By managing resin molded components at the micrometer level, we provide peace of mind to our customers *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study of mold manufacturing in the medical field that we conducted. The "syringe (disposable syringe, pre-filled syringe)" was successfully produced with a mold that increases the production quantity per unit time by increasing the number of cavities while using existing molding equipment, thereby reducing product costs. We also have case studies for other products such as "gaskets," "dialyzers," and "petri dishes (stacked 16+16)." 【Case Overview】 ■ Product: Syringe (disposable syringe, pre-filled syringe) ■ Resin Materials: PP, COP, COC ■ Number of Cavities: 16 to 48 *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study on the production of molds for caps and containers that we conducted. Caps are products with a very low unit price, making it difficult to generate profit without mass production, so we were consulted on proposals to reduce costs. Since dynamic assurance of multi-stage punching and accumulated mold design know-how are required, we participate in product design reviews from the development stage and carry out mold production considering flow analysis and weld countermeasures. Additionally, we have a case study on the production of "food containers," which presents the challenge of how to reduce product costs, as they are products that require mass production. *For more details, please refer to the PDF materials or feel free to contact us.
