Yamato Chemical completed a full renovation of the clean room on the first floor of its headquarters' second factory in March 2019, and operations began in April. The clean room specification complies with ISO Class 8 (Class 100,000). By establishing a system that allows for the completion of processes from injection molding to finishing, processing, inspection, and packaging within the clean room, we aim to maintain more stable quality. Additionally, along with this renovation, we have also expanded our silicone rubber injection molding machines, thereby enhancing our production capacity compared to before. 【Features】 ■ Clean room specification: ISO Class 8 compliant (Class 100,000) ■ A system that allows for the completion of processes from injection molding to finishing, processing, inspection, and packaging within the clean room ■ Enhanced production capacity compared to before 【Product Examples】 ■ Sealing rubber for three-way valves ■ Gaskets for syringes ■ O-rings for medical devices ■ Neo-feed caps ■ Check valves ■ Silicone couplers for medical devices *For more details, please refer to the PDF materials or feel free to contact us.
