Product Description: Insulin Injection Needles Insulin injection needles are designed with ultra-fine and short needles. The 30-34G fine gauge smoothly penetrates the subcutaneous tissue, reducing pain and subcutaneous bleeding. The lengths range from 3mm to 12.5mm, with a focus on the mainstream 4mm and 6mm, minimizing the risk of accidentally injecting into the muscle and enhancing safety.

Company information
Sayama Mold Manufacturing designs and builds precision micro molds and carries out injection molding and volume production in-house. Because both mold making and molding are under one roof, we can propose the optimal part geometry from a mold engineer's point of view - not merely a shape that happens to be moldable. We supply manufacturers in Japan and overseas in the medical device, biomedical, optical communication, semiconductor and connector fields. We handle micro parts that require accuracy on the order of ±1 μm, and mold super engineering plastics and other difficult materials stably, which helps reduce defects and shorten lead times in volume production. We have built more than 2,200 molds over our 60-year history. ▼Track record / Certifications▼ 2002 ISO 9001 certified 2006 ISO 14001 certified 2021 Developed a PEEK resin injection needle (patent pending) 2022 Grand Prize, Tama Blue Award (Technology & Product category), 20th Tama Blue Green Awards 2024 Selected as one of the "300 Vibrant SMEs and Small Enterprises" (FY2023, Japan SME Agency)
