Japanese stainless steel manufacturer Nippon Kinzoku Co., Ltd. has announced the start of mass production of ultrathin and narrow-width stainless steel optimized for laser welding of ultrathin insulin needles, which ensures a stable supply chain in response to growing global demand.
The company said there is a growing demand for high-density insulin. Demand for needles is growing as manufacturers seek to reduce pain and bruising during injections. Ultrathin needles weighing 30, 31, and 32 grams are becoming more widely used, helped by the growing use of compact syringe pens and weight loss medications that also use ultrathin needles.
New materials contribute to the transition to laser technology сварку
According to Nippon Kinzoku, insulin needle tubes are traditionally made of 0.2mm thick material using TIG welding or plasma welding followed by repeated stretching and heating treatment to achieve the required dimensions.
However, manufacturers are increasingly using laser welding to meet the growing global demand. This technology allows for a significant increase in welding speed while using base materials that become thinner at the initial stage of production by more than 50%.
After testing with leading manufacturers, Nippon Kinzoku has mass-produced materials with a typical thickness of only 0.08mm and a width of 6.3mm, compared to a thickness of 0.2mm and a width of 12.8mm for typical TIG and plasma welding materials.
The company aims at stable production of ultrathin игл
Nippon Kinzoku stated that its new material ensures controlled edge quality, which minimizes welding defects and ensures stable weldability of rolls up to 4,000 mm long. meters. The product also offers the high-precision thickness and width tolerances required for high-speed laser welding and sufficient adaptability to produce ultra-thin needles without breaking.
The company already supplies specialized stainless steel NK-304NKM for thin-walled welded pipes used in the medical and cosmetic industries. applications, in particular, so-called painless needles.
