NIPPON KINZOKU Scales Ultra-Thin Stainless Steel for Insulin Needles
Event summary
- NIPPON KINZOKU began mass production of 0.08mm stainless steel for laser-welded insulin needles on August 26, 2026.
- New process enables 50% thinner base materials compared to traditional TIG/plasma welding methods.
- Materials achieve 4,000-meter coil stability with ±0.002mm thickness tolerances.
- Developed in collaboration with global insulin needle manufacturers.
The big picture
The shift to laser welding represents a critical inflection point in insulin needle manufacturing, enabling thinner gauges while reducing production costs. NIPPON KINZOKU's move positions it as a potential supplier to major diabetes care companies like Novo Nordisk and Sanofi. The global insulin pen market is projected to grow at 6.8% CAGR through 2030, creating significant demand for advanced materials.
