Introduction

Nippon Kinzoku Corporation, headquartered in Tokyo, has recently announced the establishment of a mass production system for a novel type of stainless steel, specifically designed for laser welding in the manufacturing of insulin syringes. This initiative comes as a response to the surging global demand for more efficient and patient-friendly injection devices.

Global Demand for Insulin Injection Devices

According to the International Diabetes Federation (IDF), as of May 2025, the estimated number of adults living with diabetes worldwide has reached approximately 589 million, which equates to around one in nine adults. Projections indicate that this figure could escalate to 853 million by 2050, thus amplifying the demand for insulin injection devices significantly. Recent technological advancements in insulin delivery have prioritized reducing pain and minimizing bruising during injections, leading to a rising preference for ultra-fine needles, specifically sizes 30G to 32G.

Additionally, there is a notable increase in the adoption of compact, portable injection pens that facilitate self-administration. It is worth mentioning that similar ultra-fine needles are increasingly being utilized in the emerging market for obesity treatment drugs, further contributing to the burgeoning market for fine gauge needles.

Nippon Kinzoku's Market Position

Nippon Kinzoku plays a crucial role in meeting this growing need. The company's stainless steel, known as NK-304NKM, is recognized globally for its excellent weldability and superior drawing process characteristics. Currently, they maintain a leading market share of approximately 57% in Japan and about 55% in key global regions like Southeast Asia and Europe, thanks to the high quality and reliability of their products.

Transition to Laser Welding Technology

Traditionally, the manufacturing of insulin syringes relied on TIG and plasma welding techniques, which involved tube formation, drawing, and heat treatment processes for extremely thin tubes, typically with a material thickness of 0.2 mm. However, to meet the rapidly increasing demand, the industry is shifting toward laser welding technology, capable of producing thinner materials (down to 0.08 mm) at a faster rate.

In response, Nippon Kinzoku has invested in laser welding machines and has been collaborating with numerous clients to ensure the supply of high-quality, thin gauge materials suitable for laser welding. The introduction of this technology enables them to meet the quality and production demands of an expanding market both domestically and internationally.

Product Features and Advantages

The stainless steel designed for laser welding adheres to stringent quality management standards comparable to those used for conventional welding materials. Some of the unique advantages of Nippon Kinzoku's products include:

• - Superior Cutting Edge Quality: The company maintains a high level of control over edge quality, which is critical to minimizing welding defects.
• - Stable Long-Length Supply: The company provides uniform weldability across coils that can reach lengths of 4,000 meters.
• - High Precision in Dimensional Tolerances: They pursue optimal thickness and width tolerances to suit the precise specifications required for laser welding processes.
• - Excellent Formability: The material's ability to withstand extreme elongation without breaking ensures reliability in the production process.

Commitment to Innovation and Quality

Nippon Kinzoku's dedication to advanced manufacturing technologies underscores its commitment to fulfilling the evolving needs of the medical and aesthetic sectors. By leveraging its extensive experience in rolling and processing technologies, the company aims to address diverse market demands while supporting advancements in healthcare technology.
