Focusing on the field of insulin injection, we strictly follow the ISO13485 system to produce single-use insulin syringes and single-use insulin pens with matching injection needles.
Adopting high-precision triple-scaled and viewable window design (29G/30G/31G optional), together with ultra-thin-walled syringes and laser-cut five-cut tips, they can achieve 0.01ml precise drug delivery and painless puncture.
All the products are double ethylene oxide sterilised, each one is sealed and packed individually, equipped with safety caps, and are suitable for a variety of mainstream brands of insulin pens.
They can be used for the daily management of diabetic patients and the treatment of chronic diseases in medical institutions, guarding the safety of precise drug delivery every time.

Read moreINI as a specialized producer in the medical device industry, our company has devoted years of development and production experience to supporting global Diabetes Care solutions. Among the essential components we manufacture are Insulin Syringes and Insulin Needles, which play an important role in daily diabetes management for patients and healthcare providers worldwide.
The global Diabetes Care sector continues to grow due to the increasing demand for convenient, reliable, and single-use injection systems. Insulin Syringes and Insulin Needles represent a major portion of this demand, as they are critical tools used by individuals who require insulin delivery. For manufacturers like us, the challenge lies in ensuring that every product meets strict medical-grade quality standards while remaining user-friendly and cost-efficient for large-scale production and distribution.
Each Insulin Syringe typically consists of three major components: a transparent barrel, a plunger with a smooth-sealing rubber tip, and a fine-gauge Insulin Needle attached to or integrated with the syringe hub. The barrel is marked with clear, permanent graduations for accurate dose measurement. As manufacturers, we use high-clarity polypropylene and medical-grade elastomers to ensure consistent quality and chemical resistance.
The Insulin Needle is designed to be ultra-fine, polished, and precisely ground to minimize resistance during penetration. Standard gauges commonly range from 28G to 32G, with lengths between 4mm and 12mm, depending on application requirements. The assembly of the Insulin Syringes and Insulin Needles is carried out in a cleanroom environment to maintain sterility and dimensional integrity.
From a production standpoint, every Diabetes Care injection device follows a strict sequence of manufacturing and inspection:
Throughout this process, automated visual inspection and mechanical testing are conducted to confirm product uniformity, smooth plunger movement, and secure needle attachment.
To meet diverse customer requirements, we offer customized Insulin Syringes and Insulin Needles with different specifications, volumes, and hub colors. OEM and ODM services allow clients to tailor labeling, packaging, and branding. Our factory operates multiple automated production lines capable of manufacturing millions of units monthly, ensuring reliable supply for both domestic and international Diabetes Care markets. Efficient logistics and robust quality control allow us to maintain steady long-term cooperation with medical distributors and device integrators.
As a manufacturing enterprise, our mission is to deliver Insulin Syringes and Insulin Needles that combine engineering precision with strict hygiene standards. We continuously invest in tooling optimization, automated assembly, and quality traceability systems to enhance consistency and production efficiency. In the evolving Diabetes Care sector, we believe that manufacturing excellence, regulatory compliance, and continuous improvement remain the foundation of customer trust.
