Specialised in the research and development of injection syringes, special structure syringes and shaped needles, suitable for minimally invasive interventions, targeted therapies and other fine-tuned scenarios. Adopting high-precision CNC machining process, we customise the production of more than 30 types of shaped structures, such as side-hole needles, blunt-tipped needles, knife needles and so on. The needle body is made of medical grade SUS304 stainless steel and biocompatible coating, and is precision processed to ensure zero burr. Support 0.15mm-4.0mm ultra-wide inner diameter customisation, to achieve multi-functional integration of drug delivery, tissue collection, liquid aspiration, etc.
Zhejiang INI Medical Devices Co., Ltd., founded in 1987, is a state-certified manufacturer specializing in sterile medical devices, including disposable insulin syringes. Between 2009 and 2019, to meet growing market demand, the company significantly expanded its operations by investing over RMB 100 million in a new facility within Wenzhou Yongqiang High-tech Park. The site spans a total construction area of approximately 26,000 m², which includes an 8,000 m² 100,000-class clean workshop.
Our manufacturing infrastructure is tailored to the scale and requirements of medical device production. It features advanced equipment, spacious production and storage areas, and a controlled cleanroom environment. We uphold a rigorous quality management system, enforcing strict control over every production step. This is supported by a fully equipped and qualified inspection department with comprehensive testing capabilities appropriate for our production scale.
The company has established a quality assurance system in accordance with YY/T 0287-2017 / ISO 13485:2016, achieving certification through the internationally recognized TUV agency. This certification grants us the CE mark, affirming compliance with European Community standards.
Committed to continuous innovation and improvement, we strive to exceed regulatory and customer expectations. Our goal is to be recognized as a leading manufacturer with a strong corporate image and brand reputation. We sincerely welcome partnerships with domestic and international medical institutions to jointly contribute to the cause of global health.

Read moreINI as a medical device manufacturer with experience in precision components, we produce a range of cannula-type needle assemblies, including Needle Cannula, Hypodermic Cannula, and Dermal Cannula. These components serve multiple roles in injection systems, drainage systems, sampling lines, and minimally invasive device kits.
A Needle Cannula typically refers to a hollow, tube-like device that may include a blunt or pointed tip, designed to act as a conduit for fluids or injectables. Unlike a simple solid hypodermic needle, a cannula provides a passage for fluid movement. In many designs, the cannula can function as a sheath, extension, or interface element. We integrate Needle Cannula designs in various medical devices where controlled fluid delivery or extraction is needed.
As a manufacturer, we process tubes by drawing, polishing, precision cutting, and bonding to hubs or connectors. We consider inner diameter, wall thickness, tip geometry, and surface finish when designing a Needle Cannula, to balance fluid flow resistance and structural strength.
A Hypodermic Cannula is a type of cannula intended to penetrate skin or tissue, carrying fluids or providing access pathways. In essence, it's a hollow needle designed for percutaneous access. It combines the functionality of a hollow-bore needle with the geometry of a cannula. Manufacturers producing Hypodermic Cannula must ensure tip sharpness, wall uniformity, and mechanical resilience. Our production includes grinding, electro-polishing, and precise beveling to maintain consistency. In cleanroom conditions, Hypodermic Cannula parts are cleaned, dried, and assembled to polymer hubs or connectors to produce final devices.
A Dermal Cannula is a subtype of cannula typically used closer to or within dermal or subdermal layers. It often features a fine gauge, smooth blunt or semi-blunt tip, or gentle bevel for superficial insertion. Dermal Cannula products are used in cosmetic, dermatologic, or aesthetic delivery systems. In manufacturing, we apply extra polishing and quality checks to ensure minimal surface defects, smooth lumen, and reliable compatibility with micro-injectors or delivery devices.
Q1: As a manufacturer, what range of specifications do you support for these cannula-needle components?
A: We offer a wide range of inner and outer diameters, wall thicknesses, lengths, tip styles (bevel, blunt, taper), and hub interfaces. Whether Needle Cannula, Hypodermic Cannula, or Dermal Cannula, we tailor dimensions to match flow requirements, insertion depth, and device compatibility. We also support custom hub geometry, color coding, and connector interfaces.
Q2: How do you ensure consistency and surface quality?
A: We enforce tight tolerances on tube straightness, diameter, and wall thickness. After cutting and beveling, we polish the inner and outer surfaces (mechanical, electropolishing) to reduce burrs and micro-defects. We perform visual inspection, roundness measurement, and leak / flow testing. During assembly, bonding or welding to polymer hubs is done in controlled clean zones.
Q3: Are your cannula products provided in sterile, single-use form?
A: Yes. We supply Needle Cannula, Hypodermic Cannula, and Dermal Cannula devices as disposable single-use units. Each device is individually packaged, sterilized (commonly via ethylene oxide or gamma), and sealed to maintain sterility until use. We maintain documentation and validated sterilization protocols.
Q4: What role do these cannula components play in device systems?
A: In a broader medical device, a Needle Cannula or Hypodermic Cannula may serve as the fluid path between a syringe and tissue, or link a catheter to an infusion line. A Dermal Cannula might integrate with micro-injection or aesthetic delivery systems. As component suppliers, we design them to interface reliably with accessory parts such as Luer connectors, tubing, or injector modules.
Q5: Can customization and OEM work be supported for specialized applications?
A: Certainly. We provide OEM/ODM services, adapting Needle Cannula, Hypodermic Cannula, and Dermal Cannula designs to client needs. Whether unique hub shapes, specialized fittings, labeling, or packaging formats, our toolroom and R&D teams can prototype and validate new variants within agreed timelines.
Q6: How do you mitigate manufacturing risks in such fine tubing components?
A: Key challenges include maintaining tip sharpness without burrs, dimensional consistency, and leak integrity. We mitigate these by rigorous supplier qualification, inline inspections, redundant tooling, calibration of equipment, process validations, and statistical process control.
As a manufacturer of medical device components, our Needle Cannula, Hypodermic Cannula, and Dermal Cannula offerings represent specialized solutions for fluid delivery, access, and interfacing in injection systems.
