ZNG Medical
Explore our ISO 13485 and CE certified clinical hardware engineered for accurate delivery, diagnostic sampling, and transdermal therapeutic compatibility.
Founded in 1996, Zhejiang ZNG Medical has established itself as an international benchmark in the research, engineering, and automated production of advanced parenteral and transdermal administration technologies. Operating with full adherence to ISO 9001 and ISO 13485 quality management systems alongside European CE mark certifications, our state-of-the-art industrial infrastructure turns complex active pharmaceutical ingredients (APIs) and mechanical delivery requirements into scalable commercial solutions.
Our Core Expertise: We specialize in custom OEM/ODM development of precision delivery mechanisms, specialized hypodermic & micro-needle arrays, spinal needles, epidural needles, Huber needles, fistula needles, microcannulas for cosmetic dermal fillers, automated biopsy devices, and contract transdermal patch manufacturing. By uniting material science, skin flux kinetics, and automated cleanroom assembly, ZNG Medical provides global pharmaceutical partners with guaranteed therapeutic bio-availability and regulatory security.
Understanding the bio-mechanical mechanics, skin flux optimization, and formulation architecture of next-generation transdermal platforms.
Our single-layer and multi-layer DIA matrix systems incorporate APIs directly into medical-grade pressure-sensitive adhesives (PSA) like acrylic, silicone, or polyisobutylene (PIB). This architecture offers superior physical flexibility, thin profiles, uniform skin contact, and controlled drug release rates driven by solid-state chemical concentration gradients.
Designed for potent therapeutics requiring zero-order kinetic release profiles. Featuring a dedicated liquid or gel active core separated from skin tissue by an ultra-precise microporous polymeric membrane (polyethylene or ethylene-vinyl acetate). Provides constant flux rates over extended wear periods (up to 7 days).
Bridging hypodermic delivery and classical transdermal patches. Our micro-projection arrays penetrate the stratum corneum barrier (100–1000 µm deep) without contacting dermal pain receptors. Compatible with biologic macromolecules, peptides, vaccines, and hydrophilic active compounds.
Key market factors driving the shift toward non-invasive continuous delivery technologies.
Overcoming the skin stratum corneum barrier for large molecular weight peptides, monoclonal antibodies, and mRNA through active iontophoresis and coated microneedle platforms.
Replacing daily oral dosing regimens or painful repeated intravascular injections with once-weekly sustained-release transdermal patches, dramatically reducing GI side-effects and peak-to-trough plasma fluctuations.
Combining active micro-fluidic channels with electronic continuous glucose monitor (CGM) biosensors for automated, closed-loop transdermal therapeutic adjustments based on real-time physiological telemetry.
Developing hypoallergenic skin contact adhesives featuring zero skin irritation, moisture-vapor breathability, clean peel characteristics, and stable adhesion under extreme environmental humidity.
How Zhejiang ZNG Medical leverages integrated industrial clusters to deliver unmatched scalability, precision quality, and cost efficiency.
From custom high-precision mold engineering and automated high-speed needle sharpening to polymer adhesive slitting and high-barrier pouch packaging, our full vertical integration reduces OEM development lead times by up to 45% compared to Western competitors.
Located in the heart of Zhejiang’s medical device industrial hub, we command immediate access to ultra-pure medical grade stainless steel (SUS304/SUS316L), medical silicones, non-woven backings, and fluoropolymer release liners audited under rigorous USP Class VI standards.
By coupling automated robotic assembly with high-volume procurement scaling, ZNG Medical enables global buyers to achieve substantial unit cost economies without compromising on ISO/CE regulatory compliance or batch-to-batch consistency.

Addressing essential technical, procurement, and customization queries regarding our transdermal systems and needle products.
Our Drug-in-Adhesive (DIA) and matrix transdermal platforms are compatible with low-molecular-weight, lipophilic active compounds across pain management (fentanyl, buprenorphine, lidocaine), central nervous system disorders (rivastigmine, rotigotine), hormone replacement therapies (estradiol, testosterone), and cardiovascular conditions (nitroglycerin). Custom permeation enhancer formulations can be engineered for specific flux targets.
Yes. We provide complete OEM/ODM customized needle engineering based on client drawings or samples. We can customize outer diameters (gauge sizes from 14G to 34G), cannula length, bevel geometry (3-bevel vs. 5-bevel, lancet point, blunt), wall thickness (regular wall, thin wall, ultra-thin wall), hub materials, and color coding compliant with ISO 6009 standards.
All automated assembly, primary pouch sealing, microcannula production, and drug-loading operations take place inside validated ISO Class 7 (Class 10,000) and ISO Class 8 (Class 100,000) cleanrooms. These facilities maintain continuous positive pressure, HEPA filtration, strict particulate monitoring, and microbiological bio-burden controls.
We provide free pre-production samples for physical verification, dimension matching, and lab testing. Upon receiving your technical parameters or reference samples, our engineering team manufactures prototype units within 7-14 business days, complete with initial inspection reports for client sign-off before mass production begins.
