DRAGON ETCHING TECHNOLOGY., LIMITED, commonly referred to as DRAGON ETCHING, has established itself as a premier provider of chemical etching solutions for the medical device industry. With a focus on precision, reliability, and innovation, the company supports the production of critical components used in surgical instruments, implantable devices, diagnostic equipment, and more. Leveraging over a decade of experience and state-of-the-art facilities, DRAGON ETCHING transforms complex designs into high-accuracy metal parts that meet stringent regulatory standards.

Chemical etching, also known as photo etching or chemical milling, is a subtractive manufacturing process that uses photoresist and chemical etchants to create intricate patterns in metal. This technique offers distinct advantages for medical devices, including burr-free edges, no heat-affected zones, and the ability to produce fine features with tight tolerances. DRAGON ETCHING specializes in a wide range of materials, such as stainless steel, titanium, nitinol, copper, and aluminum alloys, ensuring compatibility with biocompatible and corrosion-resistant requirements.

Key Capabilities for Medical Device Production

Precision and Tolerance Control

DRAGON ETCHING achieves tolerances as tight as ±0.001 inch (0.025 mm) depending on material thickness and geometry. This level of precision is essential for components like stents, catheter tips, surgical blades, and electrode arrays. The company employs advanced imaging systems and automated inspection to verify dimensions, ensuring each part meets design specifications.

Material Expertise

The company works with over 50 metal alloys, including medical-grade stainless steels (304, 316L, 17-7PH), titanium (Grade 1-5), nitinol (shape memory alloy), and precious metals like platinum and gold. All materials are sourced from certified suppliers, and DRAGON ETCHING maintains full traceability from raw material to finished product.

Scalability from Prototype to Production

Whether a client needs rapid prototyping for a new device or high-volume manufacturing for commercial launch, DRAGON ETCHING offers flexible production capabilities. The factory houses multiple etching lines capable of processing sheets up to 24x24 inches, with annual output exceeding 10 million parts. Quick-turn prototypes can be delivered in as little as 3-5 business days.

Quality Management and Regulatory Compliance

DRAGON ETCHING is ISO 9001:2015 and ISO 13485:2016 certified, demonstrating commitment to quality management systems for medical devices. The company follows stringent process controls, including statistical process control (SPC), first article inspection (FAI), and in-process monitoring. Cleanroom facilities (Class 10,000) are available for sensitive components, and all production meets RoHS and REACH compliance.

For implantable devices, DRAGON ETCHING provides documentation packages that include material certifications, process validation reports, and dimensional inspection data. The company also supports biocompatibility testing per ISO 10993 requirements.

Applications in Medical Devices

Chemical etching is used to manufacture a variety of medical components, such as:

• Surgical instruments: Scalpel handles, forceps tips, scissors, and retractors.

• Implantable devices: Stents, bone plates, mesh, and electrode arrays.

• Diagnostic equipment: Microfluidic chips, sensor electrodes, and filter membranes.

• Catheters and delivery systems: Hypotubes, guidewire components, and drug delivery ports.

For example, DRAGON ETCHING produces precision stents from nitinol or stainless steel with laser-marked alignment features and polished surfaces. The process enables complex geometries like cell patterns and tapered sections without secondary machining.

Advanced Technologies and Innovation

DRAGON ETCHING continuously invests in technology to enhance capabilities. The company uses digital phototooling for high-resolution imaging, enabling feature sizes down to 0.002 inch. Proprietary etching chemistry ensures uniform metal removal and consistent edge quality. Additionally, the R&D team collaborates with clients on process development for new alloys or unique geometries.

The company also offers complementary services like electroplating, passivation, laser welding, and assembly. This integrated approach reduces supply chain complexity for medical device manufacturers.
