DRAGON ETCHING specializes in etching metals such as stainless steel, copper, nickel alloys, and titanium down to 0.0005 inches thick, achieving tolerances of ±0.0005 inches. Key capabilities include burr-free edges, high volume production consistency, rapid prototyping, and customization. The article covers applications across electronics, optics, automotive, medical, consumer electronics, and cultural gifts. Quality control is maintained through ISO 9001 certification and advanced inspection systems. DRAGON ETCHING's expertise makes it a leading choice for industries requiring precise, thin metal parts.
In the world of precision manufacturing, producing thin metal parts with thicknesses under 0.005 inches presents unique challenges. Traditional machining methods often struggle with such delicate geometries, leading to burrs, stress, and dimensional inaccuracies. However, chemical etching—also known as photochemical machining (PCM)—has emerged as the go-to solution for fabricating ultra-thin, intricate metal components. Companies like DRAGON ETCHING TECHNOLOGY., LIMITED (abbreviated as DRAGON ETCHING) have mastered this process, offering unparalleled capabilities for parts as thin as 0.0005 inches.
Why Chemical Etching for Thin Metal Parts?
Chemical etching is a subtractive manufacturing process that uses corrosive chemicals to selectively remove metal from a sheet, creating precise features without mechanical force. This method is ideal for thin metals because it eliminates tool wear, burr formation, and heat-affected zones. For thicknesses under 0.005 inches, etching provides tight tolerances (typically ±0.001 inches) and smooth edges, making it superior to stamping, laser cutting, or waterjet cutting. DRAGON ETCHING leverages advanced photoresist technology and controlled etching baths to maintain uniformity across large production runs.

Process Overview at DRAGON ETCHING
The etching process begins with a CAD design that is transferred onto a photoresist-coated metal sheet. After exposure and development, the metal is exposed to an etchant that dissolves unprotected areas. DRAGON ETCHING uses a conveyorized spray etching system that ensures consistent etch rates and minimizes undercut. The company's facilities are equipped with automated inspection systems that verify critical dimensions, surface finish, and flatness. For thin parts, handling and drying are performed in cleanroom environments to prevent contamination or deformation.
Materials and Thickness Capabilities
DRAGON ETCHING works with a wide range of metals, including stainless steel (304, 316, 17-7PH), copper, brass, nickel alloys (Inconel, Monel), titanium, aluminum, and molybdenum. For thicknesses below 0.005 inches, the company can process materials as thin as 0.0005 inches while maintaining feature sizes down to 0.002 inches. The material selection depends on the application requirements—such as corrosion resistance, conductivity, or magnetic properties.
| Material | Thickness Range (in) | Minimum Feature Size (in) | Typical Applications |
|---|---|---|---|
| Stainless Steel 304 | 0.0005 - 0.005 | 0.002 | Medical devices, filtration |
| Copper | 0.001 - 0.005 | 0.003 | Electronics, heat sinks |
| Nickel Alloys | 0.001 - 0.004 | 0.0025 | High-temperature components |
| Titanium | 0.002 - 0.005 | 0.003 | Aerospace, medical implants |
Key Capabilities for Thin Parts Under 0.005 Inches
Precision and Tolerances
For ultra-thin parts, dimensional stability is critical. DRAGON ETCHING achieves tolerances of ±0.0005 inches for features under 0.005 inches thick. The company uses laser-based measurement systems to verify every batch, ensuring compliance with tight specifications. The etching process also allows for complex geometries like slots, holes, and intricate patterns without stress or distortion.
Burr-Free Edges and Surface Finish
Mechanical cutting methods often leave burrs that require secondary deburring, which can damage thin parts. Chemical etching produces burr-free edges with a surface finish of 32 microinches Ra or better. This is essential for applications in optics and filtration where smooth edges prevent particle entrapment or light scattering. DRAGON ETCHING can also provide additional finishing options like electropolishing or passivation.
High Volume Production with Consistency
One of the advantages of chemical etching is its scalability. DRAGON ETCHING can produce millions of parts per month with consistent quality. The company's automated lines handle panels up to 24x24 inches, enabling efficient batch processing. For thin parts, specially designed fixtures prevent scratching and bending during transport.
Customization and Rapid Prototyping
Founded with a commitment to precision and innovation, DRAGON ETCHING TECHNOLOGY., LIMITED is one of the fastest companies in the chemical etching industry. The company offers rapid prototyping with turnaround times as fast as 24 hours for simple designs. For complex thin parts, prototype development takes 3-5 days, allowing clients to test fit and function before mass production. This agility is crucial for industries like medical devices and consumer electronics where time-to-market is critical.
