MEDICAL DEVICES & INSTRUMENTS

In the high-stakes world of healthcare, the margin for error is non-existent. Medical devices—from the life-saving stents in a patient's artery to the precision scalpels in an operating theater—demand a level of manufacturing excellence that transcends standard engineering.

​

While traditional methods have served the industry for decades, a more refined approach is taking center stage: Chemical Etching. At Metching, we provide medical device designers with a rapid, clean, and cost-efficient ISO-accredited chemical etching service that bypasses the physical limitations of conventional machining.

​

Moving Beyond Traditional Limitations

 

For years, stamping and laser cutting have been the workhorses of medical manufacturing. While precise, these mechanical processes rely on force and heat, which can introduce "trauma" to the metal itself.

​

• Material Stress: Mechanical force can warp or weaken the internal structure of the metal.

• Burrs: Tiny, jagged protrusions often remain after cutting, requiring secondary cleaning or polishing.

• Repeatability: As physical tools wear down over time, the 100th part may not be identical to the 1st.

 

In a field where cleanliness and structural integrity are mandatory, these drawbacks can lead to increased costs and potential quality risks.

​

The Chemical Etching Advantage: Stress-Free Precision

 

Chemical etching (also known as photo etching) offers an elegant solution. Instead of "punching" or "burning" the metal, we use precisely controlled chemical etchants to selectively dissolve material from a sheet.

​

Why this matters for medical components:

​

• 100% Burr-Free: Parts emerge perfectly smooth, eliminating the risk of sharp edges that could compromise a device or injure a patient.

• Stress-Free: Because no heat or physical pressure is applied, the metal’s properties—such as its strength and flexibility—remain completely unchanged.

• Absolute Cleanliness: The process is inherently "clean," ensuring components meet the rigorous standards required for surgical and implantable use.

​

Economical, Fast, and Uncompromisingly Accurate

 

 

Modern medical engineering moves fast. Metching’s digital tooling process allows for rapid prototyping and seamless design modifications without the massive overhead of physical die sets.

​

• Design Freedom: Engineers can design intricate, complex geometries without the "cost penalties" usually associated with complexity.

• Micro-Scale Accuracy: We can achieve feature sizes as small as 0.1mm with an incredible accuracy of ±0.020mm.

• Reduced Lead Times: Digital setups mean we can move from a design file to a physical part in a fraction of the time required by traditional tool-and-die shops.

​

Versatility Across the Medical Spectrum

 

The adaptability of photo etching allows designers to work with an extensive range of materials tailored to specific medical applications:

​

• Surgical Instruments:  Ultra-hard Stainless Steel  >>>  Exceptional sharpness and durability.

• Implantable Devices:  Biocompatible  >>>  AlloysLong-term safety and corrosion resistance.

• Electronic Shields:  Copper or Nickel  >>>  High conductivity and EMI shielding for medical monitors.
