Because sheet metal processing for medical devices involves the manufacture of products that affect human life, strict quality standards different from those required for regular industrial enclosures are required. This article provides a detailed explanation of the quality control points that medical device manufacturers should pay attention to in sheet metal processing, as well as specific criteria for selecting a reliable contractor.

Specialties and quality standards of medical equipment sheet metal processing

In precision sheet metal processing for medical devices, particular emphasis is placed on biocompatibility, sterilization resistance, and corrosion resistance during long-term use. As a representative standard, obtaining ISO 13485 (Medical Device Quality Management System) certification is a must.

Main quality management projects

• Material standard compatibility: Uses medical grade stainless steel such as SUS304 and SUS316L
• Surface roughness control: In many cases, a finish of Ra 0.8 μm or less is required
• Welding quality: Defect detection using pinhole inspection and X-ray inspection
• Cleanliness: Ideally, assembly should be done in a clean room of class 1000 or less.

Five points to consider when choosing a contractor

Cost optimization of medical equipment sheet metal

In the pharmaceutical equipment market, where price competition is fierce, optimizing sheet metal processing costs is also important. In our case, automating the welding process achieved a 15% cost reduction compared to conventional methods. Our flexible quotation system, which can accommodate high-mix, low-volume production, has been highly praised.

Latest trends in surface treatment technology

Advanced technologies that can improve the sterilization resistance of medical devices include:

• Removal of fine irregularities by electrolytic polishing
• PVD coating for improved wear resistance
• Application of antibacterial coatings (e.g., silver ion technology)
