Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incorrect cutting tools leading to burrs or deformation.Utilize high-precision cutting methods and ensure proper tool maintenance to achieve clean edges and maintain material integrity.
Ignoring proper edge finishing after cutting.Always deburr and smooth all edges to prevent premature failure due to stress concentrations or leaks in sealed systems.

Common Applications

  • Diaphragm manufacturing for pressure sensors and regulators
  • Sealing components for high-temperature and high-pressure valves
  • Thermal expansion bellows and compensation elements

⚠️ Engineering Warnings

  • Exercise caution when handling thin metal sheets to avoid cuts.
  • Ensure compatibility with specific process media and operating temperatures.
