Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive torque, leading to stripping or cracking the polycarbonate.Apply torque conservatively, using a torque wrench if precise control is needed, and consult material specifications for recommended torque limits.
Using metal tools that can scratch or damage the polycarbonate surface.Utilize tools with appropriate coatings or plastic-tipped tools where direct contact with the fastener head is unavoidable.

Common Applications

  • Electronic enclosures and assemblies
  • Medical device manufacturing
  • Food processing equipment
  • Corrosive environments

⚠️ Engineering Warnings

  • Not suitable for high-temperature applications above the polycarbonate's continuous operating temperature limit.
  • Avoid prolonged exposure to aggressive solvents that may degrade polycarbonate.
