Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the polycarbonate screw, which can lead to thread stripping or material fracture.Refer to torque specifications for the specific application and material. Use a torque wrench if precision is required.
Using in applications exceeding the material's temperature or chemical resistance limits.Verify the operational environment against polycarbonate's known resistance properties before installation.

Common Applications

  • Chemical processing equipment
  • Marine and offshore installations
  • Electrical and electronic enclosures
  • Medical device assembly
