Sealing Performance Testing

Sealing performance is an important index to evaluate the quality of the vehicle, which directly affects the safety and reliability of the vehicle. For example, vehicles are often affected by various adverse factors from the outside world while driving, such as dust, silt, rain, sandstorms, etc. If the sealing of the vehicle is not good, these external unfavorable factors will enter the interior of the vehicle and cause damage to the parts and interior of the vehicle. In addition, poor sealing performance of parts may cause oil leakage, gas leakage, water leakage and other problems. These problems will affect the safety of the vehicle and reduce the service life of the vehicle, so sealing testing is very important.

The sealing performance of the vehicle is evaluated from static test and dynamic test. Professional sealing performance testing can help automobile manufacturers find and solve potential sealing problems in time, optimize automobile manufacturing process, and improve the safety and reliability of automobiles.

STEMart provides comprehensive sealing performance testing services around static test and dynamic test to ensure vehicle safety and improve vehicle service life.

Test Items

1. Static test

• Water leakage test
  • The water leakage test evaluates whether there is water leakage in vehicle doors, hoods, trunk lids, etc.
• Gas leakage test
  • The gas leakage test evaluates whether there is gas leakage in the doors, windows, exhaust pipes and other parts of the vehicle.
• Noise test
  • Noise test evaluates the sealing performance of the vehicle to avoid noise generation.
• Optical test
  • Optical test evaluates the sealing performance of the vehicle by observing optical changes in the sealing parts of the vehicle.

2. Dynamic test

• Wheel hub sealing performance test
  • Evaluate the sealing performance of wheels and tires to avoid air leakage
• Axle sealing performance test
  • Evaluate the sealing performance between the axle and the tires to avoid oil leakage
• Glass sealing performance test
  • Evaluate the sealing performance of automobile glass to avoid air leakage and noise
