Problems solved by technology

Because the car is affected by the external environment throughout the year, the car sealing strip is often prone to deformation and aging due to high temperature, low temperature, strong light irradiation and harsh environment corrosion, which seriously affects the sealing performance of the sealing strip. The shock performance and service life will affect the safety of the car. It is not only a consumable item in the auto parts, but also an unstable factor affecting the safety of the car.
