The shock absorbers made by BJY are mainly designed for absorbing the large energy generated during the instantaneous opening and closing of the moving parts of the PET rotary blowing machine. With large energy absorption capacity, long life, and low noise, our shock absorbers have won large popularity in keeping the normal running of machines and extending the life of molds. BJY possesses a professional simulation platform to demonstrate the performance of the shock absorber during a real crash situation. The resting result shows that, our shock absorbers have equivalent performance with those imported ones.
