Abstract:
      The influence of vulcanization molding processes on the quality of secondary suspension laminated auxiliary spring with high compound amount and thick compound layer was studied，and the method for determining the vulcanization time of this product was explored.The results showed that the die-casting vulcanization molding method could fully meet the production requirements of these products，with stable product quality and high production qualification rate.According to the results of differential scanning calorimetry analysis，nuclear magnetic resonance crosslinking density analysis and stiffness anlysis，the vulcanization time of the product determined by the critical bubble point time of compound layer was appropriate，and the product had been fully vulcanized.
