First of all, rubber molding, extrusion through the pressure is caused by the joint preparation of the elastomer can not be eliminated, from the molding of the mold, often produces unstable shrinkage (since different types of plastic rubber shrink is different), it is necessary after some time, Moderately stable. So when a rubber product is designed, regardless of the formula or mold, and need to be cautious, if not, then the product size tends to be unstable, resulting in poor quality products.

Second, rubber is a hot-melt thermoset elastomer, and the plastic is cold-cured. Due to the different main bodies, rubber vulcanized species have a considerable temperature range of molding and curing, even due to changes in climate, indoor temperature and humidity. Therefore, the production conditions of rubber products need to be adjusted accordingly. If not, the difference in product quality can be made.

Third, the rubber miscellaneous products are manufactured as rubber compounds made of raw materials. The mixing time depends on the rubber products, the design features required for the formulation, and the required product hardness. Product rubber vulcanization molding machine molding. Finally, after the burr treatment, the surface of the product is smooth and burr-free.

Fourth, the rubber aging test microspectral analysis is the aging test class refers to the comprehensive impact of structural and structural changes caused by internal and external factors during the aging, storage and use of rubber and rubber products, losing the use value, so the phenomenon . It is characterized by cracking, sticking, hardening, softening, chalking, discoloration, mold, and so on.
