When the rubber gasket is molded, the cohesive force of the elastic body cannot be eliminated after being pressed by high pressure, and it tends to produce extremely unstable shrinkage when it is molded out of the mold (the shrinkage rate of rubber varies depending on the type of rubber) , After a period of time, it can be gentle and stable. Therefore, at the beginning of the design of a rubber product, regardless of the formula or mold, it is necessary to carefully calculate the fit. If not, the product size is likely to be unstable, resulting in low product quality.

Rubber is a hot-melt thermosetting elastomer, while plastic is hot-melt and cold-solid. Due to the different types of sulfide, the temperature range of the molding and curing of rubber is quite different, and it may even be affected by climate changes and indoor temperature and humidity. Therefore, the production conditions of rubber products need to be adjusted appropriately at any time. If there is no production condition, the product quality may vary.
