Improve the physical and mechanical properties of rubber products. The selection of vulcanization pressure needs to consider the following factors:
1) the formula of the rubber;
2) the plasticity of the rubber;
3) the structural form of the mold (molding, injection, injection, etc.);
4) Type of vulcanizing equipment (flat vulcanizing machine, injection vulcanizing machine, injection vulcanizing machine, vacuum vulcanizing machine, etc.);

Structural characteristics of the product. General principles for the selection of vulcanization pressure:
1) For compounds with low hardness (below 50-Shore A or lower), the pressure should be selected small, and the hardness should be selected large;
2) Small selection of thin products, large selection of thick products;
3) The product structure is simple and the choice is small, the structure is complex and the choice is large;
4) The mechanical properties require high selection and large selection, and low selection and small selection;
5) The pressure can be lower when the vulcanization temperature is higher, and the pressure should be higher when the temperature is lower.
