Background

The process of producing rubber articles is a relatively complex process that generally requires, for example, raw material preparation, mastication, compounding, cooling, cutting, vulcanization, trimming and inspection. The raw material preparation is to cut dozens of kilograms of raw rubber raw materials (including natural rubber and synthetic rubber) which are massive into small blocks, then carry out the collocation and addition of the raw rubber raw materials, the compounding agent and the rubber auxiliary agent according to the performance requirement of the final product, and enter the plastication procedure, wherein the plastication is usually carried out in an internal rubber mixer; the plasticated rubber material is softened, and the compounding agent and rubber assistant are mixed into raw rubber to form rubber mass. The mixing of various raw materials in the micelle is only very uneven preliminary fusion at the moment; the kneading is usually carried out on an open mill, and the kneading is carried out by sufficiently mixing the raw materials which are not uniformly mixed. The mixing process needs heating to fully soften the crude rubber, then repeatedly mixing materials for several times, and then discharging in a sheet form on an open mill to enter the next procedure. This sheet-like rubber material is generally called a sheet stock because it is still in a raw state without being cured (vulcanized). The film stock just removed from the mill has two characteristics, one is a higher viscosity and the other is a higher temperature. After raw materials of the rubber product are made into a film by an open mill, the rubber product can be put into a die to be cured into a final product only by carrying out intermediate procedures including cooling, anti-sticking treatment, slicing, strip cutting, grain cutting, trimming and the like according to different technical requirements of the final product.
