Basic rubber process
1、Basic process flow
With the development of modern industry, there is a wide range of rubber products, products such as rubber O-rings, rubber seals, silicone O-rings, silicone seals, fluorine rubber O-rings, fluorine rubber seals, silicone rubber products and so on. But its production process is basically the same. Raw rubber as raw material products, its production process mainly includes: raw material preparation → dense refining → mixing → cutting material → molding vulcanization → burr treatment → overhaul → packaging shipments.
2、Raw material preparation
The main materials of rubber products are raw rubber and compound. Among them, the raw rubber is the basic material, and the cooperating agent is the auxiliary material added in order to improve certain properties of the rubber products. In the process of raw material preparation, the ingredients must be weighed accurately according to the formula.
3. Secret refining
In order to make the raw rubber and the cooperating agent can be mixed evenly with each other, it is necessary to process certain materials, and this process is called densification.
4、Mixing
In order to adapt to a variety of different conditions of use, to obtain a variety of different properties, but also in order to improve the performance of rubber products and reduce costs, it is necessary to add different compatibilizers in the raw rubber. Mixing is a process of mixing the raw rubber with the compounding agent after refining and putting it in the refining machine, so that the compounding agent can be completely and evenly dispersed in the raw rubber through mechanical mixing action.
5、Cutting material
According to the weight and size of the product, cut into strips of different sizes and weights of raw materials to be molded and vulcanized.
6、Molding vulcanization
The raw material, cut into strips, is put into a mold, and the raw material is melted and shaped in the mold by the high temperature of the molding machine.
7. Raw edge treatment
Separate the burrs from the product, which includes manual burr pulling and mechanical burring.
8. Overhaul
Through manual labor, the appearance of bad products to pick and choose out, the appearance of bad mainly includes burrs, package wind, mold dirty, not cooked, lack of material, blistering and so on.
9、Packaging for shipment
Packaged in different quantities for shipment according to different size dimensions.
