1. Basic process flow
With the development of modern industry, there are many kinds of rubber products, such as rubber sealing ring, silicone sealing ring, fluorine rubber sealing ring and so on. But its production process is basically the same.
The production process of raw rubber products mainly includes: raw material preparation → banburying → mixing → cutting → molding and vulcanization → burr treatment → maintenance → packaging and shipping.
2. Raw material preparation
The main materials of rubber products are raw rubber and compounding agent. Among them, raw rubber is the basic material, and the compounding agent is an auxiliary material added to improve some properties of rubber products. During the preparation of raw materials, ingredients must be accurately weighed according to the recipe.
3. Mixing
In order to make the raw rubber and the compounding agent mix evenly with each other, some materials need to be processed, and this process is called banburying.
4. Mixing
In order to adapt to various conditions of use, obtain various properties, and in order to improve the performance of rubber products and reduce costs, different compounding agents must be added to the raw rubber.
Mixing is a process in which the mixed raw rubber and compounding agent are mixed and placed in a rubber mixer, and the compounding agent is completely and uniformly dispersed in the raw rubber through mechanical mixing.
5. Cutting
According to the weight and size of the product, cut into strips of different sizes and weights, and wait for molding and vulcanization.
6. Forming and vulcanization
Put the cut strip raw materials into the mold, and melt the raw materials in the mold through the high temperature of the molding machine.
7. Burr processing
Separating the burrs from the product, including manual plucking and mechanical burring.
8. Overhaul
Through manual selection, the products with poor appearance are selected. The poor appearance mainly includes burrs, dirty molds, undercooking, lack of materials, and blistering.
9. Packing and shipping
According to different sizes, different quantities are packaged for shipment.
