There are many kinds of rubber products, such as rubber sealing ring, rubber gasket, oil seal, rubber strip and so on.But their production process is basically the same, mainly including: raw material preparation → mixing → mixing → cutting → molding vulcanization → burr treatment → maintenance → packaging and shipping.

 

1. Preparation of raw materials

The main materials of rubber products are raw rubber and compound agent.Among them, raw rubber is the basic material, and the compound is an auxiliary material added in order to improve some properties of rubber products.During the preparation of raw materials, ingredients must be weighed accurately according to the recipe.

2. Mixer

In order to make the raw glue and the complex can be mixed evenly with each other, it is necessary to process some materials, this process is called inner mixing.

3. Mixing

In order to adapt to a variety of different conditions of use, obtain a variety of different properties, but also to improve the performance of rubber products and reduce the cost, it is necessary to add different complexes in the raw rubber.Mixing is a process in which the raw rubber after internal mixing is mixed with the complex agent and placed in the mixing machine. Through mechanical mixing, the complex agent is completely and evenly dispersed in the raw rubber.

4. Blanking

According to the weight and size of the product, cut into strips of different size and weight of raw materials, to molding vulcanization.

5. Molding

Cut the strips of raw materials, into the mold, through the high temperature of the molding machine, the raw materials dissolved in the mold forming.

6. Rough edge processing

Separate burrs from the product. This includes manual burrs and mechanical burrs.

7. Product inspection 

Through artificial, the appearance of the poor product selection, poor appearance mainly includes rough edges, dirty mold, immature, lack of material, blisters, etc..

8. Packaging and shipping

Shipment according to different size, packaging different quantity of shipment.
