The processes commonly used in the production of silica gel products include molding and injection molding, in which molding is applicable to a wider range of product types and has advantages that other processes do not have, but it also has its own shortcomings..

Molded silica gel products are usually formed by high-temperature vulcanization after putting solid silica gel raw materials with vulcanizing agent into a high-temperature mold and applying pressure through the vulcanizing machine. The hardness of molded silica gel is usually 30 ° C-70 ° C. The raw materials match the color paste to bring out the color. The shape of the mold determines the shape of the molded silica gel products. The molded silica gel products are the most widely used in the silica gel industry at present. It is commonly used to make silicone industrial accessories, gifts, bracelets, watches, key bags, mobile phone cases, kitchenware, cushions, ice lattices, cake molds, etc.

1、 Advantages of silicone molding:

1. It can be made into any shape.

2. High precision, regular and beautiful commodity shape.

3. The color is bright and can be colored at will.

4. The equipment has the advantages of simple operation, low cost and quick effect.

5. The product is not easy to deform during molding and has good dimensional stability.

6. Large flat products can be pressed.

7. It can save raw materials.

8. Molding can recycle many plastics, especially silica gel.

2、 Disadvantages of silicone molding:

1. General machines can only be made with length and width of 500 * 500mm, and customized machines can be made with length and width of 650 * 650mm.

2. Many burrs will appear in the production process.

3. The mold cost is relatively high, and the development cycle is 7-25 working days.

4. Long production cycle.

5. It requires staff operation and large labor force.
