The manufacturing process and process of silicone products are very complicated. It is necessary to make molds before they can make products. Many customers are not very clear about its several processes, and the result is a series of problems.

Silicone product manufacturing process:
1. Extrusion molding process
The customization of silicone products is like the extrusion of toothpaste. The extrusion head is the cross-sectional shape of the product. It has a certain length. Under the action of force and temperature, the product from the machine head has been vulcanized. The products formed by this process are generally strip-shaped products, and the product cross section can be various. For example, rectangular strips, ring-shaped silicon tubes, etc.

2, epoxy process
The raw material of the silica gel is in the form of a liquid, and the raw material is placed inside the syringe, and the raw material is dripped onto the mold by pneumatic and manual operation, and heated and vulcanized. This process belongs to the manual process and requires a lot of labor. Therefore, the production capacity is not high. It has a feature that a product can be dropped in a variety of colors upon request. Therefore, this kind of craft is mostly for making crafts. For example, multi-color silicone bracelets, silicone phone cases with various color patterns.

In addition to understanding the manufacturing process of silicone products, pay attention to the following aspects when processing silicone products:
1. If the temperature is too high, cracks will occur around the parting surface, especially for workpieces with large thickness. This is caused by excessive internal stress caused by expansion during the vulcanization process. In this case, the temperature of the mold should be lowered. The temperature of the injection unit should be set at 80 to 100 degrees. If you produce a workpiece with a relatively long cure time or cycle time, this temperature will decrease a little.

2. Silicone products are customized to introduce silicone rubber of peroxide curing system. The curing time is equivalent to fluororubber or EPDM rubber. For platinum silica gel, the curing time can be shortened by 70%.
