What are the molding methods of silicone products? Silicone products are widely used in various fields because of their excellent physical properties, chemical properties, etc. In the process of manufacturing silicone products, molding is a crucial step.
1. Injection molding
Injection molding is a more common method of molding silicone products. The method is to inject liquid silica gel into the heated silica gel material, and then form the desired shape of silica gel product in the mold through high temperature and high pressure processing. Compared with other forming methods, injection molding method has high accuracy, high material utilization rate, and can be automated production.
2. Calendering forming method
The calender forming method is to calender silica gel into a sheet shape, and then form a product by die-cutting. Its production process is simple, low cost, suitable for the production of some simple silica gel products, such as silica gel sheet and silica gel strip.
3. Molding method
The molding method is to press the silicone material into the mold, and use the high temperature and high pressure processing method to make the silicone material formed. The method is suitable for the production of medium-sized silicone products, such as silicone sealing rings, silicone pipes, etc.
4. Electrostatic spraying forming method
Electrostatic spraying molding method is to spray silicone evenly on the surface of the appliance and cure naturally in the air, and can be released after silicification to get the desired silicone products. The method has high production efficiency and is suitable for mass production of silica gel products.
