In our daily lives, silicone products are everywhere, such as silicone pads, silicone gloves, silicone pacifiers. Do you know what process is used to make these silicone products?

Today we are here to reveal the answer for everyone:

1. Compression molding: This is the most common process, mainly completed by mold coordination, and the shape of the mold determines the shape of the silicone product. Molded silicone products are usually formed by placing solid silicone raw materials with added vulcanizing agents into high-temperature molds and applying pressure through a vulcanizing machine. The hardness of molded silicone is usually between 30 ° C and 70 ° C. This production process is relatively simple and suitable for all silicone products.

2. Injection: This process requires high quality and is a combination of liquid silicone and plastic. Its products exhibit good thermal stability, cold resistance, excellent electrical insulation performance, and do not produce toxic substances during combustion. Therefore, it has become an irreplaceable material in the production design of health products, automobiles, baby products, medical supplies, diving products, kitchen utensils, and seals.

3. Extrusion: Extrusion molding and extrusion of Guangdong silicone rubber products are usually formed using a silicone extruder. The shape of the extruded silicone is generally longer and can be freely cut into tubes. The extrusion process is relatively simple, mostly in the form of strips.

4. Rolling: Silicone rubber is kneaded and mixed with white carbon black, silicone oil, etc. to make a mixed rubber, which is then rolled out using a rolling machine. The rolling effect is related to factors such as the composition of the compound, rolling temperature, and speed ratio. Used for larger products such as silicon wafers, silicone rubber sheets, etc.

5. Pouring: Operation method of filling or pouring mold: Pouring mold or pouring mold is used for relatively smooth or simple products. Without mold lines, it can save manpower and time. That is, the product or model you want to replicate is surrounded by rubber or glass plates, and the silicone gel pumped out by vacuum is directly poured into the product. Belonging to solid-liquid combination, using products such as phone cases and luggage cases. These are some common production processes for silicone products, but there are other processes and methods to choose from in the actual production process. The specific process to be used depends on the product requirements and production conditions.
