The production process of silicone rubber products is a delicate and complex process that involves multiple steps and technologies. Firstly, the selection of raw materials is crucial. Silicone rubber is a mixture of silicone and rubber raw materials, therefore, selecting high-quality silicone and rubber raw materials is crucial. These raw materials need to undergo strict screening and testing to ensure the quality and performance of the product. After determining the raw materials, the next step is the process of ingredients and mixing. According to the needs of different products, silicon raw materials and rubber raw materials will be mixed in a certain proportion. This process requires precise weighing and stirring to ensure even mixing.
Next is the production of the mold. Mold is a key tool for producing silicone rubber products, which determines the shape and size of the product. The production of molds requires the use of CAD software for design and the use of CNC machine tools for processing. After the completion of mold production, strict inspection and testing are required to ensure the accuracy and quality of the mold.
Then there is the injection molding process of silicone rubber. In this process, the prepared silicone rubber raw material is injected into the mold, and through the action of pressure and temperature, the silicone rubber is fully filled in the cavity of the mold, ultimately forming the required product. The injection molding process requires controlling the parameters of temperature and pressure to ensure the quality of the product.
After the injection molding is completed, the silicone rubber product needs to be demolded and repaired. The demolding process is the process of removing silicone rubber products from the mold, which requires careful operation to avoid product damage. After removal, the product needs to be trimmed to remove excess edges and burrs, making it smoother and more aesthetically pleasing.
Finally, the post-treatment of silicone rubber products. After injection molding and finishing, the product still needs to undergo some post-processing procedures, such as vulcanization and cleaning. Vulcanization is the process of heating silicone rubber products in a vulcanization furnace to enhance their physical and chemical properties. Cleaning is the process of cleaning a product to remove surface dust and impurities, making it cleaner and more hygienic.
In short, the production process of silicone rubber products is a comprehensive process that requires strict control of the quality and process parameters of each link. Only with precise operation and control at each step can high-quality silicone rubber products be produced. These products are widely used in fields such as automobiles, electronics, and healthcare, bringing convenience and comfort to people's lives.
