Silicone rubber is an elastomer material often used in automobile, medical treatment, consumer electronics, power and infant and child industries. Generally, manufacturers of silicone rubber products need to mix the silicone rubber base materials, additives and pigments in a certain proportion according to the requirements of color and functionality. For example, the obtained silicone rubber premixed materials are tested to be qualified after preparing samples, and then further put into extrusion or molding equipment to produce finished products, If it is unqualified, the addition proportion of each component of the premix shall be adjusted and retested. However, mixing before product production not only requires additional equipment and material preparation varieties, but also may interrupt automatic production. In addition, for consumer electronics applications in direct contact with the skin, such as headset sheath, smart wristband, mobile phone sheath, etc., there may also be contaminated links in the mixing process, resulting in the risk of skin sensitization to consumers. In recent years, with the continuous upgrading of automation, digitization and intelligence in the manufacturing industry, as well as the pursuit and attention to efficiency, quality, safety and environmental protection, more and more enterprises hope to save the mixing steps, so as to further improve the production efficiency and ensure the quality of products and the safety and reliability of sensitive applications.
