The innovative application of liquid silicone in waterproof structural components of mobile phones has solved the problem of water ingress in mobile phones. Secondary injection molding methods such as metal+silicone, plastic+silicone, glass+silicone, etc. will become a new trend in mobile phone waterproofing.

Silicone products are a type of environmentally friendly, low-carbon, and green product processed and molded from silicone as raw material. The main processing techniques include injection molding, extrusion molding, and compression molding. Silicone has superior properties that cannot be replaced by other soft rubber materials, such as good elasticity and waterproof and moisture-proof properties, acid and alkali resistance to various chemical substances, no harmful substances, and not easily deformed.

Silicone products are often used in high demand areas that come into contact with the human body, such as baby pacifiers, human organs, medical supplies, etc., and have a very broad application prospect. At the same time, silicone is a non petroleum product that does not rely on increasingly scarce petroleum resources. Therefore, silicone products have become a substitute for similar rubber and plastic products, which is the trend. Among them, injection molding liquid silicone can produce all high-temperature rubber products with simple process flow, high product accuracy, and large output, which will become a new trend in the development of the next few years.

Advantages of dual color silicone injection molding waterproofing compared to traditional smartphone waterproofing:
1. The traditional waterproofing methods used for mobile phones, such as adhesive bonding and ultrasonic welding, require manual operation in the middle, and their assembly accuracy and stability cannot be guaranteed. Disassembly and assembly are prone to damage, and the waterproofing effect is poor.
2. The liquid silicone injection molding waterproof structure is simplified, the overall structure is compact, the assembly accuracy and repeatability are high, the waterproof effect is improved, and the waterproof level reaches 5 or above.
3. The bonding strength between liquid silicone injection molding and secondary molding of materials such as metal and plastic is high, and it can be disassembled and assembled multiple times. It is easy to replace and has stable waterproof performance.
