The injection method of the liquid silicone injection molding machine is hydraulic. The key to a silicone injection molding machine is to better handle various types of liquid silicone raw materials and ensure the pressure during the injection process. Usually, separate material barrels are used for mixing mechanical equipment to properly handle materials with different viscosities and ratios. Pressure monitoring is provided during transportation to understand the specific conditions of pipes and mixers in a timely manner, making the injection process safer and more regulated. Accurate operation ensures the injection accuracy and feeding precision throughout the injection process.
Liquid silicone injection molding is used for battery case waterproof products in mobile phones. For example, using PC, TPU, and LSR silicone rubber, they can be combined through two-color injection molding LIM molding process.
The resulting waterproof battery case has the following characteristics:
1. Achieves functions of waterproof, dustproof, and shockproof for mobile phones.
2. The surface is free of marks and does not require surface treatments such as spray coating.
3. The waterproof rating can reach IP67.
The liquid silicone-sealed battery compartment is formed on the back of the battery casing. With the premise of meeting the requirements for multiple disassemblies, it has sufficient waterproof performance.
