Liquid Silicone Injection Process

The liquid silicone injection process is an energy-saving and environmentally friendly silicone production process. It injects liquid silicone into the mold through a loading system, and then solidifies the silicone products through the combined action of heat, pressure and time. Compared with the molding process, its use of the injection process can produce more complex silicone products. The liquid silicone raw material used has low volatility, low molding temperature, and is more environmentally friendly and energy-saving. It is widely used in the medical and food industries.

Its main production process is: A+B rubber + color paste – feeding system injection of rubber – mold forming – inspection – next process

Advantages of the injection process
1. Silicone products with complex shapes can be produced with high production efficiency and can be produced automatically.
2. Better control the material injection weight and position, making the rubber material more evenly distributed and with higher dimensional accuracy.
3. The entire molding process is carried out in the barrel and screw. The rubber material is not easily contaminated, and the production yield is higher. It is more advantageous for colored products.
4. The production is low-temperature molding, which is relatively energy-saving and conforms to the concept of “green production”.
5. The raw materials are environmentally friendly, especially suitable for medical, food and other industries.
