The main steps of liquid silicone injection molding process include mold design, liquid silicone ratio, injection molding, curing, and post-treatment. Firstly, design a suitable mold based on the shape and size of the required product, and consider the fluidity of liquid silicone to ensure that the silicone can fully fill the mold during the injection process. Then, according to the requirements of the product, mix the liquid silicone with additives in a certain proportion to ensure the performance and curing speed of the silicone. Next, inject the mixed liquid silicone into the injection molding machine and inject the silicone into the mold through high-pressure injection. During the injection process, attention should be paid to controlling the injection time and pressure to ensure that the silicone gel can fully fill the mold and will not produce bubbles and defects. After the injection is completed, place the mold under appropriate temperature and humidity conditions to allow the silicone gel to solidify within a certain period of time. Finally, post-treatment processes such as demolding, trimming, cleaning, and inspection are carried out on the cured silicone products to ensure product quality.
In summary, the liquid silicone injection molding process is an advanced plastic processing method that can produce high-precision and high-quality silicone products. With the development of technology and the growth of demand, the application of liquid silicone injection molding technology in various fields will become increasingly widespread.
