Liquid silicone injection molding process is a high-precision and high-efficiency plastic processing method. It uses liquid silicone as the raw material and injects it into the mold through high-pressure injection in the injection molding machine. After solidification, the desired silicone product is obtained. This process has a wide range of applications in the manufacturing of electronic products, medical devices, automotive components, and other fields.
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.
The liquid silicone injection molding process has many advantages. Firstly, due to the excellent fluidity of liquid silicone, it can completely fill the small gaps in the mold, thus enabling the production of products with complex shapes and high precision. Secondly, liquid silicone does not produce volatile organic compounds during the curing process and does not cause environmental pollution, meeting environmental requirements. In addition, liquid silicone has good resistance to high and low temperatures, chemical corrosion, and electrical insulation properties, making it suitable for applications in various special environments. In addition, liquid silicone products have good flexibility and durability, which can meet the needs of users.
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.
