The liquid silicone rubber injection molding process is as follows: the two liquid silicone rubber raw materials A and B are accurately metered by the metering device and then transported to the mixing device; the two components are fully mixed in the mixer and then transported to the injection molding machine; The molding machine injects or sprays into the preheated multiple molds and distributes them evenly to each mold cavity; in the hot mold cavity, the silicone rubber material is heated and rapidly vulcanized to form the product; after the vulcanization molding, the mold is automatically opened and ejected; then the mold is closed and enter the next molding cycle. The entire molding cycle takes tens of seconds to several minutes, and the molding cycle varies according to the size of the product.

The entire injection molding system is divided into the following parts: the first unit is the metering and feeding unit, which directly measures the two components of the liquid silicone rubber into the system from the packaging barrel through the hydraulic pressure plate; the second unit is the mixing unit , the two components entering the system are fully mixed through the static mixer, and no air bubbles are introduced into the system; the third unit is the injection molding unit, and the mixed silicone rubber material is quantitatively injected into the mold through the injection unit, and uniformly Distributed to each cavity, then hot vulcanized. The whole process is fully automated, and manual control can be achieved after setting the parameters to improve production efficiency.
