Liquid silicone rubber manufacturers tell you what steps the liquid silicone rubber molding process needs to go through

In the manufacturing process of liquid injection molding, the main products are obvious. The traditional working process focuses on pressurized impact mixing, which consists of a mechanical mixing process that combines two components together.

The main steps involved in the liquid silicone rubber forming process:

1, silicone rubber sealing ring manufacturers introduce the uncured silicone in the container, divided into compounds A and B, it is connected to the pumping system. The barrel holds the base forming material, and barrel B contains the catalyst. A unit of measurement automatically releases two substances in a constant ratio of one to one, as well as any pigment additive.

2, injection molding program can be divided into: custom automatic injection molding machine and injection molding set each work to provide the corresponding lens size. Templates and pistons, adjust and close molds, have temperature, set pressure with customer specifications according to injection speed and cycle time.

3. After installation, the machine will heat the mold to the appropriate temperature and apply the appropriate clamping force. The mold closes the injector, pump and supply of the mating machine. Injection mechanism and push the material into the cavity.

4. A combination of heat and pressure is applied to the liquid silicone rubber to solidify the material until solidification. At the completion of the cycle, the mold is opened and part of the flicker can be automatically or deleted by a worker. The mold is then closed and the process is repeated.

5, silica gel sealing ring manufacturers introduce the liquid silicone rubber molding process: after taking out items from the mold, the post-molding process may include de flashing, post-curing, inspection and packaging.
