Optical Module is a very important active device in 5G communication equipment. It is composed of Optical devices, functional circuits and Optical interfaces. The main function is to complete the photoelectric electro-optical conversion of optical signal. It is mainly used for telecom transmission, data center and 5G base station. The module has three core parts, optical chip, laser and optical prism; These three components have harsh requirements on the heat dissipation coefficient and thermal expansion coefficient of the carrier material, which is called optical chip base.
Vacuum precision casting is the perfect combination of vacuum melting and precision casting technology, under the environment of vacuum smelting, casting molding material for casting, pure copper and low chromium copper alloy precision casting are mainly used in electrical fittings, aluminum bronze, tin bronze material is mainly used in machine tool parts, precision casting wear-resistant fittings, ship with the pump body and other fields.
