Description

technical field [0001] The invention relates to the field of material technology, and more specifically, the invention relates to a computer casing and a manufacturing method thereof. Background technique [0002] The casing of a computer or electronic calculator can protect the internal parts, so when manufacturing the casing, it should be considered that the casing needs to have a certain mechanical strength to exert compression and shock resistance. [0003] With the development of technology, the casing of electronic computers has been endowed with more and more functions, such as anti-radiation, anti-corrosion, anti-static and heat dissipation. The casings of existing electronic computers or electronic products are mostly plastic, and most of them are plastics obtained by pressing a single type or a small number of resins, such as the invention patents with application numbers 2014108564356 and 2015107746775. Although plastics obtained by pressing a single resin The pr...
