Abstract

The invention discloses a method for enhancing rigidity and dimensional stability of an injection-molded element. The method comprises the following steps of: mixing engineering plastic raw materials, auxiliary materials and glass fibers according to a certain proportion, prilling, drying, and obtaining a alloy material; setting the temperature of a hot flow channel of an injection mold and heating the injection mold; and injecting the alloy material on the injection mold by an injection molding machine, thereby molding the injection-molded element. The invention further discloses a surface shell of a liquid crystal display television, which is manufactured by the method. According to the invention, the rigidity and the dimensional stability of the surface shell of the liquid crystal display television can be enhanced.

Description

technical field [0001] The invention relates to the technical field of liquid crystal televisions, in particular to a method for improving the rigidity and dimensional stability of injection molded parts and a liquid crystal television cover. Background technique [0002] At present, most LCD TV panels are made of engineering plastic materials, such as ABS (acrylonitrile-butadiene-styrene, acrylonitrile-butadiene-styrene copolymer) or PC (polycarbonate, polycarbonate). With the increasing size of LCD TVs, thinner walls and narrower frames, the rigidity and dimensional stability of these materials have become difficult to meet the requirements of thinner flat-panel TVs and narrower frames. Contents of the invention [0003] The main purpose of the present invention is to provide a method for improving the rigidity and dimensional stability of injection molded parts, aiming at effectively improving the rigidity and dimensional stability of the LCD TV panel. [0004] In orde...
