Problems solved by technology

The notebook computer casing made by this method has the following disadvantages: ordinary engineering plastics are used, which is insufficient in rigidity and poor in pressure resistance, especially in the case where the antenna is assembled, the strength is not enough, it is easy to be broken apart and cause defects, and it can only play a decorative role; The thermal expansion coefficient of ordinary engineering plastics is quite different from that of metal parts, and the plastic shell is easy to deform

Abstract

The invention provides a notebook computer enclosure. The enclosure comprises a metal enclosure and a plastic frame and is characterized in that the plastic frame is provided with at least one concave notch, and the plastic frame is formed by injection molding of high-rigidity engineering plastics and is combined at the periphery of the inner surface of the metal enclosure through in-mold injection molding. Compared with the prior art, the notebook computer enclosure has the following beneficial effects that the plastic frame is formed by injection molding of the high-rigidity engineering plastics and is combined with the metal enclosure; the high-rigidity engineering plastics have high rigidity, so that the notebook computer enclosure has metallic appearance, is not easy to damage and is especially not easy to break off at the enclosure part of an assembling antenna, thus not affecting a communication effect of wireless operation; and contraction effects of the plastic frame in the molding process are reduced due to the arrangement of the at least one concave notch on the plastic frame. The invention also provides a manufacturing method of the notebook computer enclosure.

Description

【Technical field】 [0001] The invention relates to a notebook computer casing and a manufacturing method thereof, in particular to a notebook computer casing in which high-rigidity engineering plastics and metal are combined through in-mold injection molding and a manufacturing method thereof. 【Background technique】 [0002] Under people's increasing pursuit of high quality of life, people's pursuit of household products is also paying more and more attention to their shape and appearance decoration effect. The appearance of 3C products is becoming more and more colorful. In line with the thin and light metal wind became popular. At present, the development trend of 3C products is to develop in the direction of thinning. Among them, metal stamping parts are more and more widely used, but metal stamping parts have defects such as inability to have a long hook structure. High-rigidity plastic fiber-filled materials are more and more widely used in notebook computers. Rapid H...
