Problems solved by technology

[0003] However, as far as the method of increasing the thickness of injection molded products is concerned, it not only increases the cost of raw materials, but also goes against the trend of requiring thin products
[0004] In addition, the method of using a plastic resin reinforced with a filler such as glass fiber will not only increase the cost of raw materials, but also cause some problems in the coating process.
[0005] In addition, in the method of inserting a metal plate and injecting it, since there is a difference in thermal expansion coefficient between the plastic resin and the metal plate, there is a problem that the injection molded product is bent, and the plastic resin that can be used is limited.

Abstract

The invention relates to an injection molded article and a method of manufacturing the same, wherein the rigidity of the injection molded article can be ensured and the selection free degree of the plastic resin is improved.The injection molded article of the invention is characterized by comprising the base material for forming the appearance of the injection molded article and metal wire fabrics formed inside the base material.

Description

technical field [0001] The present invention relates to an injection-molded product and a manufacturing method thereof, and more particularly, to an injection-molded product and a manufacturing method thereof capable of ensuring the rigidity of the injection-molded product and improving the degree of freedom of selection of plastic resins. Background technique [0002] For electronic products, in order to protect internal components, injection molded products used as casings are required to have a certain degree of rigidity. Common methods for securing the rigidity of injection-molded products include increasing the rigidity by increasing the thickness of the injection-molded product, increasing the rigidity by using a plastic resin reinforced with a filler such as glass fiber, or increasing the rigidity by inserting a metal plate. Ways to increase stiffness. [0003] However, as far as the method of increasing the thickness of injection molded products is concerned, not on...
