Problems solved by technology

[0003] However, after the plastic is injected into the through hole and plastically formed, it will not be tightly combined with the metal shell due to plastic deformation, and defects such as cracks and uneven surfaces will appear.

Embodiment Construction

[0033] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] The embodiment of the present invention discloses a method of injection molding on the metal casing. The manufacturing method can reduce the plastic deformation of the plastic 5 after injection molding, and further increase the bonding ability of the plastic 5 and the metal casing 1 . The manufacturing method includes the following steps:

[0035] S1: if figure 1 and figure 2 As shown, a sinker 2 is formed on the outer surface of the metal shell 1 and the inner surface thereof, and a reserved thin wall 3 is formed between the bottom of the sinker 2 and the inner surface.

[0036] Since the metal casing 1 has a signal shielding effect on the antenna of the notebook computer, it is necessary to arrange a plastic 5 at the ...

Abstract

The invention discloses a method for injection molding on a metal shell, a manufacturing method for the metal shell of a notebook computer and the metal shell. The method for injection molding on the metal shell includes the steps that S1, machining from the outer surface to the inner surface of the metal shell is carried out to form a sinking groove, and a reserved thin wall is formed between the bottom of the sinking groove and the inner surface; S2, plastic cement is injected into the sinking groove to enable the plastic cement to be subject to plastic molding; and S3, the reserved thin wall is broken and removed. As the reserved thin wall has the effects of keeping the plastic cement so as to prevent deformation of the plastic cement, the plastic cement injected into the sinking groove is tightly bonded with the metal shell, the plastic deformation of the plastic cement is smaller, and the surface quality is better.

Description

technical field [0001] The invention relates to the field of computer manufacturing, in particular to a method for injection molding on a metal casing, a method for manufacturing the metal casing of a notebook computer and the metal casing. Background technique [0002] With the rapid development of electronic products and the demand for thinner and lighter electronic products, metal thin-walled parts are also developing in more and more directions. However, the electromagnetic shielding characteristics of metal parts have a great impact on the antenna of the product, seriously affecting the product. Signal sending and receiving, for example, if the casing of a laptop computer is made of metal, the ability of the antenna inside to send and receive signals will be weakened. In order to avoid the shielding effect of the metal shell on the antenna, it is necessary to make some improvements to the metal shell during the production process, that is, after the metal shell is injec...
