Embodiment

[0017] Example: such as Figure 1 to Figure 3 Described, a kind of manufacturing method of electronic product shell, comprises the following steps:

[0018] Step 1: Select the compound of PC and 20%-30% CF as conductive plastic particles, select the compound of PPS and GF as non-conductive plastic particles, bake the conductive plastic particles and non-conductive plastic particles, and the conductive plastic particles The baking temperature is 120 degrees, and the baking time is 4H. The baking temperature of non-conductive plastic particles is 80 degrees, and the baking time is 4H;

[0019] Step 2: The main body of the conductive plastic particles is formed in the first mold A. The injection molding conditions are: mold temperature 70°C ~ 95°C, barrel temperature 270°C ~ 315°C, injection pressure 130~150Mpa, injection time 3~4 seconds, cooling time 40 seconds, back pressure 13bar;

[0020] Step 3: Use the two-color injection molding motorized template to rotate the ...

Abstract

The invention discloses a manufacturing method of an electronic product shell. The manufacturing method comprises the following steps: (1) baking conductive plastic particles and non-conductive plastic particles; (2) forming a main body of the conductive plastic particles in a first die A; (3) rotating the main body formed in the step (2) for 180 degrees by utilizing a movable die plate of a double-colored plastic injection machine, and forming the non-conductive plastic particles for the second time in a second die B after closing; and (4) taking out a formed plastic piece, and then performing burr processing. According to the manufacturing method, the main body made of carbon fiber achieves the conducting effect. Compared with common plastic particle EMI (Electro-Magnetic Interference), the plastic particles after metal aftertreatment have the advantages that the manufacturing procedure is reduced, and the environmental pollution is reduced; the wire part is made of the non-conductive plastic particles, so that the shielding effect caused by integral conduction is eliminated, the integral effect of the shell is increased, post process treatment is facilitated and the product diversification is increased.

Description

technical field [0001] The invention relates to a method for manufacturing an electronic product casing. Background technique [0002] The thinning and lightening of notebooks makes carbon fiber gradually replace magnesium alloy and develop rapidly in the field of notebooks. Carbon fiber can realize the thinning and thinning of the notebook case while ensuring the strength of the notebook case; however, the corresponding position of the antenna part of the notebook needs to be made of ordinary plastic parts, and its function is to prevent the carbon fiber parts from shielding the antenna signal. Traditional carbon fiber adopts hot pressing, in-mold injection molding and other processes, and the follow-up treatment is mainly painting, which is relatively simple. Contents of the invention [0003] The purpose of the present invention is to provide a method for manufacturing the casing of an electronic product. The main body of carbon fiber solves the need for electrical con...
