Embodiment Construction

[0022] Please also see figure 1 and figure 2 , and with image 3 , is a perspective view of the manufacturing process of the present invention and a combined cross-sectional view. As shown in the figure, the present invention mainly comprises the following steps:

[0023] 1. Combining the positioning member 1 with one or more through holes and the metal substrate 2, in the first embodiment of the present invention, the positioning member 1 can be set to include a vertical portion 11 and a horizontal portion 12 Shape (can also be flat plate shape), one or more through holes 111 or gaps 112 are provided in the vertical part 11 to form an anti-dropping structure, and the horizontal part 12 is combined with the metal by laser or resistance welding. Substrate 2.

[0024] 2. After the positioning part 1 is combined with the metal base material 2, the plastic material 3 is coated on the positioning part 1 by injection, and formed into different predetermined shapes, such as a f...

Abstract

The invention relates to a method for combining plastic to a metal substrate. According to the method, a positioning piece with one or more than one anti-disinhibition structure is fixedly combined to the metal substrate, and the plastic is wrapped to the positioning piece in a wrapped ejection mode, so that the plastic passes through and is hooked to the anti-disinhibition structure of the positioning piece, and the plastic is formed to form different shapes. By the method, the metal substrate can be combined with the plastic, the formed plastic passes through and is hooked to a through hole of the positioning piece to achieve a restraining effect, and the plastic is combined with the metal substrate integrally, so that the plastic is firmer.

Description

technical field [0001] The invention relates to a method for combining plastic with a metal base material, especially a method for combining plastic with a metal base material, and combining the molded plastic material with the metal base material to make the plastic material stronger. method. Background technique [0002] According to; general electronic products such as mobile phones, etc., because the casing is made of metal, it is difficult to combine with other parts such as plastic materials or screws (such as fixing posts for locking screws, etc.). The material is fixed on the metal substrate with an adhesive. It's just that it is difficult to achieve tight fixation, so that the assembly often causes the plastic material to fall off, which affects the quality of the product. In view of this, the applicant, based on years of experience in this business, through continuous research and experimentation, developed a method of combining, so that the plastic material comb...
