Problems solved by technology

[0003] Usually, when other materials are injection molded on both sides of a metal sheet, the molten material needs to flow from one side of the sheet and poured to the other side of the sheet, and the flow path is long, especially when forming thin parts. Because the gap for the flow of molten material is narrower, the solidification speed of the plastic material is accelerated, which often leads to the failure of the molten plastic material to completely fill the molding cavity and form defective products
In addition, because the plastic material covered by the plastic composite structure is relatively thin and there is no joint between the metal sheet and the plastic layer, the bond between the metal sheet and the plastic layer is not strong enough, and the plastic layer is easy to fall off from the metal sheet

Embodiment 2

[0023] The plastic composite structure 20 in the second embodiment can also be formed by the above two methods.

[0024] Because there are several through holes 15 on the edge of the main body 11, the molten plastic will not only flow from one side of the side wall 14 through its edge to the other side of the side wall 14, but can reach through several through holes 15 through multiple channels. On the other side of the side wall 24 , the molten plastic will be quickly and evenly distributed on the body 11 , and the mold can be opened and taken out after cooling.

[0025] It can be understood that the main body of the plastic composite structure of the present invention can be made of hard non-metallic materials other than metal. The shape of the through hole can be a through hole of any shape, such as hexagonal, octagonal, etc., or a combination of through holes of various shapes. In addition to the horizontal setting in Embodiment 1, it can also be converted into a vertical...

Abstract

The invention relates a plastic composite structure, which comprises a body and an inhibitory coating for the side wall of the body; the side wall of the body is provided with a plurality of through holes and the inhibitory coating is penetrated through the through holes. The plastic composite structure is capable of ensuring the effect that the coating material is firmly bound to the body. The invention also provides a method for preparing the plastic composite structure.

Description

technical field [0001] The invention relates to a plastic composite structure and a manufacturing method thereof, in particular to a sheet-shaped plastic composite structure and a manufacturing method thereof. Background technique [0002] At present, some thin metal sheets often exist in small electronic products such as personal digital assistants and mobile phones. Therefore, it is necessary to wrap a layer of plastic material on the edge of the metal sheet to form a plastic composite structure, thereby improving its strength and preventing It scratches the human body. [0003] Usually, when other materials are injection molded on both sides of a metal sheet, the molten material needs to flow from one side of the sheet and poured to the other side of the sheet, and the flow path is long, especially when forming thin parts. Because the gap for the flow of the molten material is narrower, the solidification speed of the plastic material is accelerated, which often leads to...
