Problems solved by technology

Although the sandblasting method can increase the contact area between the plastic part and the metal part to improve the connection strength, the process of the sandblasting method is complicated, and the size of the micropores formed is uneven, which makes the connection strength between the metal part and the plastic part weak
Although focused ion beam etching can form inverted cone-shaped small holes to improve the bonding strength, it must be produced in a vacuum environment, and the cost is high. At the same time, its low processing speed cannot meet the processing requirements of large areas, so it is not suitable for investment. Mass production use
The micropores formed by the traditional electrochemical etching method are straight holes, so the connection strength between the metal part and the resin part is still not good

Embodiment Construction

[0019] see figure 1 The metal-resin composite body 10 according to the first embodiment of the present invention includes a metal part 110 and a resin part 120 combined with the metal part 110 .

[0020] The material of the metal part 110 can be aluminum alloy, magnesium alloy, stainless steel, copper and copper alloy. The metal part 110 has a metal part surface 111 combined with a resin part 120 , and a plurality of micropores 112 are provided on the metal part surface 111 . The micropore 112 is substantially in a T-shaped structure, which includes a top 1121 and a bottom 1122 , and the bottom 1122 is located at an end of the top 1121 away from the end of the resin part 120 . The top 1121 communicates with the bottom 1122 , the aperture of the bottom 1122 is larger than the aperture of the top 1121 , and the bottom 1122 has rounded corners. In this embodiment, the top 1121 is positioned vertically relative to the metal member surface 111 . Preferably, the plurality of micr...

Abstract

A composite of metal and resin includes a metal piece and a resin piece combined with the metal piece. A surface of the metal piece defines a plurality of micropores including an upper portion and a lower portion, the upper portion is communicated with the lower portion, and an aperture of the lower portion is larger than an aperture of the upper portion. The lower portion includes an undercut portion. The resin piece is partially embedded into the lower portion and the upper portion of the micropores. A method of manufacturing the composite of metal and resin is also provided.

Description

technical field [0001] The invention relates to a composite body of metal and resin and a manufacturing method thereof. Background technique [0002] In practical applications, it is often necessary to connect resin and metal to form a composite. [0003] One of the existing resin and metal connection methods is to use adhesives for bonding, but the method of bonding with adhesives cannot produce a composite body of metal and resin with high connection strength. Another connection method is to make multiple micro-holes on the surface of the metal part, then put the metal part into the mold, and inject the metal and resin parts into one. [0004] Methods for making micropores on the surface of metal parts include sandblasting, focused ion beam etching, electrochemical etching, etc. Although the sandblasting method can increase the contact area between the plastic part and the metal part to improve the connection strength, the process of the sandblasting method is complicate...
