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

Example Embodiment

[0019] See figure 1 The metal-resin composite body 10 of 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 piece 110 may be aluminum alloy, magnesium alloy, stainless steel, copper, copper alloy, etc. The metal piece 110 has a metal piece surface 111 combined with the resin piece 120, and a plurality of micro holes 112 are provided on the metal piece surface 111. The micro-hole 112 is roughly T-shaped and includes a top portion 1121 and a bottom portion 1122. The bottom portion 1122 is located at an end of the top portion 1121 away from the resin member 120. The top 1121 and the bottom 1122 are intersected, the bottom 1122 has a larger aperture than the top 1121, and the bottom 1122 has rounded corners. In this embodiment, the top portion 1121 is perpendicular to the surface 111 of the metal piece. Preferably, the plurality of micropores 112 are circular micropores ar...

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...
