1. A method for combining heterogeneous metal parts, comprising steps of:
a) disposing a first metal part in a mold cavity of a lower mold, the first metal part including a bottom portion that is located in the mold cavity and a vertical portion that extends upwardly from one end of the bottom portion and that cooperatively defines a recess area with the bottom portion, the first metal part further including an extension portion that extends laterally from a top end of the vertical portion over a top surface of the lower mold, a level of an upper surface of the extension portion of the first metal part being higher than a level of the top surface of the lower mold;
b) disposing a first upper mold on the upper surface of the extension portion of the first metal part, so as to expose the bottom portion and the vertical portion of the first metal part from the first upper mold;
c) after step a), providing a bonding adhesive on the bottom portion of the first metal part, the bonding adhesive having a top portion to be higher than the top surface of the lower mold; and
d) after steps a), b), and c), pressing a second metal part downwardly to force a lower surface of second metal part to press against the bonding adhesive, the second metal part being made of a material that is different from a material of the first metal part, wherein the second metal part partially exposes the bottom portion of the first metal part and forms a gap with the vertical portion of the first metal part, and wherein a second upper mold is disposed on an upper surface of the second metal part opposite to the lower surface of the second metal part and a lower surface of the second upper mold covers the gap so as to allow the bonding adhesive to spread laterally in the recess area of the first metal part when being pressed, and so as to allow the bonding adhesive to upwardly fill the gap and to reach the lower surface of the second upper mold when the lower surface of the second upper mold is brought into contact with the top end of the vertical portion.
