Abstract
A method for joining a member to a diecast article using an apparatus comprising dies, an injection sleeve communicating with a cavity of the dies and a plunger tip slidably arranged in the injection sleeve for filling the cavity of the dies with the molten metal previously poured in the injection sleeve. According to the invention, the plunger tip is formed with an insert aperture for receiving the member to be joined such that a portion of the member extending beyond an upper surface of the plunger tip is exposed in the molten metal when it is poured in the injection sleeve, thereby sufficiently transmitting the heat of the molten metal to the portion of the member to obtain a metallurgical bond at a boundary between the member and the diecast article.
