The thickness of the aluminum die-casting mold wall directly affects the quality of the die-casting
Publish Time: 2024-08-05
The surface layer of the die-casting has fine grains and a dense structure due to rapid cooling, and its existence makes the die-casting stronger. If the wall is thick, the grains in the middle layer of the die-casting wall are coarse, which is prone to shrinkage holes, shrinkage and other defects. The mechanical properties of the die-casting will also decrease with the increase of wall thickness, and the amount of materials and the weight of the die-casting will also increase. In order to facilitate the flow of molten metal and the molding of die-castings, and to prevent stress concentration and cracks between die-castings and die-casting molds, the connection between the walls of the die-castings generally adopts the fillets and corners recommended by domestic and foreign design standards to strengthen the sudden transition connection.
