Causes and solutions of friction ablation in aluminum die casting

Visual inspection: The surface of the die-casting part has rough surfaces in some positions. The reasons are as follows:

1.Improper position, direction and shape of the inner runner caused by the die-casting mold (mold)

2.Insufficient cooling of molten metal scouring the vertical part at the inner runner caused by casting conditions The solutions and prevention methods are:

1) Improving the position and direction of the inner runner is not good when the inner runner is adjacent

2) Improve cooling conditions, especially to improve the initial position of molten metal scouring

3.Add paint to the ablated part

4.Adjust the temperature of the alloy liquid to cause no air pockets 5.Eliminate alloy oxides on molds
