concerns regarding the functionality of the die-casting machinesAn improper casting pressure and filling speed, an improper injection force and clamping force, an improper match between the size of the casting and the projected area that the die-casting machine is capable of, etc. Die-casting molds have suffered from poor design and quality control issues for a considerable amount of time. It is possible for there to be inaccuracies in the mold fit, the grinding, the accuracy of the machining, t...

According to the findings of the study, when the casting temperature is less than 1430 degrees Celsius during the casting process, residual porosity accounts for 74.3% of the total porosity in aluminum alloy die-casting, whereas when the casting temperature is greater than 1430 degrees Celsius, residual porosity accounts for 74.3% of the total porosity in aluminum alloy die-casting.  To be specific, the findings of the study indicate that when the die-casting temperature is less than 1430 degree...

The oxidized slag is primarily distributed on the casting's upper surface, particularly at the corners of the casting mold, where no air is allowed to pass through. In most cases, the fracture is grayish-white or yellow in color, aluminum die casting parts and it is discovered through X-ray fluoroscopy or mechanical processing. It can also be discovered during alkaline washing, pickling, and anodizing processes.     The following are the causes: 1. The furnace charge is not clean...
