Die casting production process will appear the quality problem of the different factors, in addition to the die casting equipment, equipment performance and quality to cause system instability factors, there are some accessories and equipment (such as pressure cylinders, punch, cooling pipe, etc.) process parameter accuracy, and the quality of the material can produce certain influence on die casting production (such as release agent, lubricating bead, the cooling water), The purity of liquid aluminum will also bring the corresponding unstable factors to die casting (such as waste, gate, overflow block, the proportion of cleaning material), and smelting process control. Although...
