AI Technical Summary

Technical Problem

The existing magnesium alloy die castings have uneven temperatures at the junction of thick and thin parts, which leads to shrinkage cavities and porosity in the heat-bonding zone, affecting product qualification rate and production efficiency. In addition, the cooling effect is poor and real-time monitoring cannot be achieved, resulting in frequent mold repairs.

Method used

The high-pressure cooling oil system, controlled by a PLC, circulates at high speed within the magnesium alloy die-casting mold through tiny cooling channels. Combined with real-time monitoring and control by temperature and flow sensors, it achieves uniform cooling.

Benefits of technology

It improves the cooling efficiency of die-casting molds, reduces shrinkage cavities and porosity, increases product qualification rate, and enables automated control and safety monitoring of molds, avoiding accidents such as thermal cracking or explosion.
