analysis of the factors affecting mold thermal balance in the high pressure die casting hpdc process
This article provides a comprehensive analysis of the thermal behavior of molds in the high-pressure die casting process and demonstrates how different stages of the production cycle—including molten metal injection, lubrication, air blowing, and the cooling system—affect mold temperature, thermal balance, and mold life. Through numerical analyses and real measurement data, the author explains the concept of a stable thermal regime and emphasizes that precise heat control not only ensures the final casting quality but also prevents thermal shock, mold cracking, and production defects. Proper cooling channel design and optimal process parameter adjustment are highlighted as two key factors for achieving maximum mold performance and improving production efficiency.
