Causes of mold damage in fully automatic low pressure casting machines

Causes of mold damage in fully automatic low pressure casting machines： 1. Mold temperature: The mold must be preheated to a certain temperature before production. Otherwise, when high-temperature molten metal is filled, cooling will occur, causing the temperature gradient between the inner and outer layers of the mold to increase, forming thermal stress and causing the mold surface to crack or even crack. During the production process, the mold temperature continues to rise. When the mold...
