Analysis of Failure Causes in Die Casting Processing

Thermal fatigue cracking damage failure: During die-casting production, the die-casting parts are repeatedly subjected to the action of cold and heat stimulation, causing deformation on the formed surface and its interior, which leads to repeated cyclic thermal stress and structural damage and loss of toughness. This leads to the appearance and continued propagation of microcracks. Once the crack expands, molten metal is squeezed in, and repeated mechanical stress accelerates the crack propagation.

Therefore, on the one hand, at the beginning of die casting, the die casting must be fully preheated. In addition, during the die-casting production process, the die-casting parts must be maintained within a certain working temperature range to avoid early cracking and failure. At the same time, it is necessary to ensure that there are no issues with internal factors before and during the production of die castings. In actual production, most die castings fail due to thermal fatigue cracking.
