In the die-casting production process, the forming conditions of die-cast parts are extremely harsh, subjecting them to repeated mechanical abrasion, chemical erosion, and thermal fatigue.
1. Molten metal enters the mold cavity under high pressure and high speed, generating intense friction and impact on the mold cavity surface, causing erosion and wear.
2. During the pouring process, slag is inevitably introduced. This slag exerts complex chemical effects on the surface of the formed parts. Compounds of aluminum and iron, acting like wedges, accelerate the formation and development of cracks in the die-casting mold.
