Pores and bubbles: Problem description: Magnesium alloy easily absorbs gas in the liquid state, causing pores or bubbles on the surface of the casting, affecting product quality. solution: Reduce gas trapping and bubble generation through improved gating system design. Optimize the pouring process parameters, control metal temperature and pressure, and reduce gas inclusions. Use appropriate degassing treatment methods, such as vacuum degassing or gas dissolving agent treatment, to reduce the formation of pores. Structural distortion and deformation: Problem description: Magnesium alloy has high thermal conductivity and shrinkage rate, which can easily cause structural distortion and deformation of castings during the cooling process. solution: By optimizing mold design and process parameters, the cooling rate and temperature distribution are controlled to reduce the thermal stress of castings. Use an appropriate mold cooling system and cooling medium to balance the cooling rate and avoid deformation of the casting caused by too fast or uneven cooling. Use subsequent heat treatment processes, such as heat treatment or aging treatment, to reduce the internal stress of the casting and improve the dimensional stability. Hot cracking and cold cracking: Problem description: Magnesium alloys may produce hot cracks or cold cracks during the casting and cooling process, which affects the strength and durability of the product. solution: By controlling the temperature and cooling rate of the metal, we can avoid excessive or uneven shrinkage of castings during the cooling process and reduce the occurrence of hot cracks. Use appropriate mold preheating and preheating control to reduce the temperature gradient between the mold and the casting to prevent the occurrence of cold cracks. Optimize metal alloy composition and smelting process, reduce inclusions and impurities, and improve the crystallinity and crack resistance of castings. Surface quality issues: Problem description: Quality problems such as oxidation, pores, and blisters may occur on the surface of magnesium alloy castings, affecting the appearance and performance. solution: Use appropriate mold coatings and coating agents to improve the surface quality and lubricity of the mold and reduce the occurrence of oxidation and blisters. Optimize the pouring system and pouring process to reduce metal oxidation and bubble generation and improve the surface quality of castings. Strengthen mold maintenance and cleaning, check and replace molds regularly, and keep the mold surface smooth and clean. The above are some common problems and possible solutions during the magnesium alloy die-casting process. Companies need to take corresponding measures according to specific circumstances during the production process to improve product quality and production efficiency.
