5, the casting wall thickness has changed dramatically, the contraction is blocked6, leaving die time is too long, stress is great7, the top out of force uneven
3, aluminum silicon alloy: aluminum silicon copper alloy, containing zinc or copper content is too high; aluminum magnesium alloy contains too much magnesium4, mold, especially the core temperature is too low
That's why so many,1, alloy iron content is too high or silicon content is too low2, the content of harmful impurities in the alloy is too high, which reduces the plasticity of the alloy
