Hi All,
We faced a problem with a Chinese foundry on a precision casting: They poured the same part from CD4MCuN with no problem before but now they have this sand inclusion problem with A216 WCB (as shown attached)! I am wondering if any body has experienced this kind of defect and know the root cause? This is the critical path for a big project so any recommendations would be much appreciated!
Thanks.
