Questions about about ADC 12 during Die Casting

+++

Hi,

I am interested in knowing the answer for following queries related with aluminum ADC 12 material:- 1) How can I know which chemical composition in ADC 12 will contribute to higher % of reject in die casting? (Examples: soldering, shrinkage, cold flow, crack, porosity and bubble/ blister?) 2) Is there a web-site that I can access to check on the above? 3) I am having problem on bubble/ blister during aluminum die casting, I have been looking into various ways to solve it but fail. Can anyone help? 4) Will electroplating contribute in bubble/ blister? If yes, how?

Thanks and regards,

Hi, folks. This is really a metal finishing website rather than a pressure casting website. Your questions are welcome, but we may not have people with experience to answer them. You may wish to post on another website rather than waiting. Good luck!
