A local aluminum foundry was experiencing issues with impurities in their castings and needed a quick, complete package solution to improve the quality of their finished product. C.H. Reed was able to determine that the impurities were being caused by the presence of hydrogen in the molten aluminum creating these gas pockets, which when solidified, become weak spots. The quickest and most effective way to get the hydrogen out of the process is with an on-site nitrogen generator. This introduces nitrogen into the molten aluminum and draws the hydrogen into bubbles that are released at the surface. Overall, we were able to help this foundry eliminate the impurities with a plug and play system that increases worker safety, is cost effective, offers a continuous supply of nitrogen, and improves the effectiveness with no gas wasted.
