Inside ICI Put the Atlas of Casting Defects to Work for You T


• • • •


he Publications Committee has released a new revision of the Atlas of Casting Defects. The new edition addresses all the potential causes of a casting defect broken down by wax, shell or foundry.


This release has a new tool, the “Defect Identifier,” which can assist in pinpointing a particular defect. The only defects which are not included in this Atlas are wax defects which should be caught and corrected in the wax department. The Publications Committee expects to complete the Atlas of Wax Defects in late June. The online version is FREE to ICI Members and is also available for purchase for intranet use. Visit the ICI’s website www.investmentcasting.org for more information.
