2008 - Casting A Perfect Defect

0.00

Wax pattern defects come in a wide variety and have many causes. When defective wax patterns are cast, the defects are often perfectly reproduced in metal and then are mistaken for casting defects. This paper will explore wax defects, what causes them and how they can be eliminated. Case studies will identify the defect in the metal castings, show how they were traced to the wax pattern and identify the root cause of the defect in the wax pattern. A popular wax injector is investigated to learn what can go wrong with it and how wax defects are influenced by equipment maintenance.
