In the stringent global market metalcasters face today, the need for precision is grossly imperative. Although North American plants still lead global investment casting with 50 percent of the market share, competition from world sources has never been more acute, as they duel their end-products against manufacturers worldwide. Any faults or complications may cause a firm to lose its business. One such fault or complication investment casters can improve upon is the detection and reduction of inclusion defects in their components. An inclusion defect occurs when loose material, such as that of a chipped mold or wax that wasn't sufficiently burned out, is collected in the casting during the pouring process. These particles may enter a casting due to a number of reasons such as poor wax or mold processing or the use of burnout ovens that have cracked shells from previous castings.
