Research overview:
Precious metal ornament products are typical of high-mix low-volume production products. Recently, high-quality and thinner products are demanded. Lost-wax process is suitable for this type of products and most related companies in Yamanashi Prefecture use this process. The defective rate, however, is high because wax and base metals can easily deform and because many kinds of metal are used. Wax mold that will not easily generate misrun, blow and crack is produced to study defect causes and to find optimum casting conditions.
