Title:
EVAPORATIVE PATTERN FOR CASTING, AND CAST ARTICLE
Document Type and Number:
WIPO Patent Application WO/2012/101824
Kind Code:
A1
Abstract:
Provided is an evaporative pattern which has high strength.
An evaporative pattern (102) is a pattern for evaporative casting. The evaporative pattern (102) is obtained by burying a reinforcing member (30), which is formed of a material that is not evaporated by the heat of a melt, in a joint (114) which is formed of a material that is evaporated by the heat of the melt. A typical evaporative material is polystyrene foam, and the polystyrene foam is low in strength. The strength of the evaporative pattern (102) is improved by burying a reinforcing member in the evaporative pattern (102) that is formed of polystyrene foam, said reinforcing member being formed of a material that has higher strength than the evaporative material.
