Abstract
There is an increasing demands of more efficient and economical ways of mold making according to the spreading trend of small quantity batch production system. Therefore, this study aims to examine the applicability of ultra high strength concrete, which has a compressive strength over 80MPa, as a mold material. The ultra high strength concrete has several advantages such as lower cost, lighter weight and convenience of shape making compared to the traditional mold materials. Although the strength of the ultra high strength concrete is lower than that of the tool steel, it was considered to be useful for small batch processes with relatively low pressure. Therefore, in this study, a prototype mold for reaction injection molding of polyurethane was developed using ultra high strength concrete and it was examined that the possibility and characteristics of concrete as a mold material.
