Abstract

PROBLEM TO BE SOLVED: To form many small holes as cast, when a casting is manufactured. SOLUTION: Many fine wires 2 coated with resin, paint, parting agent, and coating agent is preliminarily inserted into a lost foam pattern 1 made of a foamed resin worked to the form of a prescribed shape in a manner in which the fine wires are extended through the lost foam pattern, and the lost foam pattern is buried into a molding sand 4 and a molten metal 6 is poured, then many small pores are developed as cast.
