Abstract

PURPOSE:To improve joining strength of a cast-in body and to reduce man-hour by forming cavity between foaming resin body and ceramic cylindrical body, set a casting flask, next filling molding material and pouring molten metal under negative pressure condition. CONSTITUTION:Plural pieces of projections 3 are formed on inner peripheral face of foaming resin body 1 and at inner part thereof, the ceramic cylindrical body 4 is inserted to set in the casting flask 6. Next, the molding material 11 containing no binder is filled into the cavity between the casting flask 6 and the resin body 1, and the cylindrical body 4. After sealing the casting flask 6 with a heat resistant air-tightening seat 12, it is made to negative pressure condition and the molten metal is poured from the sprue 2. When the molten metal cools and solidifies, compressive stress to the cylindrical body 4 is absorbed with deflection of the molten material 11 and the metal displaced at the projection 3 part safely fastens the cylindrical body 4. By this method, the joining strength of the cast-in body is improved and as the molten work is simplified, the man-hour for the work is reduced.
