<p><P>PROBLEM TO BE SOLVED: To form an evenly adhesive surface by an adhesive groove path which is left in advance between wax patterns, to increase the yield of casting, and at the same time, to increase the smoothness on the surface of a cast article. <P>SOLUTION: A back section cavity is formed on a main body wax pattern, and a shoulder section is formed on the lip edge on the back surface of a face plate wax pattern. The main body wax pattern and the face plate wax pattern are assembled, and the adhesive groove path is formed between the back section cavity of the main body wax pattern and the shoulder section of the face plate wax pattern. By filling the adhesive groove path with an adhesive, the main body wax pattern and the face plate wax pattern are bonded, and a head wax pattern is formed. A ceramic shell is formed by coating the head wax pattern, and a ceramic shell is removed from the pattern by heating and melting. The casting of the head is manufactured by performing casting by utilizing the ceramic shell. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
