ABSTRACT

This study investigated the specific processes and principles of metal type wax casting method using yellow soil. (1) Matrix material: Beeswax and injection wax were useful. (2) Mould material: Yellow soil was useful as the filling material. Activated carbon, paper fiber and graphite, among others, were useful as the functional material. The mixture proportion was 10~18% for activated carbon, 2% for paper fiber, and 20% for graphite. In particular, paper fiber played a critical role in preventing cracks in the mould, improving the success rate of casting, and maintaining the type quality. (3) Metal components, pouring quantity, and pouring method: Bronze was more effective than brass as the metal component. A small quantity of approximately 350 grams was poured using conventional method. (4) The number of character strokes: The fewer the number of character strokes, the higher the success rate was. (5) The pouring direction of metal fluid: The biggest factor for the success rate was the pouring method; that is, putting the character face in the lateral direction and pouring metal fluid in a standing mode. (6) The main path caliber for metal fluid: The size of 4.5×5.0mm was sufficient. (7) The temperature of mould: The degree of 600℃ was sufficient as the burning temperature for mould. The success rate was not affected by the mould temperature at the time of metal fluid pouring. (8) The casting success and contraction rate: The highest success rate was 80.0%, and the overall success rate was 16.94%. (9) The characteristics of type strokes: All the distinctive characteristics in Jikji were observed here. Therefore, it appears that the wax casting method adopted by this experiment was the replication of the method actually used to cast Jikji type.
