ABSTRACT

This study investigated the efficiency of mass production for metal type with the wax casting method using yellow earth. (1) The matrix material: Paraffin was useful as the material. (2) The mould material: Yellow earth was useful as the filling material. As for the functional material, 2% paper fiber plus 18% activated carbon were useful. (3) The metal components, pouring quantity, and pouring method: Bronze was effective. A small quantity of approximately 600 grams was poured using conventional method. (4) The number of character strokes: The number of character strokes had almost no impact on the success rate of casting. (5) The pouring direction of metal fluid: The biggest factor for the success rate was the pouring direction, that is, putting the character face in the lateral direction and pouring metal fluid in a standing manner. (6) The main path caliber for metal fluid: The diameter size of 8.5mm was sufficient. (7) The temperature of a mould: The temperature of 600℃ was sufficient as the burning temperature for a mould. The success rate was not affected by the mould temperature when pouring metal fluid. (8) The characteristics of type strokes: All the distinctive characteristics in 「Jikji」 were observed here. (9) The mass casting success and contraction rate: The highest success rate was 68.0%, and the overall success rate was 21.0%. The contraction rate was 3.07%. Therefore, it is confirmed that the mass production of one hundred types is possible with a single mould.
