Casting and Molding
Mud plaster is poured into the use mold. Since plaster molds absorb water, the surface of the mold becomes thicker with clay as time passes after casting. When the required thickness is achieved, the mold is drained and excess plaster is poured out, and when it has hardened to the touch, it is removed from the mold.
If a shape cannot be formed in a single mold, parts cast in multiple molds are glued together.
鋳込み成形
使用型に泥漿を流し込みます。石膏でできた使用型は吸水性があるので、鋳込んでから時間が経過すると型の表面に陶土で厚みが付きます。必要な厚みになったところで排泥し余分な泥漿を流し出し、手で触れる程度に固まったら型からはずします。
一つの型で成形できない形は、複数の型で鋳込んだパーツを接着します。
being finished
Once the mold has dried and hardened to a certain degree, finishing is performed. Burrs are removed from mold joints, surfaces are smoothed, and details are finished and allowed to dry.
仕上げ
ある程度乾燥して固くなったら、仕上げを行います。型の継ぎ目のバリを取ったり、表面を滑らかにしたり、細部を仕上げ、乾燥させます。
