Abstract

PURPOSE: To reduce the drying time for mold production considerably without degrading the characteristics of the mold by drying the refractory coating layer consisting of a refractory slurry and refractory powder formed on the outside circumference of an investment casting pattern in an evacuated state.
CONSTITUTION: A refractory slurry consisting of a binder and a filler is coated on the circumference of an investment casting pattern formed to a prescribed shape, thence stucco is stuck, after which it is dried under evacuation to set the slurry, whereby the coating layer consisting of the slurry and the stucco is formed. The process of slurry coating, sticking and drying is repeated suitable times, whereby the coating layer of desired thickness is formed. Next, this pattern is eluted and is calcined, whereby the mold is formed.
