Abstract

PURPOSE: To enable forming of a product, having a thick wall section and a thin wall section at the same time, to be accomplished by maintaining a special relationship among speed of jetting resin into a plaster molds, jetting pressure and an air vent diameter so that the formation of resin can be done with precision and stability.
CONSTITUTION: A spool runner 4 and an air vent 5 are formed with wax in perpendicular direction to joiningsurface of flasks 2 and 3 in which a wax original is kept, and after pouring and solidifying plaster 6, the flasks are heated to remove the wax and form a plaster mold 7. By providing an inside pressure detecting sensor pin 9 in a jetting hole 8 of the spool runner 6, ultra-hard resin is press-jetted into the plaster mold at a jetting speed of 0.01W10sec and a jetting pressure of 30W1200kg/cm2. Waste fume is smoothly released (or exhausted) from the air vent 5, blockaded by solidification of the resin and contraction due to solidification of the filler main to be jetted is compensated for by applying holding pressure. Diameter of the runner 4 is to be 0.5W20ϕmm and that of the air vent 5 is to be 0.1W5ϕmm.
