摘要： A sublimation pattern casting method capable of achieving the optimum discharge of generated gas, comprising the step of performing a casting while discharging the gas generated by the sublimation of the pattern to the outside of a mold through a discharge passage having a discharge gas suppressing means when a product is cast by filling molten metal into the mold formed by burying a synthetic resin foam body pattern in foundry sand to sublimate the pattern by the molten metal, wherein the permeability of the discharge passage is controlled based on the material and shape of the pattern and the type and temperature of the molten metal.

摘要： A binder composition for use in producing molds, which contains a binder obtained by the polycondensation of monomers mainly comprising furfuryl alcohol, urea and an aldehyde and wherein a difference (A-B) between the weight percentage (A) of the feed furfuryl alcohol and the weight percentage (B) of the unreacted furfuryl alcohol, both based on the binder, ranges from 5.0 to 60.0. The composition serves to accelerate the hardening of the binder without worsening the working environment.
