Japanese Patent JP5970795
Kind Code:
B2
Abstract:
A method for producing a composition for injection molding which contains an inorganic powder composed of at least one of a metal material and a ceramic material and a binder containing a polyacetal-based resin and a glycidyl group-containing polymer. The method includes: cryogenically grinding a first resin containing the polyacetal-based resin as a main component; cryogenically grinding a second resin containing the glycidyl group-containing polymer as a main component; mixing a powder obtained by grinding the first resin, a powder obtained by grinding the second resin, and the inorganic powder, thereby obtaining a mixed powder; and kneading the mixed powder.
