PURPOSE:To efficiently dewax an injection-molded body contg. a binder such as a thermoplastic substance without causing deformation, crazing or cracking. CONSTITUTION:An injection-molded body contg. a binder is immersed in a prescribed solvent and extraction is started. At the same time, other solvent different from the prescribed solvent in the velocity of dissolution of the binder is continuously or stepwise added to the prescribed solvent and the velocity of dissolution of the binder is controlled by varying the blending ratio between the solvents. |
