Abstract

A method for manufacturing a thixomolding material for thixomolding includes a drying step of heating a mixture containing a first powder that contains Mg as a main component, a second powder, a binder, and an organic solvent to dry the organic solvent contained in the mixture, and a stirring step of stirring the mixture heated in the drying step.

Claims (12)

1. A method for manufacturing a thixomolding material comprising:

a drying step of heating a mixture containing a first powder that contains Mg as a main component, a second powder that contains C as a main component, a binder, and an organic solvent to dry the organic solvent contained in the mixture so that the second powder covers the first powder with the second powder being attached to a surface of the first powder;

a stirring step of stirring the mixture heated in the drying step; and

a debindering step of debindering at least a part of the binder contained in the mixture so that an attachment amount of the second powder attached to the first powder is 9.2% or greater and 27.9% or less after removal of the part of the binder, the attachment amount being a ratio of a mass of the second powder attached to the first powder with respect to a mass of the first powder.

2. The method for manufacturing the thixomolding material according to claim 1 , wherein

the drying step and the stirring step are alternately performed a plurality of times.

3. The method for manufacturing the thixomolding material according to claim 1 , wherein

the drying step and the stirring step are performed at the same time.

4. The method for manufacturing the thixomolding material according to claim 1 , wherein

in the debindering step, the mixture is heated at a temperature of 250° C. or higher.

5. The method for manufacturing the thixomolding material according to claim 4 , wherein

in the debindering step, the mixture is heated at a temperature of 450° C. or lower.
