In the present study, the influence of injection conditions on the tensile strength of a plane plate made of AZ91D was examined. The plane plate having a thickness of 2.5mm was molded in a metal die by using a Thixomolding machine and a test piece was cut out from it. The gate velocity was varied between 2.6m/s and 9.9m/s. The molten metal temperature was changed from 848K to 893K. The effect of solution heat treatment was also examined. The tensile strength was increased with an increase in the molten metal temperature. The tensile strength was increased with an increase in the gate velocity especially in the high molten metal temperature condition. In the case that the test piece was given solution heat treatment, the yield stress was decreased and the elongation was increased.
