This paper describes a new melt drag process for producing magnesium alloy strip with boss. This magnesium alloy part is made by model melt drag process. Model melt drag process replace solidification roll with flat substrate. The substrate has circular cylinder cavity and oval cavity. Molten magnesium alloy AZ31 feed into this cavity and form boss. The diameters of cylindrical geometry are φ5, 7.5 and 10mm. The measurement of oval cavity is width 5mm, length 30mm, depth 3mm. It was possible in the achievement of the filling of shape by keeping the melt temperature high, and the contact time between molten metal and substrate long. As result of microstructure observation, the cast defect such as shrinkage cavity did not exist, and fine and uniformly grain size (50〜70μm) confirmed.
