We offer over 300 textures. You can discuss all technical details with our experts and artist.During the filling process, the temperature of the liquid metal decreases and the temperature of the mold increases, and the heat exchange between the two is unstable. As the temperature of the liquid flow decreases, the viscosity increases, and the flow resistance also increases; in addition, the pressure head of the liquid flow increases or decreases during the filling process, and the flow rate and flow state of the liquid metal also change continuously, resulting in the liquid metal filling the mold. Unstable flow in the process.
