The invention discloses a continuous precision forming device and process for amorphous alloy or composite materials of the amorphous alloy and belongs to the technical field of the amorphous alloy. According to the process, the specific device is adopted, and a certain temperature interval in the amorphous alloy melt solidification procedure is used, so that pressure precision forming is carried out on the amorphous alloy; and besides, heating, cooling, solidification and forming in the forming procedure are coordinated organically, so that continuous forming of the amorphous alloy is achieved. According to the technology, the characteristics of a high-viscosity rheological behavior, a smooth free surface, a low solidification shrinkage rate and the like of a supercooling liquid area in the alloy melt solidification procedure are fully used, and final amorphous alloy components are high in dimensional precision, good in surface quality, internally compact and free of the defects such as shrinkage cavities and shrinkage porosity. According to the continuous precision forming device and process for the amorphous alloy or the composite materials of the amorphous alloy, the process flow is short, production efficiency is high, cost is reduced, and product quality is good.
