Vibration lost foam casting technology


Vibration EPC technology is to apply a certain frequency and amplitude of vibration in the process of EPC, so that the casting solidifies under the action of vibration field. Because the metal solution is vibrated for a certain time during the solidification process of EPC, the vibration force causes the relative movement between the liquid phase and the solid phase, and the dendrite is broken and increased. The crystallizing core in the liquid phase makes the final solidification structure of the casting refined, the shrinkage is increased, and the mechanical properties are improved. The technology makes use of the ready-made compact shaking table in lost foam casting and the mechanical vibration produced by the vibrating motor to make the liquid metal nucleate under the dynamic excitation, so as to refine the structure. It is a simple, low-cost and environment-friendly method.
