= RESIN SWITCHING ASSIST METHOD AND APPARATUS FOR MOLDING MACHINE =

'''Abstract''':
for each of different resins r, a zero shear viscosity no of each resin r is obtained by using a conversion function expression whose parameters are a melt flow rate (mfr) and a set temperature of a heating cylinder and is registered. also, a purge resin required amount wu corresponding to a viscosity difference �d between the zero shear viscosity �of of a former resin rf and the zero shear viscosity �os of a succeeding resin rs is registered. when resin switching is performed, the zero shear viscosity �of of the former resin rf and the zero shear viscosity �os of the succeeding resin rs are obtained by inputting the mfr of the former resin rf and the mfr of the succeeding resin rs to a molding machine controller, the viscosity difference �d between the zero shear viscosity �of of the former resin rf and the zero shear viscosity �os of the succeeding resin rs is obtained, an amount of a purge resin required for resin switching is obtained as a purge resin required amount wu, and at least the obtained purge resin required amount wu is displayed.
