Beschreibung
Zusammenfassung:	PURPOSE: An injection molding method is provided to uniformly keep the physical properties of injection molded products by using an optimized ram-speed profile calculated by numerical analysis. CONSTITUTION: An injection molding method using an optimized ram-speed profile comprises the steps of: measuring the physical properties and viscosity of injection molding materials; calculating the optimized ram-speed profile by using the measured physical properties and viscosity of the injection molding materials; and applying the calculated optimized ram-speed profile to an injection molding process.
