Abstract

The laminated molds are manufactured by diffusion bonding of laminated sheet metal sheets cut by laser. Since channels for water can be circulated arbitrarily in the mold, the temperature control of the mold can be easily performed, shortening the cycle time and improving the forming accuracy. Thus the laminated molds are often used for injection molding. In this application, the diffusion bonding strength is important to endure the pressure of injection. Although the tensile strength test is normally used as a method to evaluate the bonding strength, test pieces should be cut out from the mold. Thus this paper proposes a non–destructive method to evaluate the bonding strength of the laminated molds using ultrasonic waves.
