Effect of bonding interface on injection molded plastic parts using laminated sheet mold

Abstract

This paper describes the manufacturing of die for injection molding by diffusion bonding of laminated metal sheets. Channels for circulating water were designed 2x2 mm in cross section and a distance of 2mm from the surface of the mold. The die was designed in such a way that the bonding line positioned on the surface of the die. The effect of bonding interfaces on the appearance of injection molded plastic parts (polypropylene and polycarbonate) was studied. The results were compared with a solid surface die.
