Abstract

This paper describes a new method of making molds for injection molding of plastics. In this method, since molds are made by laminating metal sheets cut by laser, both delivery time and cost can be reduced compared with conventional die making methods. Furthermore, since channels for cooling water can be circulated arbitrarily inside the mold, higher production rate and quality of products can be achieved. In this study, diffusion bonding was used to bond the sheets, and a mold with excellent forming efficiency and accuracy was manufactured.
