Liquid Interface Diffusion Bonding Applications for Joining Plastic Injection Die Molds with Conformal Cooling, Hot Runners, and other Venting Attributes

摘要

The following paper discusses using liquid interface diffusion bonding, as conducted within a vacuum hot press furnace, as the preferred method of joining layered die mold blanks that may contain conformal cooling, venting, and other "hot runner" passages. Discussions about process methods and distinctions when using a vacuum hot press furnace, particularly compared to conventional vacuum furnace brazing, during the mold joining operations are made.
