MOLD-TOOL SYSTEM INCLUDING MANIFOLD ASSEMBLY HAVING MELT CHANNEL HAVING MELT-CHANNEL GEOMETRY FOR FOCUSING MELT-CHANNEL STRESS

摘要

A mold-tool system, comprising: a manifold assembly defining a melt channel, the manifold assembly having: a relatively critical operational area; and a relatively less-critical operational area being spaced apart from the relatively critical operational area. The melt channel has a melt-channel geometry. The melt-channel geometry is configured to focus, in use, melt-channel stress: (i) away from the relatively critical operational area, and (ii) toward the relatively less-critical operational area.
