MOLD RUNNER FOR PREVENTION OF IN-MOLD COATING FLOW

Title:

MOLD RUNNER FOR PREVENTION OF IN-MOLD COATING FLOW

Document Type and Number:

WIPO Patent Application WO2003084730

Kind Code:

B1

Abstract:

A mold runner for a runner or sprue type injection molding apparatus. The mold runner allows the passage of a substrate material from an injection source into a mold cavity and contains a containment shroud which utilizes the relative incompressibility of the substrate material in the containment shroud which prevents an in-mold coating, which is injected into the mold cavity in a subsequent step, from flowing into the injection substrate source thereby contaminating the same.
