Troubleshooting gate vestige in molding
WebFeb 1, 2001 · From a technical point of view, valve gate technology enables the production of low-stress injection molding parts, which almost always meet the requirements of a very low vestige. As a result, the lower degree of stress when gating with valve gate systems becomes relevant. WebOnly observations of the formation of gate vestiges can be found in the literature, but the …

WebMay 21, 2024 · Edge Gates. Edge gates, which can include fan and tab-shaped gates, are the most common ways to gate a tool. An edge gate introduces material at the main parting line, or where the two halves of the mold meet, with a perpendicular runner. Because edge gates are easy to machine, they can be widened or modified to help material flow.
