Designing and Building Complex Three-Plate Tools

Experienced mold designers must know how to adapt to challenging geometrical dimensional specifications.  Employing a three-plate tool can be a solution when searching for an ideal gate location, or when multiple gate locations are necessary.  

A three-plate tool has an additional stripper plate acting as a buffer between the injecting plate containing the multiple gate locations, and the B plate housing the cavities to mold the parts.  With this precision design, the sprue is ejected in between the first and second plates, and parts eject in between the second and third plates.  This allows for the parts and runner to separate, and is easily adapted with any automated auxiliary equipment just like any other mold and ejection system.

A Three-plate tool design can provide a more consistent flow to cavities with multiple gates, without the need for a hot-runner tool.  In most cases a three-plate tool will be less expensive than a true hot-runner tool, but still provide the increased pressure to fill and pack critical dimensional areas with an even flow of material.  This is beneficial in areas containing thin walls or tight tolerances.
