Runners and gates control the flow of the molten material through the mold and into the cavity to create your final plastic part.
Sprue: The main channel in which molten resin enters the mold. This channel is typically larger ensuring that enough material is able to enter the cavity to fill the cavity completely.
Runner System: The runner system must be designed and incorporated into a mold to ensure that a consistent flow of material fills the mold at the right pressure. The runner system connects the sprue to the gate.
Gates: at the opposite end of the sprue gates are applied to the runner controlling pressure and flow of molten material.
We utilize several gate options to ensure that your part can be filled as completley and consistently as possible.
