Web15 dec. 2024 · Molds with direct sprue gates have no runners; instead, the material flows from the nozzle tip through the sprue and directly into the mold cavity. Such mold designs are very simple, but it is not possible to control the material flow or pressure via additional runners and gates; the injection pressure is dependent on the machine itself. WebThe inlet flow from the nozzle is distributed among all runner branches during filling. The flow distribution is dynamically adjusted, depending on the resistance from each branch. For example, if the melt front of one branch reaches a thin section, the flow resistance increases so that the flow rate in that branch is dynamically reduced.
