Valve gate systems offer injection molders the optimal performance when using hot runner molds, yet the vast majority of hot runner systems sold are thermally operated. Generally the reason for the selection of thermal gate vs valve gate operation is purely cost.
INCOE® now offers a solution that offers the advantage of predictable consistent gate opening found in valve gates at a price nearer to that of a comparable thermal gate system.
Control Gates can also achieve the cycle saving advantage over thermally operated systems and can be used to eliminate drool when using a vertical injection molding machine in the same way as a more expensive fully operated valve gate system.
When optimal gate performance or sequential operation is the outstanding criteria; a full Valve Gate system is still necessary. However, when the selection is mainly focused on the operation of predictable gate opening/closing the Control Gate offers our customers the opportunity of substantial savings.
