The concept of the injection mould without runner

The so-called non-runner solidification mold is in the injection molding, the molten material in the runner always keeps the hot flow state. During mold opening, only the solidified products need to be taken out, without producing runner agglomerates. Compared with the traditional injection mold, this is an advanced injection mold technology and a hot spot in the development of plastic injection molding technology. Its biggest feature is to improve the utilization rate of materials, reduce production costs and ensure the forming quality of parts.
The non-runner condensate injection mold of thermoplastic refers to the method of heat insulation or heating in the mold to keep the plastic melt in the flow channel from the nozzle of the injection molding machine to the gate of the mold cavity in the molten state and continuously inject into the mold cavity.
Thermosetting plastic adopts the injection mold with warm runner, that is, the molten material in the runner is kept within the set temperature through temperature control
