The process is performed with an open nozzle. The material is injected, and the mouled part is filled completely. The second cavity is closed. A hydraulic slide gate opens the secondary cavity. The gas injection begins concurrently and the excess material is forced into the secondary. The gas holding sequence runs completely through. The recovery of the gas follows after the gas holding phase. The screw can simultaneously begin dosing again. The process is shown in Figure 10.23
