Molding Cycle Sequence:
As the rotor is raised, polymer near the center of the rotor is drawn up, while polymer on the The “rotor” (a cylindrical rotating member), is centrally positioned in the “stator” (a cup like

polymer begins to melt, the rotor is raised and lowered. This achieves a radial mixing of a “folding back” nature.
The CSI-183IM’s system used to achieve this uniform melt mixture resembles the LE-075,

cup may be extruded out later; the mold can remain in the heater cup to form a portion of the next shot.
