The parting plane is the contact surface between the stationary and moving sides of the plastic injection mold.The primary purpose of the parting plane is to tightly seal the cavity of the injection mold and prevent melt leakage.This seal is maintained through the application of literally tons of force(hence the term “clamp tonnage”)that are applied normal to the parting plane.While the term “part...

The mold layout design assumes that the number of mold cavities and type of mold has been determined.To develop the mold layout, the mold opening direction and the location of the parting plane are first determined. Then, the length, width,and height of the core and cavity inserts are chosen. Afterwards,a mold base is selected and the inserts are placed in as simple and compact a layout as possibl...
