Cavity layout: in the multi cavity mold design, layout arrangement and pouring system cavity is closely related to the. Arrangement of cavity should enable each cavity equal total pressure from their sufficient pressure required by the gating system, to ensure that the plastic melt and evenly with each cavity, the plastic part quality stable in each cavity. Multi cavity mold, cavity usually uses circular permutation, type H in the template alignment, linear arrangement and the composite order symmetric layout.
  The cavity layout determines the runner layout, considering the flow of the layout design, as far as possible to make the shunt connected with the cavity of the props have the same shape and the same length, ensure keep step with each cavity molding, plastic quality uniform and stable; the cavity layout and gate opening position to symmetry, in order to prevent mold under partial load and overflow phenomenon; as far as possible to make the cavities to be compact in size, reduce mold.
  It should be noted that, multi cavity mold parts the best molding the same size and precision plastic parts, different principle should not production with a multi cavity mould.
