ABSTRACT:
The invention is concerned with an injection mold for making a plastic impedance measurement module having a generally flat metal grid imbedded in the plastic thereof with a plurality of pairs of electrodes upstanding generally perpendicularly from said grid, one pair into each of a plurality of chambers, said electrodes being uncoated by said plastic. The mold comprises a first mold half having a first generally flat recessed portion defining top surface of a base of the module and a plurality of channels extending from the first portion into the first mold half defining the plurality of chambers and including a plurality of pairs of spaced apart slots extending from the base into the first mold half, one of the pairs of slots extending into each of the chambers for accepting and preventing coating of the electrodes. Also part of the mold is a second mold half having a second generally flat usually non-recessed portion for mating with the first recessed portion to form the injection mold, the second portion having support means extending therefrom towards the first portion for supporting the grid. Also a part of the mold are means for moving the first and second mold halves together and apart and means for injecting plastic between the mold halves when they are together.
