ABSTRACT:
In an apparatus for encapsulating objects in molded plastic packages, an improved removable cavity plate assembly comprises upper and lower cavity plates which fit together in an interlocking manner to define molding cavities having integral surfaces formed within a single cavity plate on all sides of the cavity but one. The fourth side of each cavity is defined by a surface formed by the interlocking juncture between the two cavity plates. Plastic packages molded in the cavities thus are formed without a seam or parting line along the sides formed on the integral molding surfaces, the seam or parting line being formed only on the surface defined by the juncture of the two cavity plates.
