A mold (100) for producing foamed articles is described. The mold comprises an upper mold and a lower mold (102) releasingly engageable in a closed position to define a mold cavity (106) having a parting line about a periphery of the mold cavity. The parting line of the mold defines: (i) a first channel (108) along a first length of a periphery of the mold cavity, and (ii) a second channel (110) in communication with first channel, the second channel having a second length which is less than the first length. A method for producing a molded article use is also described. The subject mold and method are particularly well suited for the production of molded foam (e.g, polyurethane) articles. |
