A large lightweight molded coffin comprises a large pulp molded outer shell lined with a reinforcing spacer material such as single faced Re-board&#xae;, a honeycomb structure or a molded spacer material conforming to and adhering to said shell and an inner shell made of molded pulp or a paper based material. A method for manufacturing such a lightweight coffin involves pressing slurried pulp between a first male mold half covered with elastomeric material and a second female mold half, to form the molded pulp shell, and gluing the reinforcing spacer material to the interior of said outer molded pulp shell and the inner shell.

Large lightweight coffin and method for its manufacture

Press for making large molded pulp objects, which has a raisable and lowerable male mold half, perforated for suction dewatering after dipping into a pulp slurry. The molding surface of said male mold half is coated with an elastomer to preserve even surface contact with the molded pulp object during compression and during thermal expansion or contraction of said mold halves. Advantageous embodiments include vacuum distribution troughs beneath the elastomer layer in the male mold half, multiple wire mesh layers on top of the perforated elastomer layer, and slight lateral adjustability of the otherwise stationary female mold half.
