Abstract: The present invention is directed to a process for making combustible foam celluloid munition parts having high aspect ratios, different densities or having an insert embedded into the foam celluloid munition part. The process for making such foam celluloid munition part requires pre-soaking dry particles of celluloid, placing the celluloid particles into a munition part mold, exposing the celluloid particles to high heat and pressure until the celluloid particles expand and fuse into the shape of the mold. Varying the density or the size of the celluloid particles used in the process produces munition parts having different densities. In addition, the placement of inserts into the particles prior to exposure to high heat and pressure produces munition parts having inserts that are useful for identification and tracking of such parts.
