Abstract

Process comprises compacting the material by application of opposing forces acting in a no. of longitudinal planes normal to a central longitudinal axis which, after compacting is completed constitutes the longitudinal axis of the elongate body. The process avoids variation in the volumetric load and matrix density of the particles.
