Abstract

A molding apparatus, using raw material substantially comprised of crumbed rubber tires, and producing end products of durability and structural integrity. Products such as fence posts and dimensioned pieces like dimension-lumber products, have a hardened, dense outer wall structure surrounding a comparatively less dense and relatively porous central core, with the attendent structure integrity advantages of tubular and hollow-walled products. Heat fused raw material is fed under pressure, as from a screw extruder mechanism, through selectively controlled input valves to mold bodies, with the mold bodies carried in a chilled environment to establish fluid flow paths and hardening sequences leading to the desired end product body structure.
