In a method of making molded articles, such as particleboard from mixtures of wood chips or like particles, bonding agents and reaction accelerators, initially the particles are divided into two portions A and B. Portion A is wetted with bonding agents and portion B is wetted with reaction accelerators. The two portions A and B are maintained separate until they are mixed loosely layered together and introduced randomly into a mold forming a mat. Within the mold, the mat formed by the particles of portions A and B are pressed together and the pressing action triggers the reaction hardening. Prior to the pressing step, the mutual contact of the particles in the mat of portions A and B causes only limited hardening bridges.
