ABSTRACT:
The invention relates to a method and apparatus for transforming the physical characteristics of a material such as for an end finished molded product and to the materials or products obtained thereby. The method and apparatus are characterized in that the temperature of the material is simultaneously varied with at least one other rheological variable such as hydrostatic pressure, shear stress, mechanical vibration (frequency or amplitude), dielectric vibration (frequency or amplitude) for dielectric materials and electromagnetic properties for metallic materials. The variation in temperature and the simultaneous variation in one or more other rheological variables are intimately connected by a relationship selected and specifically programmed to obtain a product having improved properties.
