The present invention is directed to a modular die unit comprising a plurality of individually shaped plates wherein the shaped plates are stacked in face to face juxtaposition, and when placed into such a juxtaposition exhibit useful polymer forming attributes heretofore unattainable by prior art practices. Single die plates are formed such that the plates exhibit a finite geometric relationship, which in turn provides resistance to flexural deformation of the individually shaped die plates and conversely, improved resistance to variability of the modular die unit and enhanced and predictable formation characteristics of the polymer material formed therewith. Each of said single die plates within the stack forming the modular die unit exhibit an x-direction, a y-direction, and a z-direction, wherein any one of said single die plates exhibit in said x-direction and y-direction to have at least a 50% planar continuity of the total planar continuity.
A method of making a stack-plate comprising a plurality of single die plates oriented into face to face juxtaposition, each of said single die plates within the stack having an x-direction, a y-direction, and a z-direction, wherein said single die plates exhibit in said x-direction and y-direction to have at least 50% planar continuity of the total planar continuity.
A method of making a stack-plate comprising a plurality of single die plates oriented into face to face juxtaposition, each of said single die plates within the stack having an x-direction, a y-direction, and a z-direction, said single die plates exhibit in said z-direction of the single die plates within the stack are planar in formation and designed in the z-direction to have at least 20% depth continuity of the total planar depth continuity at any given axis in the z-direction.
A method of making a stack-plate wherein the single die plates within the stack are planar in formation comprising a combined planar continuity design of at least 35% planar continuity of the total planar continuity at any given axis in either the x-direction or y-direction and at least 20% planar depth continuity of the total depth continuity at any given axis in the z-direction.
A method of making a stack-plate die, wherein the stack-plate die comprises a plurality of single plates, each of said single plates comprised of at least one fluid stream channel and at least one flow channel, wherein said stream impingement angle upon flow channel is between 3° and 87°
