Significant Achievements: | ||||||||||||||||||||||||||||
| Invented Analytical Engineering, a term devoted to a scientific analysis of production primarily in the field of extrusion Invented an extrusion rate controller which cut the product temperature variability by an order of magnitude on a 150 mm extruder, significantly improving the quality control in a $40 million wire and cable facility. Designed an extruder screw which saved the wire and cable company $360,000/year in production costs. Invented “Flow Vision”, an instrument on-line for inspecting polymer melts for gels, voids, contamination and any other heterogeneity. Invented a rheological tool for measuring the degree of shear damage done to polymers during processing. This includes the level of fragmentation and the incipient crosslinking in processing as function of shear rate. Developed ASTM Methods for analyzing plastics, D 3364 Melt Flow Analyzer, D 3591 Analysis of Formulated PVC, D 5576 Structural Entities in Polyolefins by IR, D 5477 Polymer Layers or Inclusions by IR. | |||||||||||||||||||||||||||||
