In high-speed polyolefin extrusion, the phenomenon of melt fracture—commonly appearing as sharkskin or surface roughness on the finished product—presents a critical barrier to increasing production ...
A MIT Media Lab graduate student has developed a tulle-like textile – DefeXtiles - by controlling a common 3D printing defect, the under-extrusion of polymer filament. Jack Forman used a standard, ...
This text focuses on advanced methods for predicting and avoiding the occurrence of defects in manufactured products. It covers the major manufacturing operations, and considers conventional and new ...
Aluminum is particularly well suited to the extrusion process due to its excellent plasticity at extrusion temperature. Only a minor degree of work-hardening takes place at this temperature and ...
Researchers have discovered the primary mechanism driving the extrusion of dying cells from epithelial monolayers. Researchers from the Mechanobiology Institute, Singapore (MBI) at the National ...
Defects in angioplasty balloon material, which result in product discards, may represent a significant portion of production. Abbas Tcharkhtchi and Erik Andersen Angioplasty balloons are critical ...
Extrusion machines force or pull unformed material into alignment guides and shaped dies to produce lengths of stock forms and cross-sectional shapes. They are used mainly in the plastics, metals, and ...
