Scale effect in design of the pre-stressed micro-dies for microforming Wojciech Presz Institute of Manufacturing Technologies, Warsaw University of Technology – Narbutta 85, 02-524 Warsaw, Poland. DOI: https://doi.org/10.7494/cmms.2016.4.0589 Abstract: In dies for cold extrusion permissible internal pressure may be increased by the use of one or two shrink rings. Such design creates tensile stresses in … Read more
