Density Distribution and Resin Migration Investigations in Samples of Sand Core Made by Blowing Method
Journal of Casting & Materials Engineering
Resin migration in a core can occur during the core production process performed by blowing methods in which the core sand is transported into the core box as a two-phase sand-air flux characterized by various working parameters (working pressure, shooting time, volumetric concentration). This migration is the result of the resin being blown off from the matrix grain surfaces by compressed air. The methodology of the investigation of this effect developed at AGH University of Science anddoi:10.7494/jcme.2017.1.3.70 fatcat:ns6whiz7gnbmtdynv32uucqjhe
