Internal finishing of cooling channel in molding die with free abrasive grains

Effects of face protuberance on internal face in curvature channels

Abstract

This study deals with internal finishing of cooling channels in molding dies with free abrasive grains. Fluid flow in the cooling channel was simulated, and the influence of the internal face protuberance on the finishing performance of curvature channels was investigated experimentally. The results showed that the internal face roughness was improved significantly by the effect of spiral flow of the fluid. The application of face protuberance was effective for improving of the face condition in the cooling channel.
