Abstract

Abstract: This paper introduced the extrusion technology of profile with cooling in mandrel. The theory and advantages of extrusion by cooling in mandrel and the technical realization were discussed. The key point to be controlled on production chains was introduced. It was showed that this mold process could increase the cooling efficiency and molding effect, and increase the production rate and product quality of the profile.

Key words: extrusion, mandrel, cooling inside, profile
