On the Issue of Heat Balance of Molds for Injection Molding of Non-Ferrous Metal Alloys

Abstract

© Published under licence by IOP Publishing Ltd. The article presents a study of the thermal balance of injection molding molds. The main components of the balance equation are indicated, as well as the factors that affect them. It is revealed that the most important factor affecting the thermal balance is the material of the mold. The use of coatings applied by the method of physical vapor deposition on the forming surfaces of molds is proposed. These coatings provide a reduction in friction between the forming surface and the poured melt at the time of filling, which reduces the temperature of the forming surface by 10-12 C. Among the considered options, the most optimal indicators were for titanium and molybdenum metal nitride (Ti, Mo) N.
