Design and Analysis of an Aluminium Die Casting Die for a Compressor Rotor

Abstract

Pressure die casting is a process in which metal, heated above the solidus, is introduced into a metal mould or “die”, and is subjected to pressure in order that it shall conform to the exact shape of the mould impression or “die cavity”.

Die casting components play an important role in every aspects of modern world. Their influence ranges from house hold utensils to automobile components. Requirement of today’s world is production, accuracy and interchangeability, which helps to meet the competition in the world. In order to meet these challenges die casting processes play an important role in production.

For die casting components there is no need for further machining and getting components with good surface finish. Automobile industry is one where the life of product is short.

          The components are rejected due to hot spots, shrinkage, porosity etc. Modification is done to reduce the above said defects which resulting in reduction of rejection of rotors and increasing the quality of the rotors and with the modification of the die casting die with single cavity die with multi cavity die which leads to increase the production rate of the rotors.
