ABSTRACT

However, method to create conformal cooling system is more complicated than that of conventional cooling system which consisted of straight drill holes [8]. For conformal cooling system, DMLS (Direct Metal Laser Sintering) technique is used to make injection mold inserts. The advantages of this technique were to create cooling channels with different cross sectional shapes such as circular, oval, rectangular, etc. Furthermore, DMLS can be used to create coolant flow line along with shape of plastic part [9].
