Plastik Enjeksiyon Kalıplamada Farklı Soğutma Sistemlerinin Karşılaştırılması

Abstract

Injection molding is preferred for plastic products due to its high efficiency. However, one of the most important factors after injection is the cooling of the part. Therefore, the cooling process considers being an essential part of the total molding time. Generally, the cooling process in plastic injection molds is done by circulating the cooling liquid through the holes opened in the radial and axial direction on the mold. However, in cases where the cooling is not at the wanted level, the efficiency is increased by placing high thermal conductivity coefficients materials in the molds. With the development of manufacturing methods, conformal cooling systems with cooling channels that follow the molded part geometry have emerged as an alternative to this method. However, this is an expensive method, and studies are ongoing. In this study, the mold cooling times were analyzed and compared with the help of the MoldFlow analysis program on a sample part with a conventional cooling system, as a result of placing a conformal cooling system and a material (insert) with a high thermal conductivity coefficient in the mold.
