One of the key elements of any injection molding process is the in-mold cooling process of the polymeric fluid which is transferred into a mold. The in-mold cooling process incorporates the heat transfer between the molten polymer and the mold so that the polymer solidifies to adopt the mold shape. Due to the complex temperature and time-dependent structure of polymers, the parameters involved in this process are many and the analysis of the problem is complex. Considering this, our research will study the feasibility of a novel approach to improve the time of cooling while retaining the desired properties of the solidified polymer.

任何注塑工艺的关键要素之一是聚合物流体的模内冷却工艺 其被转移到模具中。模内冷却过程包括熔融金属与熔融金属之间的热传递， 使聚合物固化成模具形状。由于复杂的温度 和时间依赖的聚合物结构，在这个过程中涉及的参数很多， 问题是复杂的。考虑到这一点，我们的研究将研究一种新方法的可行性， 冷却时间，同时保持固化聚合物的所需性能。
