How to save energy, cost, and make competitive products? Polymer processing industry has evolved dramatically during the last decade. Several new technologies were developed in order to improve product quality and save manufacturing cost. Energy topics are still hot these days since its shortage and price are increasing, not mention the impact of the environment such as global warming. That is why carbon foot print standard was regulated now. The newly developed technologies in injection molding are highly related to environmental concerns such as hot runner, conformal cooling, and variotherm – each one has been widely used nowadays. In this seminar, we will brieﬂy talk about the developing trends in polymer process. Then, each of the three topics will be discussed in details individually. 1. Conformal Cooling Cooling is a critical issue in pursuing high quality product in injection molding process. The concept from rapid prototyping had been now transformed to mold tooling. Conformal cooling is a technique to eliminate hot spots and product defects. This course will begin with the concept and theory of mold cooling – the diﬀerence between conventional and conformal cooling will be discussed. The manufacturing methods (Fig. 1) and beneﬁts of conformal cooling will then be introduced. In order to ﬁnd out potential issues or conﬁrm parameters in cooling designs, a CAE simulation technique for conformal cooling is introduced. CAE results can unveil how the designs aﬀect process and product quality. New functions in Moldex3D will be brieﬂy discussed. Finally, real cases (Fig. 2) were studied for the eﬀectiveness of conformal cooling. It indicates that conformal cooling can shorten cycle time, improve product quality, and save manufacturing costs.

Hot runner Hot runner technology has been applied to many injection products from large-sized parts (bumper, LCD panel front/back cover etc.) to small-sized parts (bottle cap, optical component etc.). It replaces traditional cold runner to solve some molding issues such as weld lines and product surface problems. And most importantly, it can save plastic material use and help protect our earth. However, a hot runner system is relative expensive and its mechanism is very extensive and mysterious. In this section, we will start from a short introduction of hot runner systems. The second part will talk about some important issues such as ﬂow imbalance, dead spot, non-uniform heating, and degradation. Then some cases (Fig. 3) will be discussed to show how to utilize CAE to revise design, improve quality, and save energy. With the advanced hot runner simulation from Moldex3D, temperature distribution can be estimated in 3D and transient. Eﬀects from each component within a hot runner system can be considered to achieve better accuracy. 3. Variotherm Fig.3 Hot runner real case study Plastic product surface problem is always annoying – weld lines, surface gloss, ﬁber exposure…etc. Variotherm is a method applied in some of the most popular applications such as ultra-book dimension control and enhancing the replication of micro injection molding. This is a technique by controlling mold temperature at diﬀerent time and space in the mold. There are various methods in this category, including RHCM (Rapid Heat Cycle Molding), E-mold (Electricity Mold), IHM (Induction Heating Mold), IR heating, and so on. In this last section, a short introduction of variotherm will be addressed which followed by the beneﬁts and common applications of this technology. The second part of this course will talk about CAE and its use on simulating variotherm technology. True 3D transient cool technology is used to have insight into the mechanisms of variotherm technologies. Some case studies (Fig. 4) will be discussed to show how to get the best beneﬁts from simulation. Again, it is another important “Green Molding“ technology which can save the cost make your product more competitive.
