In the past few decades, several novel injection molding techniques have been developed in pursuit of better quality and cost savings. Cooling is the most dominant stage in injection molding in terms of quality and cycle time. Therefore, how to design an efficient cooling system is always critical. Among various cooling solutions, conformal cooling has gained importance due to proven success in cost and cooling time reduction.
CAE software can successfully assist in evaluating the effectiveness of cooling layout designs and verify potential design problems at early stage. For example, physical properties such as pressure, temperature, and flow velocity can be presented in three dimensional inside cooling channels. Users can detect potential design problems based on analysis results. In addition, through cooling time prediction, users will perceive the effect of cycle time on a cooling system.

With Moldex3D’s latest technology in predicting flow behavior inside cooling channels, designers and molders can utilize additional results such as streamlines and velocity vectors to optimize their designs. Figure 1 shows the velocity vectors inside a twin-spiral cooling channel and Figure 2 shows the streamlines inside a baffle cooling system. All results are three-dimensional providing the best reliable information.
