Fusion launched in 2020, analysis techniques, enabling users do not need to extract the neutral surface can be analyzed, to overe the reconstruction of the geometric model, thus greatly reducing the burden on the user modeling. Grid is also a triangular element, and its principle is to mold cavity or the products in the thickness direction is divided into two parts, finite element mesh on the surface of the cavity or the products. In the flow process, the upper and lower surface of the plastic melt at the same time two and to coordinate movement of the simulation shown . Clearly, Fusion technology, the surface of the grid is based on the neutral surface is still not solve the fundamental problem the neutral surface, so doublesided application of the principle of streaming technologies and methods applied in the surface flow with no difference in the nature, the The difference is twosided flow using a series of related algorithms, will flow along the surface of the singlestranded melts evolved along the upper and lower surface of the coordination of the flow of dualstream. Doublesided flow of technology39。 and domestic in the Eighth FiveYear period began research in this area, and now Huazhong University of Technology HSCAE software and Zhengzhou University, Z Mold software in China in the leading position. Moldflow software is specialized in injection molding CAE software and consulting for Moldflow39。 Injection Molding CAE Technology 0 Introduction Plastic products from product design to production, including molding plastic products design, mold design, mold manufacturing and injection molding process parameters and several other main areas. The traditional injection mold design mainly rely on the designer39。s Taiwan region Moldexpeer software applications are relatively wide。s Fusion analysis Fusion (double flow) analysis technique is based on Moldflow39。s 3D (3D) analysis technology uses a true threedimensional solid model flow analysis techniques, through rigorous theoretical derivation and repeated verification, the inertial effect, nonisothermal flow, taking into account factors such as finite element analysis, the melt thickness direction of the physical quantity changes will no longer be ignored, can be a more prehensive description of the process of filling flow phenomena, so that results of the analysis more realistic conditions, applicable to all plastic products. Its threedimensional grid is from the fournode tetrahedron unit. And using the new 3D stereoscopic display technology, can quickly model clearly shows that internal and external flow field, temperature field, stress field and velocity field such as analysis results. For the abovementioned results of the analysis can also be used such as bit lines or equipotential surface display, so that physical models and external changes in the variables show more clearly the case, Moldfiow also offers animation capabilities, through 3D animation display plastic melt in the changes in the flow cavity, allowing users to more intuitively see the design and manufacturing process may encounter problems. But the 3D technology, meshing demanding, more plex equations to calculate the amount of large, long duration and the putational efficiency is low, not suitable for short development cycle and need to be repeatedly revised by CAE verification injection mold design. Therefore, the current peration rate of the technology is not very high, but it will eventually replace the surface flow of technology and doublesided streaming technology. 7 Development Trend of Injection Molding Injection Molding CAE technology, whether in theory or in t
