【正文】 or quality (weld lines, airpocket etc), material selection, structure optimization (thickness), the gate location and port (cold and hot runner) optimization problems. AMI for injection molding the thorough analysis and optimization, it is the most widely used worldwide mold flow analysis software. For the user to AMI geometric shapes, materials selection, mould design and processing parameter optimization for high quality products. MSA users can ABAQUS software ANSYS in structure or software 32 analysis considering injection molding process for injection molding product structure. Through the MSA will anisotropy attributes and AMI or obtained by analyzing the AMA flow characteristics of input to structure analysis software, the user can obtain more accurate design of plastic products, mechanical property and mechanical properties, can at the early design stage of the product design better optimized design of may and reduce the change. Autodesk Moldflow materials laboratory (MPL) for all users of the art of Moldflow material testing service, expert material data fitting service, and continued to provide all analysis software Moldflow most widely material database. Autodesk Moldflow MDL) is too Link (Moldflow product series of important data Link tools. Through various products not only can easily Moldflow IGES, Stereo, read presented. the Lithography (STL format) 3D model, but also directly read Parasolid (UG), Pro/E, Ideas, such as CATIA, Solidworks highend CAD software to the latest version of the original files, and other 3D model for software Ansys, such as structural analysis of CAE Nastran, and Patran ABAQUS, and lsdyna, Hyper as the mesh generating webmaster can also pass to MDL for further analysis of AMI. In except to support data model transformation after the traditional functions, but also increased the following new features: (1) to CAD entity driver is the core of grid generation way, (2) ponents (assembly model) and the grid directly import automatic dividing, (3) direct mesh division 3D entity, (4) long and narrow features removal. Autodesk Moldflow CAD Doctor is a powerful tool that can check to model, repair, adjust and simplified entity model or IGES surface model, through bining with the Doctor can MDL, CAD import all the mainstream of 3D CAD/CAM software generation 3D models. The Doctor generate high quality Cad entity or surface model can directly into in order to AMI or AMA construct rapid high quality of the finite element mesh model, to improve the speed of processing in before and effectively improve the accuracy of analysis. 33 Current CAD Doctor has fully support 64bit operating system, users can easily super model of work. The main function of Cad Doctor include: (1) to IGES surface model of automatic repair and suture, (2) of the surface model or geometric structure adjustment of topological relationships, (3) characteristics such as small round, bevel, convex platform, indentation, round hole and characteristics of the automatic recognition and removal, (4) to YinWen surface characteristics of rest respectfully or automatic recognition and removal, Automatic extraction (5) can be used to die (from formwork directly from water or flow structure). Normally, the most mon AMI (MPI) to simulate the process of injections, which get the best gate number and position, reasonable flow system and cooling system, and the cavity dimension, gate dimensions, port size and cooling system, and optimize the size of injection process parameters are optimized. AMI not only can consider to traditional problem analysis, Injection Molding twomaterialinjection were (Over), Gas Injection Molding (Gas), assistant Injection Molding (Co ), Injection Molding Injection pressure and Compression () (), Mucell foamed optical Birefringence analysis (Birefringence), the recent rise of hot runner system also can feed on the dynamic simulation of AMI, also can be analyzed and the reaction of thermosetting Molding materials of electronic chips, AMI widely used in packaging, medical, automotive, aerospace and 3C with plastic packaging etc all related industry. The latest version for AMI, AMI products include the following analysis module. ● AMI/Synergy, it is a front and rear processor, support the MPI series products of all analysis module. ● AMI/Flow and pressure filler can Flow equilibrium analysis, temperature, pressure, clamping force, weld lines, exhaust and process conditions optimization. ● AMI/Cool optimization design, mold cooling system is analyzed in 34 order to realize accurate realization uniform cooling or the minimum size of the product shape cycle. ● AMI/Warp analysis of warping deformation and warpage deformation shapes whether meet the design requirements, and also can analyze product shrinkage. ● AMI/Stress integration of molding structural analysis, thus influence on the overall structure of more accurate evaluation. ● AMI/Fiber glass Fiber strength and stiffness of the product has great influence, through the glass Fiber analysis can assess fiberglass products structure deformation of the MHD effect. ● AMI/on bining process condition optimizing mold cavity dimension design, analysis of the actual shape material shrinkage. ● AMI/Gas optimization design of airway and gasassisted technological condition, ensure the feasibility of Gas assist product design. ● AMI/Co Injection also said that in a sandwich Injection, a core materials into another kind of materials in order to meet the requirements of quality and cost. ● AMI Injection/Compression stress requirements for the optical products such as low CD, plastic lenses and ultrathin product to have the important meaning. ● AMI/MuCell optimization analysis, in order to reduce the physical foaming product, red
