Mold?ow Plastics Insight
Mold?ow Plastics Insight? (MPI?) software represents the most comprehensive suite of de?nitive tools for simulating, analyzing, optimizing, and validating plastics part and mold designs. Powerful and easy to use, MPI offers nineteen distinct modules that can be used to simulate nine unique molding processes.
The Benefits of Predictive Analysis
To avoid the high costs and time delays associated with problems discovered at the start of manufacturing, it is necessary to consider the combined effects of part geometry, material selection, mold design and processing conditions on the manufacturability of a part. Using predictive analysis tools to simulate the injection molding process,companies can evaluate and optimize interactions among these variables during the design phases of a project before production begins, where the cost of change is minimal and the impact of the change is greatest.
With MPI analyses, you can simulate the ?lling, packing and cooling phases of thermoplastics molding processes using materials with or without ?llers and ?ber reinforcements,as well as predict post-molding phenomena such as part warpage. You can also simulate material ?ow and cure of reactive molding processes.
MPI also offers the world’s largest material database of its kind with more than 7,800 thermoplastic materials characterized for use in plastics CAE analysis, as well as thermoset materials, coolants and mold materials, and injection molding machine-speci?c analysis capabilities.
MPI is highly acclaimed for its speed and accuracy and addresses the broadest range of design geometry types and manufacturing issues associated with plastics molding processes.
MPI simulation tools are made all the more powerful because of the wide breadth of geometry types that can be used. MPI allows you to directly analyze traditional midplane ?nite-element mesh models, solid models of thin-wall parts using MPI/Fusion solvers, and solid models of thick parts using MPI/3D solvers.
Traditional Midplane Solutions
A midplane mesh represents a three-dimensional part with a two-dimensional, planar surface with a thickness property assigned to this surface. Using a midplane mesh works best when the part being modeled is a traditional, thin-walled injection molding application. To increase your productivity when creating and analyzing such models, the MPI/Midplane Generator can be used to automatically generate a midplane mesh and assign proper element thickness to ensure accurate analysis results.
MPI/Fusion Solutions
MPI/Fusion solutions are based on Mold?ow’s patented Dual Domain? technology, which represents a three-dimensional part with a boundary or skin mesh on the outside surfaces of the part obtained from a common CAD translation model such as STL or IGES format. This allows you to analyze CAD solid models of thin-walled parts directly, resulting in a signi?cant decrease in model preparation time. The time saved allows you to analyze more design iterations as well as perform more in-depth analyses.
MPI/3D Solutions
Using a proven solution technique based on a solid, tetrahedral ?nite-element volume mesh, MPI/3D solutions allow you to perform true, three-dimensional simulations on geometries that do not conform to the criteria de?ning traditional, thin-wall designs. MPI/3D works well with thick and solid parts such as electrical connectors, thick structural components, and those that have extreme thickness changes.
Optimize Total Solution Time
Total solution time includes both model preparation and analysis run time. These factors are highly dependent on complexity of part and mold design as well as user-selected analysis options. Mold?ow products offer you a wide range of software solutions so you can obtain the most accurate results possible in the shortest period of time for each unique application.
Mold?ow Plastics Insight software provides in-depth process simulation tools so you can predict and eliminate potential manufacturing problems and optimize part design, mold design and the molding process itself. MPI analyses give you de?nitive solutions that address a comprehensive range of plastics molding processes and state-of-the-art process applications.
MPI/Synergy is the pre- and post-processor that supports all MPI analysis modules. MPI/Synergy provides powerful work?ow and productivity tools with all of the necessary capabilities for modeling, meshing, mesh editing, model validation, job setup, job control, results visualization and report generation in a single, easy-to-use environment.
Plastic Flow Simulations
MPI/Flow simulates the ?lling and packing phases of the thermoplastics injection molding process to predict the ?ow behavior of plastic melts so you can ensure that parts of acceptable quality can be manufactured ef?ciently. Using MPI/Flow, you can optimize gate locations, balance runner systems, evaluate processing conditions to determine a robust molding window, and determine and correct potential part defects.You can simulate innovative applications including insert overmolding and two-shot sequential overmolding processes. You can also analyze the effects of non-uniform mold temperatures, determine optimized valve-gate timing sequences, compare ?ow through hot versus cold runner systems, and analyze Dynamic Feed applications.
MPI/Gas simulates the gas-assisted injection molding process, where gas, usually inert nitrogen, is injected into the polymer melt. The gas drives the polymer through the mold cavity to complete mold ?lling and create a network of hollow channels throughout the component. Use MPI/Gas results to help determine where to position polymer and gas entrances, how much plastic to inject prior to gas injection, where to place gas channels, and how large to size them.
MPI/Co-Injection simulates the sequential co-injection process, where a skin material is injected ?rst, followed by he injection of a different core material. You can view the advancement of the materials in the cavity and see the dynamic, changing relationship between skin and core materials as ?lling progresses. Use results to optimize the combination of wo materials while maximizing the overall performance/cost atio for the product.
MPI/Injection Compression simulates processes where polymer injection and mold compression occur simultaneously or sequentially and allows you to program the compression phase to begin before, during, or after polymer injection using timer controls built into the software. Use results to comprehensively evaluate candidate materials, part design, mold design, and process conditions.
MPI/MuCell simulates the microcellular (MuCell?) injection molding process, in which a supercritical ?uid such as carbon dioxide or nitrogen is mixed with molten polymer and injected into the mold to produce microcellular foam. With MPI/MuCell, you can evaluate the feasibility and bene?ts of using this process versus traditional injection molding. Additionally, you can optimize the part design and the process settings by reviewing the various analysis results.
MPI/Design-of-Experiments lets you set up and perform a sequence of analyses automatically, varying the parameters you specify, such as mold and melt temperatures, injection time, packing pressure and time, and part thickness. The program automatically arranges the experiments and statistically analyzes the results to help you optimize processing parameters and ultimately, the molded part. Results include single-point quality indicators such as volumetric shrinkage, injection pressure, clamp force and ?ow-front temperature, as well as displays of ?ll time, pressure, and temperature distributions.
MPI/Optim allows you to perform an injection molding machine-speci?c analysis, which takes into account the actual machine response time, maximum injection velocity, and the number of steps that can be programmed for velocity and pressure pro?les on the machine controller. Use the results to achieve uniform ?ow front velocity and temperature pro?les through the injection molding machine nozzle, the mold feed system, and the part
Mold Cooling Simulations
MPI/Cool provides tools for modeling mold cooling circuits, nserts, and bases around a part and analyzing the ef?ciency of the mold’s cooling system. MPI/Cool simulations allow users to optimize mold and cooling circuit design to achieve uniform part cooling, minimize cycle times, eliminate part warpage due to cooling factors, and decrease overall manufacturing costs.
Structural Integrity Simulations
MPI contains a broad range of simulation products speci?cally developed for predicting the structural integrity of injection-molded plastic parts.
MPI/Warp predicts the shrinkage and warpage of plasticparts based on process-induced stresses. It is also possible to predict the spatial deviation of an injection mold core due to non-uniform pressure distribution. MPI/Warp results help you understand the causes of warpage, display where it will occur, and allow you to optimize your design, material choice and processing parameters to control part deformation before the mold is built.
MPI/Fiber predicts the ?ber orientation due to ?ow in ?ber-?lled plastics and the resultant mechanical strength of the plastic/?ber composite. It is important to understand and control the orientation of ?bers within ?ber-?lled plastics to reduce shrinkage variations across the molded part to minimize or eliminate part warpage.
MPI/Shrink predicts polymer shrinkage based on the effects of processing and grade-speci?c material data and offers a true prediction of linear shrinkage independent of warpage analysis. Because plastic parts shrink as they cool, it is essential to accurately account for this shrinkage in the design of the mold so that critical product tolerances can be met.
MPI/Stress predicts the post-molding performance of plastic parts when subject to various forms of external loading. The analysis considers the effects of plastic ?ow during injection molding and the resultant mechanical properties on the component’s structural integrity.
Reactive Molding Simulations
MPI/Reactive Molding simulates the ?ow and curing othermoset resins in a variety of reactive molding processesincluding thermoset and rubber injection molding and RTM SRIM applications. Use results to evaluate manufacturabilityminimize cycle times, and optimize processing conditions.
MPI/Microchip Encapsulation simulates the encapsulation of semi-conductor chips with reactive resins, including paddle shift and wire sweep predictions. Analysis results help you design the encapsulation package, tool, leadframe and wires, as well as optimize processing conditions, including mold temperature, ?lling time, ram speed pro?le, and curing time.
MPI/Under?ll Encapsulation simulates the pressurized under?ll encapsulation process (also called ?ip-chip encapsulation) to predict the ?ow of the encapsulant material in the cavity, between the chip and the substrate.
To install and run Mold?ow Plastics Insight software, your computer should have at minimum a 500-MHz processor with at least 2 GB of free disk space and 256 MB of RAM. Actual requirements to achieve optimal performance may increase signi?cantly depending on the size of models you are analyzing, the type of analysis and the number of simultaneous analyses being run.
