Filling Analysis simulates how plastics will fill in the mold under given product design, material, machine, mold, gating, and processing conditions. Filling analysis is the first step of any injection molding simulation and does not include packing, cooling, and warpage analysis and is generally required to perform any further analysis of any injection molding simulation. You should note that while it is the first step, it is probably the most important analysis as it can help identify many processing issues such as air trap, hesitation, weld lines, flow balance, racetracking, packing issues, some indication of cooling and warpage issues. Filling analysis can also help identify many other daily molding issues of shear stress, gating blemishes, flow marks, jetting, shear heat, venting, clamp tonnage, pressure imbalance, cavity pressure, cavity imbalance, and more. Ideal Tech has performed over 5000 different analysis of plastics parts and is the leader for these services. Mold packing analysis is the next step of analysis and is needed to complete the steps of filling of parts. Without packing analysis, mold filling is actually incomplete because packing stage is important for proper completion of filling of plastics parts, packing of the cavity regions, clamp tonnage, and in general complete behavior of plastics during cooling and post molding dimensional issues. Ideal Tech engineering always perform filling and packing analysis of all moldflow projects. Fill and Pack analysis are together termed as “flow analysis” in Autodesk Moldflow analysis simulation.
