What is the role of injection mold flow analysis?
Mold flow analysis can know whether the product has filling problems. For example, whether the product has short shots, bubbles, and unbalanced filling during the injection process can be determined by carefully analyzing the filling curve. In the mold flow analysis, you can change the position of the injection mold gate, injection speed and other processing conditions, so that you can know whether these problems can be improved or corrected.
Mold flow analysis can know whether the product is full. It can also provide other useful information such as the required maximum injection pressure and clamping pressure to provide a reference for us to choose an injection molding machine.
Mold flow analysis can calculate the efficiency of the cooling circuit. Adding cooling analysis to deformation analysis can increase accuracy. Since the cooling water circuit is difficult to modify once it is completed, this type of analysis is very useful before opening the mold.
Can predict whether the product is deformed. The absolute value of the deformation is predicted and analyzed. The prediction of the deformation can be used to compare the gate position, wall thickness changes or design changes.
Can be used to check and correct problematic mold prototypes. The problem in detecting injection molds is to use mold prototypes to do "short shots". Mold flow analysis can determine which changes will be effective and faster and cost less than mold repair.
To be simple, some easy products we do not need mold flow analysis such as household mold, pet preform mold , it is important for us to make some big products like automotive molds and home appliance molds.
