A method for automatical balancing multi-cavity injection molds is presented with the aid of flow simulation. After the runner and cavity layouts are designed, the runner and gate sizes are adjusted iteratively based on the flow simulation results to make each cavity fill up automatically at the same time under the same pressure. Numerical simulation test is used to study the effects of fill time, injection temperature and mold temperature on the flow balance. The result shows that fill time has a significant impact on the flow balance.
