RocTool is an innovative company that specializes in licensing its rapid molding technologies for the composites industry. With COMSOL, we developed the Cage System, where the composite material is placed within the mold that then presses down on the material while induction currents heat the two surfaces of the mold.
In the composite-molding business there is no such thing as a standard product; each mold must be designed individually based on the customer’s material and product specifications. This is where COMSOL Multiphysics plays a crucial role.
With this model, engineers can determine the optimal size of the coil, its placement, heating material properties and the optimized cycle time. After modeling, RocTool engineers can tell the client that the process will result in a given temperature cycle, that molding will take a given amount of time, and they can also give a reasonable estimate of what the parts will cost to manufacture.
