Through mold temperature control a uniform temperature level is reached on the mold surface relatively quickly. Particular challenges include the size and 3D complexity of the molded part, the high shot weight of around 12 kg, precise back-injection of the aluminum sheet for the battery and integration of the GIT process for the reinforcing channels. Many multi-cavity molds utilize a naturally balanced runner layout where the flow distance is the same to each cavity, Figure 4. The size and weight of the mold is also an important factor to consider.
