Mold design requires careful consideration of the shrinkage rate, as it directly affects the size of the final product. By adding the appropriate shrinkage rate to the initial product size, one can determine the required size of the mold. Therefore, it is crucial to take into account the key factors influencing the shrinkage rate during the mold design process.
