Training data are in [minTrain maxTrain], test data are in [minTest maxTest] such as 30% (for instance) of the data are outside the range [minTrain maxTrain]. It is known that neural networks do not work well in extrapolation. How can I improve the network predictions in this case just to have acceptable results. Do you have any idea?

Use whatever info you have to fabricate additional data.

Not much more to say. If theory and/or non-training data gives you some idea of data characteristics beyond those limits, use tat info to fabricate training data with those characteristics.
