Theoretically possible, but in practice it cannot be transported by air.
Currently, many mainline passenger aircraft have cargo warehouses with a carrying capacity of 20 tonnes. However, due to the cabin layout, it is difficult to say whether large molds can be accommodated. Nowadays, small containers suitable for the cabin are generally used. Even if it is installed, the aircraft attitude still needs to be considered, and ordinary forwarders simply cannot take care of it. This is equivalent to chartered transportation. Whether it is cost-effective should be carefully considered.
At the time, I saw that the standard loading plan of the An-22 was a wagon, which was very shocking, in fact, it had just ranked among the top ten Hercules aircraft in the world.
If long distance transport is necessary, the transland port is safer. If the goods are extremely long, such as large wind turbine blade molds, special transportation by out-of-bounds vehicle must be arranged. If possible, shipping takes a little longer, but the price is cheaper.
