You’re right, it does require highly specialized equipment to make the cones. We did all of the product development and most of the equipment development here at AIB International. This is not to say that you couldn’t make your own version of the product. For openers, think of a mould, shaped like an inverted cone, take a nery thin pizza crust that is just barely baked (think of a tortilla) and now form it like a cone by spiraling it around your fingers. Place this on the mould, then place a metal ring around the crust to hold it together and place it back into the oven for baking until crisp or something close to it.
Remove from mould and you have your cone ready to fill.
There are probably a bunch of other ways to do it too, but this should get you thinking.
