Probably the box thing would be a heating/cooling press, I run a few huge different ones where I work for milk, and cream, skim, whey. HTST, high temperature short time, could be seconds at temps at around 200 and then seconds later cooled back cold. Pretty high tech, but probably required of all cider mills now.
Should have pressed my own, hate paying that much.
Fly Creek is a water powered mill, has been pressing cider for 159 yrs. Haven't taken the tour or been there yet, drove by it before. Hopefully they charge less for carboys.
