Question

There are alot of shows these days that show how things/food are made. Who exactly builds the very specialized machines that make only popsicles or makes only tennis rackets? Is it made by an engineering group that custom makes machines for a client , whatever they plan on making? Or is it more of taking, as I said earlier, an existing popsicle making machine, and then tweak it a bit to fit whatever different kind of frozen confection needs to be made? Cause sometimes you look at a factory machine in operation, like where they make empty soda cans, and it is jammin', making like 100 cans a minute...

Answer 1

They are often custom-made, either by external machine or equipment shops, or by an internal machine shop. For common items such as cans, commercial canning systems are available and don't need to be custom made.
