These two guys are showing us what the actual "molds" look like for two of their current products. The molds slide in to the huge machine(s), so when changing products, all they have to do is change the mold inside, not the entire machine. Each of their 15 large machines cost an average of $250,000. Hemingway has 1,500 molds on-site but TW world-wide has 9,500 molds in all. Wow!!!
