The underlying concept Blow molding machines are a special kind of machinery that help to in make many things by blowing air into the hot plastic. So what's the deal with these machines, how do they work and why do they even matter?
Blow molding machines are these huge, magical machines that transform plastic pellets into cool shapes. The machine heats up plastic pellets and melts them in an oven. Next, a huge metal mold clamps down on the melted plastic. Next, air is blown into the mold, causing the plastic to puff up as if it were a balloon. When the plastic cools, the mold is opened and out comes a new, shiny plastic thing!
