А plastic extruderis a machine that changes raw plastic into new shapes. You start with small plastic pellets. These pellets go into a hopper at the top. The pellets drop down into a long barrel. Inside, a screw turns and pushes the pellets forward. Heaters around the barrel melt the plastic. The melted plastic gets soft and sticky. The soft plastic moves to a die. The die shapes the plastic into something new, like a tube or sheet. The shaped plastic comes out of the machine. It cools down and gets hard again. Now it keeps its new shape.
