Plastic extrusion line

If you did, have you ever wondered how plastics are actually manufactured - from straws, toys to car parts? A very common method of manufacture for these items is by use of a plastic extrusion line. This machine is significant because it can produce stretch plastic products to any size and shape you want. This process is utilized in the production of many plastic products that are seen and used by people every day. 

A plastic extrusion line consists of many mechanisms and pieces designed to work in concert together. A hopper, which is a large vessel into where the plastic pellets are poured through. What are pellets: These plastic pieces will be the final product. Then you have a barrel, and thats for the magic part. This is a piece of the machine where it gets super hot and ends up melting down to kind of stringy plastic. Finally, there is a die. During this time, the die molds the desired shape of each plastic piece into its finished form using melted plastic as a similar tool to how cookie cutters mold dough.

How Does A Plastics Extrusion Line Work 

So, in the hopper there is plastic pallets. The pellets will begin drooping into the barrel once they are inside The screw turns, causing the molten plastic to be pushed along inside the barrel. Special heaters are used to warm up the barrel as pellets pass through it. This in turn heats the plastic pellets to a melting point, where they become thick and liquid. 

The molten plastic would then reach the die and molded into a specific shape. The die functions as a cookie cutter, except it doesn't cut dough -- instead hot molten plastic is pressed through the opening to form whatever shape of piece needed. These plastics cool, and as a result harden after they take their new shape. If you can see, the cooling process is very crucial for preserving its new form.
