Hello everybody,
After a few times away, EXApro team is back !
Here a quick presentation about the extrusion process.
Extrusion is applicable to several materials: metal, rubber, composite materials… In this article, we will focus mainly on thermoplastics extrusion.
But what is extrusion process exactly?
It is a process in which granule materials are pressured to shape them as long components.
This is a method of processing synthetic organic materials into granular state which allows the pressurized material to transform it into a long profile.
We can thus obtain through the extrusion of plastic profiles for doors, windows, pipes, sheets, wire, etc.
There are three different types of extrusion:
Film extrusion: used to make plastic films
Blowing extrusion: used to manufacture bottles
Inflating extrusion: used to produce plastic bags
Here is an example of the main parts of an extrusion line:
After receiving materials the extruder mixes and heats it, raises the temperature to push in toward the element which is going to shape the final products while cooling it down.
