The extrusion process is widely used in the production of hollow pipes and tubes. In this article, we are going to discuss the Extrusion Process along with its Definition, Types, Advantages, Disadvantages & Applications in a detailed way.
Extrusion is a compression process in which the work material is forced to flow through a die opening to produce a desired cross-sectional shape called an Extrusion process.
In this process, the forces are applied on to the raw material by using a RAM in a closed container such that stresses induced in the material is greater than the flow stress of the material.
As the behavior of the material is like a fluid, the material can flow through the small opening available in the container, taking the shape and size remains the same as that of opening.
For example, Squeezing toothpaste out of a toothpaste tube.
To understand the working principle in a better way, we need to know about the types of the extrusion process.
There are two types of Extrusion process.
Let me elaborate these types.
Setup of the Forward extrusion consists of a die, ram, billet (work material), and the container.
In forward extrusion, the direction of movement of the Ram and extruded component are in the same direction.
In the case of Forward extrusion, every point of raw material has to travel against the container wall friction for the extrusion to be taken place.
Hence, the force required for Forward Extrusion is higher than the Backward Extrusion.
The setup of backward extrusion consists of a die, ram, billet (work material) and the container similar to forward extrusion process.
In Backward extrusion, the direction of the movement of Ram and the extruded component is in the opposite direction.
In the case of Backward extrusion, the raw material can deform directly and the flow takes place through a die opening, and the required shape of the component can be obtained.
Hence, the force required for backward Extrusion is very much lower than the Forward Extrusion.
So the advantages are:
Here are some disadvantages:
The applications are as follows.

From what I can see the material comes out as a closed solid. How is a hollow tube created from this?
