Definition of precision cold extrusion

Definition of Precision cold extrusion is an important part of precision plastic volume forming technology. Cold extrusion is to put the metal blank in the cold extrusion mold cavity at room temperature, The press machine will punch the blank by fixed mold to apply pressure to the blank so that the metal blank gets plastic deformation and be shaped into different part. Its precision is higher and the producing speed is faster.

Precision cold extrusion process

We can divide precision cold extrusion into three main processes: forward extrusion, reverse extrusion, and lateral extrusion.

Forward extrusion: The material flows in the direction of the displacement of the punch, it is pressed into the die through the hole, the diameter of the rod/tube can be reduced, the billet (tubular) is extruded through the forward extrusion die, the force is A punch and mandrel acting as a pusher is applied, reducing the outer diameter as the tubular portion elongates.

Reverse extrusion: The material flows in the other direction of the punch displacement, and the billet enclosed in the die is forced to flow backwards from the annular area located between the die and punch.

Lateral extrusion: The material flows perpendicular to the displacement of the punch, and the material surrounded by the punch and die is forced to flow through radially placed holes.

There are difficulties in the application of precision cold extrusion.

The difficulty in the application of precision cold extrusion technology is that it has high requirements for molds, requires a large tonnage press, and has high costs. Surface treatment is required before extrusion, and it is not suitable for processing high-strength materials. Poor, the residual stress of the part is large, which will cause deformation and corrosion resistance of the part.

Another definition of precision cold extrusion

Precision cold extrusion is also defined as a compression molding process, the material is a billet, the process is performed at room temperature, and deformation heating is the process of converting deformation work into heat. Typically, a punch is used to apply pressure to a closed blank in a stationary die. This pressure can be applied partially or fully as desired.

Frequently Asked Question

Do you have any question?

This is one of the most common questions, especially by then newbies trying to find out more about forging technology. There are various types of forging, and cold forging is just one of them. As the name suggests, cold forging is all about the forging method that works on the metal at room temperature. Unlike hot forging, where the metal is heated to crystallization temperature, or warm forging, where the metal is slightly heated, the cold forging method works formed metal when at room temperature. That’s why it is referred to as cold. However, there are cases when the metal could be heated slightly if it is too hard.

There are so many questions on the operation of the cold extrusion forging. Different approaches could depend on the kind of item being formed, but the principle of operation remains the same. Like other forging methods, the technique works on compressing the metal or the billet against the molds or dies to form the desired shape. The billet can be any metal that can be cold forged, and the mold is always made from a stronger and harder metal. This enables it to withstand the high compression force that deforms the metal being forged.

There are several things that you need when it comes to doing cold extrusion forging. One of them is the right material for the kind of products that you want to make. If you have a range of materials that you can use for this type of forging but soft metals such as aluminum are the most common. Apart from the materials, you need molds and hydraulic press machines. The molds form the desired products’ shapes while the press machine produces the required compression force to deform the billet. These are basic things you need to know about cold extrusion forging.
