Introduction to rolling and extrusion forming of powder metallurgy technology

With the development of the times, powder metallurgy has become an indispensable existence. Then let's share the introduction of powder metallurgy technology rolling and extrusion molding.

As follows:

1： Metal powder rolling

It is a powder metallurgy process in which metal powder is produced into continuous plates and strips through a series of rolling processes. According to the different rolling positions, it can be roughly divided into vertical rolling, horizontal rolling and rolling with a certain inclination. The metal powder rolling mechanism is different from the traditional compact rolling mechanism. It is applicable to the condition that the powder quality remains unchanged before and after powder rolling.

2： Powder extrusion molding

It refers to a powder metallurgy forming method that powder or powder compacts are extruded into billets or products through the specified film pressing nozzle under the action of pressure. According to different extrusion conditions, it can be divided into plasticized powder extrusion and hot extrusion molding.

3： Advantages of plasticized powder extrusion

It can form complex cross sections; The amount of binder used is small; It can form hard powder; Uniform molding density; Manufacture of slender components; Economical and labor-saving.

4： Hot powder extrusion

It refers to the metal powder compacts or the powder is heated in the package, and then squeezed at a higher temperature. Hot powder extrusion provides a unique method that is difficult to form by other methods, and has been applied to open pipes, wires and parts with complex sections.
