How To Get Your Desired Intricate Metallic Design Made?

By October 13, 2021 No Comments

Any simple or uncomplicated metallic design can be achieved through machining but when it comes to complex and intricate metallic designs one has to go searching in order to find out any procedure that can help in achieving the desired intricate metallic design. However, searching for that one perfect procedure will take one to the unique and conventional method i.e., of powder metallurgy. Powder metallurgy is the only procedure that can help in facilitating individuals in achieving their desired metallic design. So, if one wants to get some complicated metallic designs made then powder metallurgy is the one and only solution. Powder metallurgy has helped to make metallic parts for so many industries like automotive, nuclear, construction, etc. are few of them.

Powder Metallurgy Process to The Rescue:

The process of powder metallurgy involves a step-by-step method that has to be followed exactly in order to attain the desired metallic design with great metallic strength and modified metallic properties. The process is divided into three main steps. The initial step is to get the powder out of solid metal by melting it, the next step is the casting of powdered metal to give it the desired shape, the final step involves the heating of casted metal powder to solidify its shape by bonding them together. Let’s have a look at what goes on while carrying out the process of powder metallurgy;

Powder Formation:

Solid metal cannot be just turned into a powder so in order to carry out the powder metallurgy manufacturing processes first of all the solid metal is melted to the point that it becomes molten. Now in order to get the powder out of molten metal we have to break it into atoms for that either molten metal can be poured into a centrifugal machine and the molten lava is atomized and small droplets are collected in the basin attached outside the centrifugal machine. These droplets while dropping on the surface of the basin come in contact with cool air and are turned into powder. The other way and also the conventional way of forming powder out of molten lava is by dropping the molten lava from a height and placing jets of cool air from one direction at some lower height. The jet of air applies pressure on molten lava and small droplets of it are collected on a cooling disc placed in the opposite direction of the jet of air at the same height. The droplets are condensed onto the cooling disc and turn into powder. The disc is attached to a vibrator which vibrates off the powdered metal from the cooling disc and it is then collected in a pan placed below the cooling disc.

Molding Of Powdered Metal:

The powdered metal is then cast and for that first, a mold is made of the desired shape and then the powdered is filled in it. When mold is filled completely from top to bottom then it has to be vibrated to remove any air trapped in between the powdered metal. The casting is done here.

Heating Of Powder Filled Mold:

The powder-filled mold is then heated at a maintained high temperature and pressure is also applied. The high-temperature heating allows the powdered metal to bond completely. This bonding of powdered metal hardens the powdered metal into solid metal. Therefore, the desired shape is attained. Furthermore, some optional steps of secondary finishing and machining are also followed sometimes. The final product is obtained in perfect shape with much greater strength and improved metallic properties.

Powder Metallurgy Is Beneficial:

The procedure of powder metallurgy is very beneficial and has also advanced with technology. This process doesn’t involve any unwanted loss of material in its manufacturing. It increases the strength of metal, makes it more flexible, and improves its properties to a greater extent. It is very economical for large scale productions. It opens doors for all the new design possibilities. These were the major benefits to list down.
