Machining Powder Metal Parts: Rarely Necessary, Usually A Pain

By November 26, 2021 No Comments

Usually, the metal parts manufacturers go with the machining option of manufacturing the desired products. However, manufacturing metal parts by machining is a very wasteful process. The solid metal that is put in the machine for its processing is scraped off into a chip, and the scraped metal is wasted until the metal part achieves a perfect finish; it is scarped continuously, and at the end, the product that you see isn’t even as strong as the original metal due to over-processing of it. Therefore, what experts recommend is to carry our powder metallurgy process instead of wasting tons and tons and tons of metal in machining. The powder metallurgy process ensures zero waste of the product. It helps the metal to retain its original qualities, unlike machining in which metal loses all its properties in over-processing. Then why do people not prefer powder metallurgy more? The reason is that they complain that the product that we obtain through powder metallurgy still needs further machining to get a finished look. That they think is a pain because it is an extra step as compared to machining, which makes a product in one step. Machining powder metal parts can be avoided; how? Keep reading

There Is No Need of Machining Powder Metal Parts, how?

Machining powder metal parts feel like a pain to you, right? You can very easily avoid it by taking some aspects into your consideration. You put powder metal into the die for casting and apply pressure on it with a punch so that there remains no gap between the powder. That pressure makes the powdered metal get sort of fixed in its position and afterward needs double pressure to detach from the die. This ruins the finish of the powder metal parts. Therefore, what every manufacturer of metallurgy parts should consider doing is to make undercuts, cross holes, or any net shape to make it easy for the powder metal part to come out of the die casting with a perfect finish. Another thing that you need to decide on is the use of material. Every material puts a different challenge on you; therefore, choosing the material wisely will help you in getting a high-tensile strength powder metal part that requires no further machining. Like it is said that more rigid materials are easier to deal with. Usually, manufacturers use iron, carbon, and copper mix for powder metallurgy. However, nickel, chromium, vanadium, and some other metals will also prove to be a very good materials for powder metallurgy.

Advantages Of Powder Metallurgy Metal Parts:

The main benefit of powder metallurgy is that it cuts down on the waste of metal to zero as no scraping of metal takes place in this process. Therefore, you will also save on the cost of material, thereby a very cost-effective method for manufacturing metal parts. The other benefit is that this method helps to give the metal parts much-improved strength and firmness. This method also offers opportunities to use a mix of a variety of materials which directly increases the quality of the metal part. This method also helps control the porosity of the parts that are being manufactured. It is also a very beneficial method for making complex design metal parts. Now there is no boundary in making any metal design as the powder metallurgy process can help achieve any design with ease. This method is also very cost-effective as compared to other methods. This method helps to achieve identical designs in manufacturing bulks of metal parts.
