Why should vacuum be used in powder metallurgy processing?

Powder metallurgy needs vacuum treatment during processing, so how much do you know about why vacuum is needed? The following is the share of zhongnwei's precision editor.

1： Why do we need vacuum when processing powder metallurgy bearings?

Cause 1: Make up for the small holes left after sintering

Powder metallurgy molding process will be used for small bearings in many fields. After sintering process, small bearings will leave many small holes. Vacuum treatment is to use an oil immersion machine to fill special insulating oil into the small holes of bearings through vacuum.

Cause 2: Vacuum immersion treatment can improve product performance

Vacuum immersion can quickly fill the insulating oil evenly into the small bearing hole, and make the surface of the bearing more smooth, improve the insulation performance, reduce the power consumption of the bearing, reduce the noise of the product in use and control the advantages of high temperature rise, improve the product performance and improve the service life of the product.

To sum up, the reason for vacuum in powder metallurgy processing has been told to you. I hope this article will help you. If you need to know more about powder metallurgy, please come to zhognwei for precise understanding. We will have professionals to answer for you.
