What sintering methods are often used in powder metallurgy process

Powder metallurgy bearing is a new material, its research and development plays a very important role, and in the manufacturing process of powder metallurgy bearing, there is an indispensable link, that is, sintering. There is not only one kind of powder metallurgy bearing sintering, but also depends on the feeding mode of powder metallurgy in the production process, which is mainly divided into continuous sintering and intermittent sintering.

What is the difference between powder metallurgy bearings and the two? The author takes you to understand it

The feed for continuous sintering is conveyed by push rod or roller table and mesh belt. In the sintering process of powder metallurgy bearings, it is necessary to prepare corresponding furnaces with several main functions, namely dewaxing, pre sintering, sintering and cooling. In the sintering process, materials must be sintered continuously or steadily at each stage.

The advantages of continuous powder metallurgy bearing sintering are its high efficiency and selectivity for mass production. [/hydrogen/] [/hydrogen/] The efficiency of intermittent sintering is much lower than that of continuous sintering. It is mainly used for single piece small batch production. Put the parts into the sintering furnace, and then preheat, heat and cool the sintering furnace through temperature control. The furnaces for intermittent sintering are usually bell type and box type.
