What are the disadvantages of powder metallurgy process? Today let ZCMIM powder metallurgy manufacturer to explain it to you!

1) the inside of the product has a total pore;

(2) the strength of ordinary powder metallurgy products is lower than that of the corresponding forging or casting (about low 20%~30%);

3) due to the forming process of powder flow is far less than the liquid metal, so the product structure and shape of a certain limit;

4) the pressure needed to press forming is high, so the products are limited by the ability of the pressing equipment;
