What will happen whenthere is uneven powder in powder metallurgy press?

Geepro specializes in the production and sale of powder metallurgy press. When the powder in the press is abnormal, what kind of problems will be caused and how do we deal with them? Let geepro explain the details today.

A. There are impurities in the powder, such as paper, waste products, molding products that have not been demoulded in time, the packed powder will be brought back in the push box rollback process.

Treatment: Check the powder before loading the hopper, if it is necessary to sift it and then add it to the hopper. If the product is left in the hopper during the molding process, abnormal traces of the powder can be found when it is returned from the hopper, and stop the machine in time to take out the product.

B. The powder is not dried and the humidity is too high, resulting in the powder caking and poor fluidity of the powder.

Treatment: The powder is returned to the mixing process for drying and sifting.

C. After sifting, the powder has static electricity, which causes the powder to gather, the blanking is not smooth, and the powder filling cavity appears hollow.

Treatment: After sifting the powder, use wire to release the static electricity in the powder, and turn the powder once by hand.

D. Lubricating powder in powder is not mixed evenly.

Treatment: Generally after sifting the powder can be solved.

E. In the process of powder granulation, the size particles are not uniform and the loading weight is not consistent.

Treatment: Granulated powder, if there is too much fine powder inside, can be screened twice with different screening purpose screen, remove fine powder, leaving only 24 mesh ~120 powder.
