MPIF Takes a Look at Market Disruptions and Future Forecasts

October 12, 2022

Rodney Brennen

Powder producers continue to respond to the needs of the industry by developing new and improved materials and additives for conventional press and sinter, MIM, and metal AM. Over the past two years, dry lubricants have been in limited supply and high demand, forcing companies to seek alternatives. The demand to improve “value‐added” machining has resulted in new high green strength materials that are suitable for green machining.

2020 Powder Metal Trends

August 1, 2020

20/20 is considered to be perfect vision, but the year 2020 outlook is quite obscure. We can view the current state of the PM industry through short-term, fear-tinted glasses or gain a clearer picture of long-range opportunities. Just like U.S. manufacturing in general, the PM industry has been impacted negatively by the pandemic.

Influence of the Contact Conditions in Cold Rolling on the Density Profile of Powder Metallurgical (PM) Gears

June 1, 2020

Due to production by pressing and sintering, PM gears are porous. Since pores reduce the loaded area and are also probable crack initiators, the porosity determines the strength of the PM component. PM gears can be densified to increase their local density and, therefore, the load-carrying capacity. PM gears are compacted locally since they are mainly loaded directly at the surface. A common process to densify PM gears locally is the cold rolling process. The contact conditions in the cold rolling process determine the density profile and, therefore, the material properties of the PM component. The influence of the contact conditions in cold rolling of PM gears on the resulting density profile is yet to be investigated.
