The MPIF reflects on the state of the North American Powder Metallurgy industry in 2020

The coronavirus (COVID-19) pandemic has meant that the majority of this year’s Powder Metallurgy industry events were cancelled, among them the highlight of the year, the World Congress on Powder Metallurgy & Particulate Materials (WorldPM2020).

This year, it was the turn of the Metal Powder Industries Federation (MPIF) to organise the biennial event, which had been set to take place in Canada in June. Without this gathering of the global PM industry, the MPIF chose to release its yearly presentation on ‘The State of the PM Industry in North America’ via its website. Here we present MPIF President Dean Howard’s overview.

Next-level defect detection with advanced Acoustic Resonance Inspection

Many in the Powder Metallurgy industry have long been familiar with acoustic resonance inspection (ARI), also called resonant frequency (RF) inspection, as a method of non-destructive inspection. In one form or another, ARI has been in use for more than twenty-five years. Although the technology has evolved over time, the last meaningful development was introduced almost twenty years ago.

Now, a significant advancement in ARI technology is reported following the release of SmartTestTM from Advanced Material Solutions. In this article, Peter Miller, the company’s president, provides an overview of the basic principles of ARI, and introduces the benefits of using the SmartTest system for the non-destructive testing of components.

A fully-integrated automated production cell for increased PM productivity

The automated handling systems available to the Powder Metallurgy parts maker can often result in reducing the output of a press, due to multiple control systems from different equipment manufacturers and a lack of full system integration.

To address these issues, Osterwalder AG studied the cost structure and infrastructure of its customers. Based on the findings of this study, the company developed the Smart Press Cell, an integrated approach to part handling in the production of PM parts. Here, Jens Moecke, Osterwalder’s Marketing Manager, explains how the system can improve productivity in a PM facility.

MPIF Powder Metallurgy Design Excellence Awards showcase range of demanding applications

The winners of this year’s Powder Metallurgy Design Excellence Awards competition, sponsored by the Metal Powder Industries Federation (MPIF), were announced through a series of press releases due to the cancellation of the World PM2020 Congress.

The awards included components made by conventional press & sinter Powder Metallurgy, Metal Injection Moulding and metal Additive Manufacturing. Here, we present the conventional ‘press and sinter’ PM components that received either Grand Prizes or Awards of Distinction.

The micro-ingot route: A variant of the PM process that could offer new opportunities for the PM industry

A recently published patent, outlining a proposed method to produce alloyed metallic parts, could result in numerous opportunities for the Powder Metallurgy industry as it competes for new applications in a changing marketplace.

By hot densifying metal powder comprised of atomised particles (micro-ingots), with each particle having a predetermined alloy content, the aim is to form a finished or near net shape highly homogeneous alloyed product, with minimum possible impurities and enhanced dynamic mechanical properties.

The method is said to be applicable to a broad range of alloys and applications. In this article, Harb Nayar, president of TAT Technologies LLC, outlines the thought process behind the patent, as he looks to work with selected partners to further the technology.
