Burgess-Norton and Amsted Automotive: How a legacy automotive supplier is growing with, not despite, electrification

In early 2021, in response to the rapid rate of change in its automotive customer base, Amsted Industries brought two of its Tier 1 automotive supply business units, Means Industries and Burgess-Norton, together. Combined, they formed a new technology team: Amsted Automotive Group (AAG), combining expertise in advanced metal forming, Powder Metallurgy, and electro-mechanical torque transfer and propulsion system design, and positioning Amsted as a key participant in vehicle electrification.

Bernard North visited Burgess-Norton MFG in Geneva, Illinois, USA, and here reports on the company’s history, facilities and ongoing response to a changing market.

Meeting sustainability demands in PM: High-temperature sintering of nickel- and copper-free powder mixtures for low alloyed PM parts

In recent years, all industries have been challenged by increasingly tough regulations aimed at combatting climate change, fast-moving developments in vehicle electrification, fluctuations in the status and supply of raw materials, and more.

The need to increase process sustainability applies even to already-efficient industries like press and sinter PM, where the production of low alloyed parts faces pressure to increase process efficiency and decrease its reliance on the now-critical alloying materials nickel and copper.

In this article, Dr Vladislav Krushanov and Dr Volker Arnhold explore some of the best options to achieve this.

World PM2022: An overview of the status and trends in the global PM industry

The 2022 World PM Congress and Exhibition brought over 1,000 visitors from the industry to Lyon, France, in October. During the event’s Plenary Session, attendees were given the vital facts and figures on industry trends in Europe, North America and Asia. As the PM market faces unprecedented challenges, these statistics are valuable way to take the pulse of the market during a time of unprecedented challenge.

Here, we present the market statistics given during the session, as well as the recipients of the 2022 EPMA Key Note Paper, PM Thesis, Peter Brewin Poster and Fellowship Awards.

A novel approach for the production of metal powders with tailored chemical compositions: AMAZEMET’s rePowder

Establishing new technologies to produce small quantities of high-quality metal powders with tailored, AM-suitable chemical compositions can accelerate the development of new materials for the AM process. These advances not only benefit the AM industry, but its end-users and metal powder producers that are looking for sustainable materials and atomisation methods.

One such powder production technology is ultrasonic atomisation. In this article, Warsaw University of Technology spin-off AMAZEMET shares how its state-of-the-art rePowder device enables the low-cost, eco-friendly recycling and ultrasonic atomisation of metal materials at the laboratory scale.

Productivity, flexibility, reliability: SACMI’s new press technologies for the changing PM industry

In the last sixty years, Italian press powerhouse SACMI has installed over 15,000 presses for a varied list of applications worldwide and achieved a prominent role as a go-to equipment supplier for the Powder Metallurgy industry. Its MPH line of metal powder presses is a mainstay of the PM market.

Now, as PM faces challenges from vehicle electrification, the urgent need to reduce energy consumption, and the growing digitalisation of manufacturing, SACMI shares with PM Review how it continues to innovate and bring new solutions to the evolving market.

Understanding the thermal properties of metal powders: Characterisation of powders using the Hot Disk technique

The thermal properties of metal powders strongly influence the sintering, final density, and quality of PM parts. Properties such as thermal conductivity and specific heat capacity can be used for quality evaluation of PM components, simulations/modelling, process parameter optimisation and more.

Here, Dr Artem A Trofimov, Orton Ceramic Foundation, evaluates the relatively new Hot Disk Transient Plane Source (TPS) technique for measuring the thermal properties of loose powders and compressed tablets, and discusses its potential for quality control via quick differentiation between powders of different metals and/or particle sizes using thermal property calibration curves.

World PM2022: Views on the potential of Field Assisted Sintering for advanced materials

A technical session at the 2022 World PM Congress, organised by the European Powder Metallurgy Association (EPMA) and held in Lyon, France, October 9-13, 2022, addressed the use of Field Assisted Sintering technology (FAST) for the processing of a range of advanced materials.

FAST or Spark Plasma Sintering (SPS) uses a direct current to directly heat the green part through Joule heating, allowing high heating rates and low processing cycle times, thus offering the possibility to manufacture materials with novel and advanced characteristics.

In this article, Dr David Whittaker reviews the four papers presented on the topic at World PM.
