Technical trends in metal-cutting tools: An overview of ongoing innovation in one of PM’s key markets

Cutting tools for applications in metal processing represent one of the primary markets for the Powder Metallurgy industry. Here, PM technology makes it possible to produce cutting tools with complex geometries to near-net shape, a feat not possible using conventional manufacturing methods.

Despite the basic technologies of metal-cutting tools having existed for several decades, tool manufacturers continue to introduce new products which can provide substantial benefits. In this article, Bernard North, North Technical Management, LLC, overviews developments in materials, design and software that are driving innovation in this important sector of PM.

Fatigue data for PM steels: How the world’s largest PM part producer is facing the challenges of data generation and organisation

Data on the material properties of Powder Metallurgy steels, in particular static and cyclic strength data, is crucial for end-users to have confidence in the production of highly loaded applications. Access to such data also enables the effective use of commercial fatigue simulation software. GKN Sinter Metals, the world’s largest producer of structural PM components, has grappled with the multiple challenges associated with generating, storing and retrieving such data.

Markus Schneider, Robert Maassen, Dennis Wawoczny and Christos Radis, GKN Sinter Metals Engineering GmbH, Radevormwald, Germany, share their insight into this ongoing challenge.

Reducing CO2 emissions in the PM industry: A lifecycle analysis of servo-electric versus hydraulic powder presses

There is a global need for action to minimise greenhouse gas emissions and, thus, limit further global warming. Despite its reputation as a technology which is already greener than most, this also holds true in the Powder Metallurgy industry. In recent years, PM companies have found themselves under increasing pressure to improve process sustainability, from their customers as well as regulators.

This pressure is only likely to increase in the near future. Michael Looser and Michael Sollberger, of Switzerland’s Osterwalder AG, explain how the company’s servo-electric powder presses help make PM even more efficient.

Nickel-free steel powders: Paving the way for sustainable Powder Metallurgy

Few sectors of industry remain untouched by the demands of sustainability. The response to climate change has ramped up considerably in most countries, with consumers and regulators alike looking for greater assurance that products have the lowest environmental impact possible, across the value chain. PM is no exception, and increasing numbers of PM projects on sustainability have emerged to meet this need.

The EU’s NEWMAN project is one such effort, seeking to drastically improve PM’s sustainability by minimising nickel content in steel powders. Here, the NEWMAN partners discuss the project’s goals, progress and roadmap to completion.

Euro PM2020: PM functional materials in energy management and magnetic applications

Within the programme of the well-received Euro PM2020 Virtual Congress, held October 5–7, 2020 by the European Powder Metallurgy Association (EPMA), technical sessions showcased the latest studies on the high-temperature properties, corrosion and wear performance of hardmetals produced by Powder Metallurgy.

In this article, Dr David Whittaker provides a summary of each paper presented during this session, highlighting the key findings.

    Powder Metallurgy: The original net-shape production process

    Powder Metallurgy components are relied upon by a wide variety of manufacturing industries, from automotive to power tools, household appliances, chemical engineering, filtration and more.

    The main reason for the technology’s success is its cost-effectiveness at producing high volumes of net-shape components, combined with its ability to allow the manufacture of products that, because of the production processes, simply cannot be manufactured by other methods.

    To discover more about how the technology has revolutionised component production, browse our Introduction to Powder Metallurgy.
