The potential for Industry 4.0 and IoT to monitor and improve powder compaction
The influence of Industry 4.0 can be found in many facets of industrial production and there are very few areas which do not benefit from the application of the Internet of Things, be that in research and development, manufacturing, aftersales or service.
As a result, press manufacturer DORST Technologies recently started to implement IoT practice within its own operations, while in parallel developing smart software for use in its products. Here, Lutz Lackner discusses the implementation of Industry 4.0 and the Internet of Things in powder compaction technology.

Osterwalder: taking a new approach to tooling changeover on multi-level presses
Conventionally, tooling changeover on multi-level presses has been done either by using large, costly full die-set changeover systems, or by interchanging tooling and tool holders manually inside the press.
In this article, Osterwalder’s Stefan Haltner, Michael Sollberger and Alex Wehrli introduce what they describe as a revolutionary new approach to tooling changeover. Using a cartridge system with automatic mechanical coupling combines the advantages of traditional die-set changeover systems with the flexibility and low infrastructure and investment costs of manual tool changes.

Understanding the differences in particle size distribution methods for fine metal powders
In any PM process, the size and shape of the metal powder particles used will have an influence on the properties of the part. However, not all particles are the same size in a given sample of metal powder.
The variation in this range of powder sizes is reported as particle size distribution, and among the methods used to measure this, it is often the case that different systems give different results.
Here, Tom Williamson and John Dunkley of Atomising Systems Ltd, highlight the differences in results from the main methods used to measure narrow-cut, fine metal powders.

Euro PM2019: Novel process developments highlight new opportunities for PM
A technical session at the Euro PM2019 Congress, organised by the European Powder Metallurgy Association (EPMA) and held in Maastricht, October 13-16, 2019, focused on a number of novel process developments in the wider field of Powder Metallurgy.
In this report, Dr David Whittaker provides an overview of three papers, including a look at the use of Spark Plasma sintering in the manufacture of aluminium profiles, the use of Additive Manufacturing in the production of soft magnetic components and a new method of inert gas atomisation.
