Project on modelling of springback after cold die compaction

October 9, 2019

A new collaborative project has been announced that will aim to establish a model for prediction of springback following cold die compaction in the Powder Metallurgy process. To be coordinated by OCSynergies, along with the University of Trento and the Polytechnical Institute of Grenoble, the project is expected to last twelve months.

The Modelling of Springback after Cold Die Compaction (MoSC) project aims to investigate the expansion of a green part that occurs during its ejection from the die cavity, referred to as springback, both experimentally and theoretically. OCSynergies states that one of the objectives of the project is the demonstration that springback may be accurately predicted.

It is suggested that two different powders will be used for the purpose of the project: an iron-based alloy and a WC-Co alloy. A model based on the stress/strain relationships in non-linear and anisotropic elasticity will be developed for a simple geometry and validated through experiments using an industrial hydraulic press.

The MoSC project intends to be the starting point for further investigations in this field to be developed with the project partners.

The total budget of the project is reported to be €32,000, with fees shared by a minimum of four funding participants. Those interested in joining the MoSC project are invited to contact Dr Olivier Coube [email protected].

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.
