TÜV SÜD qualifies Rosswag as manufacturer of metal powder for additive manufacturing
TÜV SÜD, a technical service corporation catering to the industry, mobility and certification segments tales in charge a certification programme to enable metal-powder manufacturers to prove the quality of their processes.
This programme defines safety requirements specified in Annex I to the EU Pressure Equipment Directive 2014/68/EU in reference to the material manufacturer.
In this vein, the organization has recently announced that they have certified Rosswag as manufacturer of metal powder for additive manufacturing. Apart from manufacturing custom metal powders, the latter supplies rolled rings and open-die forged products with weights of up to 4.5 tonnes per piece.
Thorough monitoring along the value chain
Two years ago, Rosswag launches an in-house metal-powder manufacturing for the qualification of new materials. “The purchase of our own atomising plant made by BluePower Casting Systems GmbH has enabled us to control the entire process chain and massively reduce the time needed for the qualification of new materials“, explains Gregor Graf, Head of Engineering at Rosswag GmbH. “After completing the qualification process, we now have comprehensive data sets comprising metal powder characteristics and PBF process parameters as well as mechanical and technological, chemical and metallographic material properties.”
In the certification process, TÜV SÜD Industrie Service GmbH focused on the processes applied to the manufacturing, testing and qualification of the metal powder at Rosswag and assessed these processes in an extensive on-site audit. “The successful audit result confirms that we have full control of our processes and that our production of metal powders for use in additive manufacturing satisfies very high-quality standards”, emphasises Graf.
According to Head of Product Management in the Plant Safety business unit of TÜV SÜD Industrie Service GmbH Gunther Kuhn, the certification process will be completed within two months.
