Gefertec GmbH, Berlin, Germany, will introduce its new generation of metal Additive Manufacturing machines at EMO Hannover 2019, set to run from September 16–21 at Deutsche Messe. The new arc405 uses the company’s 3DMP® process and was produced with the support of minority shareholder EMAG Group, Salach, Germany.
The 3DMP process is based on arc welding technology, using wire feedstock, and is therefore cheaper and faster than powder-based Additive Manufacturing processes. With the arc405’s reportedly increased maturity, the company stated that it expects to expand its position in the market and further establish 3DMP as supplementary to conventional manufacturing processes.
The arc405 also has a larger build space, enabling the production of bigger components. Gefertec stated that an advantage of its cooperation with EMAG Group is their mass production expertise, which is enabling it to meet increasing demand for its arc machines while shortening delivery times.
At Gefertec’s booth at EMO 2019 (Hall 9, Booth K03), a number of case studies from customers and partners who are already using 3DMP will be shared, such as Deutsche Bahn AG’s and Rolf Lenk’s production of a wheelset bearing cover as a high-priority spare part for a freight locomotive. This wheelset bearing cover has now qualified for industry-grade use.
In addition to the new generation of machines, Gefertec will showcase its ARC QM Head, said to feature integrated melt bath control for quality monitoring, during the show. This component allows for the welding process to be monitored and recorded, with all process parameters and video images then available for documentation. Using this quality control, Gefertec stated that the stability of the entire manufacturing process can be demonstrated.
The pre-installed version of the arc405 is expected to become available in March 2020.
