PARTNERSHIP FORMED FOR THE CONSTRUCTION OF TOOLS USING ADDITIVE MANUFACTURING
Spritzguss + Formenbau Bergmann, based in Northern Germany, has purchased its first metal additive manufacturing (AM) system, an Eosint M 280 from EOS, and has also become a service provider to the supplier. The partnership will enable the companies to take control of the full process chain of producing tools, and also demonstrates how AM is becoming a valuable technology in the tool construction industry. Bergmann designs and
produces injection mould tools and produces high-grade plastic components using more than 70 injection moulding machines. The purchase of the AM machine enables the company to produce tool inserts, such as cores and slides, as well as prototypes directly from metal. The system is based on the DMLS (direct metal laser sintering) process, which builds components layer by layer based on 3D CAD data. Constant monitoring maximises the quality and repeatability of components. Complex
geometries can be achieved, such as freeform surfaces, fins and cooling channels. In particular, it is possible to create conformal cooling channels using DMLS, which reduce moulding cycle times and improve the quality of the plastic components produced. The material most commonly employed in tool construction is EOS MaragingSteel MS1. Augustin Niavas, business

innovative technologies. The fact that Bergmann has chosen EOS technology reflects the level of maturity that additive manufacturing has now attained. Together, we are able to cover the entire process chain, from the engineering design stage of the tool to the finished plastic component. ‘From this position
we will continue to jointly support customer projects in the future and develop the market for additive manufacturing in tool construction.’ André Gerbert,
assistant to the senior management at Spritzguss + Formenbau Bergmann, added that with the AM system, the company can not only make tools on the premises, but can, ‘now also perform contract work for our customers, based on this new manufacturing technique. ‘It means that we are already

manufacturing enables conformal cooling of tool cores, we can produce a tool that is 50 per cent better in terms of functionality.’
