Powder Injection Molding for large scale tungsten alloys parts

Developed at KIT IAM-WK, this technology and know-how consist in metal or ceramic parts manufacturing via Powder Injection Molding and include the whole process chain (development, design and fabrication of a PIM tool, filling simulation, tailored feedstock preparation, injection molding, debinding and sintering. Manufacturing materials with high melting points, such as tungsten or doped (with oxides or carbides) tungsten materials with near-net shape precision and in medium to high volumes is a technology of interest for fusion, especially for plasma-facing material (for example Langmuir probes for the WEST project have been produced via PIM). Besides, this technology could find promising applications in solar ovens, power units but also for cost effective mass production of Carbide tools, electrodes, jewellery, turbine blades or in sports accessories: e.g. arrowheads (archery, darts).
