Europe's annual powder metallurgy congress and exhibition is set to feature a world class technical program and exhibition on powder metallurgical supply chain.
Innovative glass heating components via 2C injection molding
Glass-powder injection molding is an alternative powder-technological route to the conventional production methods for glass components, which are mostly melt-based. It allows the production of large-size glass components with complex geometry, microstructured surfaces and sharp edges – without the need for expensive grinding or etching processes. Depending on the graphite content, their conductivity lies between 300 and 1 Ωcm. The homogeneous temperature distribution was detected in infrared tests. In contrast to conventional metal-based components for heating applications, the glass components are significantly more compact and cost-effective. Heatable nozzles and crucibles are shown.
Cost-effectiveness despite the use of diamonds
Due to its high hardness and chemical resistance, diamond is used in cutting tools or stone drills. Up to now, the high production costs for the high-pressure process limit the application possibilities of this material. Researchers at IKTS have now succeeded in the pressure-free production of complex-shaped diamond-ceramic composites. The materials substitution of the expensive diamond by ceramics with comparable properties results in a significant reduction of raw material and, thus, in cost savings. These robust and extremely wear-resistant composites provide manufacturers with the greatest flexibility regarding component size and enable previously excluded application fields. Shown are tubes with an inner diamond-ceramic coating and an extreme wear resistance.
3D printing with ceramics and hardmetals
Fraunhofer IKTS has been using AM methods for ceramic components since the 1990s and was a founding member of the Fraunhofer Additive Manufacturing Alliance, which was established in 1998. Today, Fraunhofer IKTS offers complete AM solutions ranging from powder and suspension/feedstock development and production method selection to functionalization and quality control of novel parts and systems. A wide range of materials – oxide and non-oxide ceramics as well as glass, hardmetals, and metals – can be processed in powder form by 3D printing. Shown are components for microreaction technology or toolmaking with highly complex structures, such as wire drawing nozzles with integrated cooling channel.
