Neodymium based magnets made by sintering are well known. Having high remanence and coercivity, these "strong" magnets can be small. This project will pursue refinement of a newer process involving tightly controlled hot pressing of specially prepared Nd-Fe-B powder. This manufacturing method creates remarkable changes in the nanoscopic crystal structure of the material, producing magnetic properties that are highly appealing for a number of applications, such as electric vehicle drive motors, multiple automotive electrical systems, energy generation and consumer products. Electrification in many products and sectors has raised a demand for such magnets. In addition to their impressive magnetic properties, hot-formed Neodymium magnets have the vital advantage of not requiring heavy rare earth elements such as Terbium and Dysprosium. Eliminating the need for these metals further entrenches supply chain security to the UK, as well as avoiding the environmental concerns regarding mining and refining these elements.Supply chain security and autonomy are vital for providing consistent production capability for domestic manufacturers of high-quality electronics. Hence, for the move to electrification to proceed reliably, domestic large-scale production of these magnets will need to be demonstrated.This project will embed production of these magnets in the UK supply chain by combining the specialised processing and application expertise shared by SG Technologies -- the UK's primary Neodymium magnet manufacturer -- the Magnetic Materials Group (MMG) at the University of Birmingham, and ZF Automotive UK Limited. Collaboratively, the ability to perform this production process at scale will be demonstrated at SG Technologies with the aid of the metallurgical expertise from the MMG to assist.Additionally, with the assistance of HyProMag, the MMG will demonstrate the possibility of utilising recycled magnetic material as raw material for this production process. The one-of-a-kind technology developed here will further seek to decrease the environmental impact of magnet production, reducing waste and provide further independence to the UK supply chain.The unique expertise in press technology at SG Technologies will make possible the production of a bespoke electric, computer-controlled press capable of high-volume manufacturing of net-shaped, hot-formed magnets, pathing a route towards UK industrial production capability. ZF Automotive UK Limited will take this further by evaluating products where these magnets may be suitable in applications, as well as simulating their performance in applications and thorough characterisation of the magnetic properties of the hot-formed magnets produced. Design of future devices and technologies will also be considered in this context.

通过烧结制成的基于霓虹灯的磁铁是众所周知的。这些“坚固”的磁铁具有很高的延迟和胁迫性，可能很小。该项目将对较新的过程进行改进，涉及特别控制的ND-FE-B粉的紧密控制。这种制造方法在材料的纳米晶体结构上产生了显着变化，从而产生了对许多应用，例如电动汽车驱动器，多个汽车电气系统，能源生产和消费产品，它们具有极大的吸引力。 许多产品和扇区的电气化提高了对此类磁铁的需求。除了其令人印象深刻的磁性外，热形成的霓虹磁铁还具有不需要重的稀土元素，例如terbium和dosprosium。消除对这些金属的需求进一步巩固了英国的供应链安全，并避免了有关采矿和完善这些元素的环境问题。供应的链条安全和自治对于为高质量电子产品的家庭制造商提供一致的生产能力至关重要。因此，为了可靠地进行电气化，将需要证明这些磁铁的国内大规模生产。本项目将通过组合SG Technologies共享的专业加工和应用专业知识，将这些磁铁的生产嵌入英国供应链中 - 英国主要的Neododmium Magnet Manufacturer（MMG）在Birming Ham和ZF Unigutot和ZF Univiceot和ZF Unigutoh，以及ZF UNIPATIC。在SG Technologies中，在MMG的冶金专业知识的帮助下，在SG Technologies中进行大规模执行此生产过程的能力将在Additionally上辅助。在Hypromag的协助下，MMG将证明将再生磁性材料作为此生产过程的原材料的可能性。这里开发的一种一种技术将进一步寻求降低磁铁生产的环境影响，减少浪费并为英国供应链提供进一步的独立性。SGTechnologies的新闻技术专业知识将使定制的电动电机，计算机控制的压力机能够生产出净形状的，热型的巨头生产的途径，使工业生产能够促进型号的工业型。 ZF Automotive UK Limited将通过评估这些磁铁可能适用于应用的产品，并模拟其在应用中的性能和彻底表征所产生的热形磁铁的磁性特性。在这种情况下，还将考虑未来设备和技术的设计。
