The efficiency of the production process of advanced magnetic materials is key to competitiveness and sustainability in modern industry. Advanced magnetic materials are modern materials with enhanced or unique magnetic properties that find applications in cutting-edge technologies, such as renewable energy sources, electromobility, sensors and electronics. In this way, using the Tecnomatix Plant Simulation software reduces costs, increases product quality, and brings products to market faster while also helping to mitigate the environmental impact of production. The use of this software in the development and optimisation of production processes is currently an increasingly important task. The presented article focused on the optimisation of the production process for 320 compacted 3-D samples from advanced magnetic materials, where specific production locations (bottlenecks) were identified and the use of machines and labour was optimised. The research focused on adding value by reducing handling movement and handling times, as well as increasing the production flow of advanced magnetic materials.
