Household, infrastructure or industry: steel is an integral part of our lives. Modern steel materials only enable the production of many high-performance products in conjunction with advanced manufacturing technologies. For example, pressure rolling is used to manufacture stainless steel components for centrifuge or jet engines. A so-called metastable austenitic steel can be used to influence not only the external shape but also the properties of the metal through phase change.
Set component properties in a spatially resolved manner
The scientists at the University of Paderborn, the Technical University of Dortmund and the Fraunhofer Institute for Design Technology Mechatronics IEM are working on an intelligent pressure rolling process, with which manufacturers can precisely adjust the properties of their future components in a spatially resolved manner and thereby integrate valuable additional functions. For example, component states and processes can be monitored, or components can be identified clearly and tamper-proof.
Advantages for the manufacturing process
- Resource- saving : Forming processes manufacture parts without removing valuable material, such as B. happens during milling. Furthermore, the intelligent or controlled pressure rolling process has an influence on physical or mechanical properties such as B. the strength or hardness of the steel. The functionality is improved and manufacturers can save material or use it more specifically.
- Cost-effective: Until now, comparable functionality has been possible - if at all - through complex and expensive reworking or the use of additional components. Manufacturing within a control loop also makes it possible to improve component quality and reduce scrap.
Advantages for the finished steel component
Intelligent, tamper-proof steel components: With the intelligent pressure rollers, for example, a magnetic barcode can be integrated into the steel component. This externally invisible, clearly identifiable code enables counterfeit-proof products to be manufactured.
The project "Property-based control of hardening and phase transformation processes when pressing and pressure rolling metastable austenites" is funded by the German Research Foundation (DFG) with around 450,000 euros for an initial period of two years and is part of the priority program "Property-controlled forming processes" of the DFG. It supports a total of eleven research alliances with the aim of researching the scientific basis of the process-integrated property control of forming processes and to test and validate new approaches to property control.
The lubricant manufacturer Klueber Lubrication keeps struggling with the problem of counterfeiting, especially in China. Now the manufacturer has launched an app to protect consumers from this
Printer manufacturer Leibinger has developed a security ink that is intended to make it difficult for counterfeiters to do business. It is suitable for use in the Jet 3 up PI inkjet printer, which identifies plastic, cardboard and glass product packaging with information such as best before date and batch number. Read here how retailers and consumers can protect themselves against counterfeit products
With additional modules, Siemens is expanding its Sitop PSU8600 power supply system to provide an uninterruptible direct current (DC) power supply. The new module uses the energy stored in the battery modules to supply the system with power in the event of a power failure. This extends the bridging time of the buffer modules up to the hour range
The Rulmeca IP66 / / 69plus drum motors have been Ecolab certified. This gives the motors an independent record of their stability against aggressive cleaning agents and processes
Icotek has two new products in its portfolio: on the one hand, divisible brush strips that are intended to protect against dust and dirt when inserting cables, and on the other hand, the EMC Servicebox Multi. In the box there is a selection of commonly used shield clamps. The range was expanded to include new multi-shield clamps for different types of installation
