The Austrian SME is specialized in deep cryogenic treatments (DCT) of metals and components. With this newly developed multistage process, the temperature is reduced down to minus 185 degrees Celsius and improves material performance and efficiency due to lower process time respectively to conventional methods. Mainly used in the tooling and machining industry, it also has positive impacts on tools and instruments in the audio and music industry.
This particular proceeding developed by the Austrian SME is a multistage 15-hours thermal cycling process, which refines workpieces for cutting, stamping, forming etc. During this repeatable computer-operated (CNC) process workpieces are treated to several cooling and heating loops. This process leads to an improvement of the wear resistance as well as to the reduction of internal material stresses in the respective components. Two factors responsible for the improvement of wear resistance in tool steels are on the one hand the transformation of retained austenite into martensite and on the other hand, the formation of secondary carbides, that will be evenly distributed in the microstructure.
Internal material stresses, generated in the production process, can be reduced due to the slow cooling and heating ramps. Due to the automated procedure, the temperature/time graph is precisely controlled and requires less energy than the standard method. Compared to the standard alternative, the multistage process is environmentally friendly, gives better results and is more efficient.
Fields of application:
Every market with abrasive wear problems, stress relief issues and dimensional stability issues, such as:
• machining industry (cutting tools, drills, mills, reamers, inserts; stamping, punching and forming dies)
• automotive (gears, break discs, engine blocks, cylinder heads, exhaust pipes, (valve) springs)
• aerospace (in addition to all above mentioned tools, aluminum components for stress relief and improved strength)
• agriculture and wood (mower blades, ploughs, wood carving tools, chain cutting tools, cutter blocks)
• food industry (cutting knifes, cutting blades, mixers, extruders, etc.)
• music and audio industry (guitars, strings, brass instruments, vacuum tubes for amplifiers, audio cables, etc.)
• electronics (resistance welding electrodes, etc.)
The company is already on the market and is interested in setting up a subcontracting agreement with manufacturers. Especially Germany, Hungary, Czech Republic, Switzerland, Slovenia, Lithuania and Italy are countries of particular interest. The ideal partner will offer related activities in the field of cutting, stamping and forming tools. Manufacturers could benefit from this cooperation in a way, that their produced tools and compnents have a better material performance, and hence the lifespan of the product is increased. The Austrian company wants to expand to new markets and thus to increase their turnover.
