Cold stretching in the metal industry

In cold stretching, metal parts are processed at room temperature or slightly below in order to improve their mechanical properties. The advantage of this process is that the surface structure of the material is retained as far as possible, while the strength and toughness are increased. The use of dry ice opens up additional possibilities here, as the extreme cold of the material gives the metal surfaces a short-term brittleness. This makes it easier to shape the metals without them breaking or cracking.

Optimization of metalworking

The application of dry ice for cold stretching takes place in several steps. First, the metal piece is treated with dry ice, which leads to a significant reduction in temperature. This reduction in temperature increases the material’s malleability, reduces structural stresses and reduces the risk of distortion. Metalworking can then be carried out more precisely and with less effort.

Another relevant aspect of cold stretching with dry ice is the improvement of the material’s surface properties. Treatment with dry ice reduces the surface roughness, which leads to better wettability and corrosion resistance. This is particularly advantageous for applications in the aerospace and automotive industries, where the highest demands are placed on material performance.

Increasing efficiency and improving quality

In practice, the combination of cold stretching and dry ice not only increases the efficiency of production processes, but also significantly improves the quality of the end products. The metal industry benefits from this technology as it offers the opportunity to develop innovative solutions for complex challenges.
