Cell Impact’s proprietary manufacturing technology and methods are primarily aimed at applications featuring embossing. At the core of Cell Impact’s technology is our unit’s high accelerations and velocities that softens the material.
The method, often referred to as adiabatic softening, essentially means that a small portion of a part becomes extremely hot, up to 800 ˚C within a thousand of a second. This allows us to leverage the advantage of that the material gets softer, despite that the softening is taking place non-thermally.
High-velocity impacts in excess of 10 m/s are generally called adiabatic softening, and allow solid metal to be cut, blanked, pierced, embossed or compacted comparatively faster and with quality and product performance outcomes superior to that of conventional methods. This process is conducted cold, meaning that the metallic material is cold before and after it has been formed, blanked, compacted or cut. Energy consumption is lower compared to a conventional process since less force is needed to process the product.
The High Velocity Impact Unit
Cell Impact’s technology is based on a hydraulic piston that can be dramatically accelerated to high-velocity in a very short distance – about the same magnitude of the launching of a missile. This occurs in less than a thousandth of a second and is causing the material to soften.
Cell Impact’s High Velocity Impact Unit can generate speeds of up to 15 meters per second with a high level of repeatability and precision without any changes in impact energy or process dynamics. The greater the impact energy, the higher the temperature. The process results in impacts generating quality incisions, patterns or compacted materials in a fraction of a second, since there is no time for heat energy to be conducted away to the tool or work piece.
The size of the machine and type of tool housing and tool configuration are selected on the basis of the application.
Key Benefits with Cell Impact’s High Velocity Impact Unit
The high-velocity technology is suitable for piercing, embossing and coining of a pattern. The technology can also be used for compaction of metal and graphite powders. In case of compaction, the powder is dynamic and pressed together into a cohesive unit.
The High Velocity Impact Unit and our manufacturing concept offers:
- Comparatively faster cycle times and lower manufacturing cost at higher volumes
- A lubricant-free process which means a cleaner manufacturing environment
- A material softening that requires less force and less energy to perform the required work
- Comparatively less spring back
The process generates an extremely short and powerful spike in temperature, adiabatic softening, enabling comparatively better quality and product design outcomes:
- Increased straining enables more advanced and exact patterns
- Increased green density when compacting
Compared with competing manufacturing approaches the High Velocity Impact Unit offers:
- Comparatively less capital expenditure
- Improved formability that can be used to manufacture more advanced patterns, or to reduce material costs
- A comparatively simple manufacturing method
- Shorter cycle times and greater manufacturing output
