TECHNOLOGY DESCRIPTION
Current methods for manufacturing complex parts are not fully satisfactory: loss of material, length of process, materials with imperfect performances... Spark Plasma Sintering (SPS) is a rapid densification technique which allows to get materials exhibiting higher performances. Combining this technology with a method for producing complex shapes is today possible.
- Manufacturing process of complex parts to nearest dimensions, so called near net shape
-> Use of a sacrificial material (possibly of different and less expensive kind)
-> Creation of mobile interfaces
-> Evolution of the mobile interface during the densification: support the formation of the part to its final dimensions
- One step process
- Manufacture of several parts in a single matrix
- Fast production of high performances parts
