Cold sintering is an innovative manufacturing process that uses a transient solvent and pressure to consolidate polymer powders into a solid mass. Unlike traditional sintering methods that require high temperatures, cold sintering operates at much lower temperatures, making it energy-efficient and suitable for heat-sensitive materials. This process enhances material properties such as thermal and electrical conductivity, strength, and translucency. It is particularly useful for creating specific material porosity and manufacturing items like bearings, jewellery, heat pipes, and shotgun shells. Cold sintering offers a sustainable and efficient alternative to conventional sintering techniques.
