Introduction
Liquid forging is a process where a workpiece is formed by direct action of the fluid media. As such, it does not involve a distinct die or punch like die forging, consequently allowing for the production of parts having enough complexity to perform special functions. Such parts are created from a continuous solid phase or from a continuously liquefied phase, that is, from a liquid material that never completely solidifies. Furthermore, form-stabilizing metals like titanium are utilized to construct intricate geometries in liquid forging, resulting in a large variety of end products.
However, certain defects may arise during the liquid forging process. Some of these defects include porosity, inconsistency in wall thickness, trapped gas, and trapped liquids. These defects can affect the performance and function of the final product and therefore, the prevention of these defects is paramount in order to ensure the quality of the components produced.
In order to minimize the occurrence of defects in liquid forging, it is necessary to implement cold wall containment technology. This technology utilizes high-pressure and/or low temperature in order to create a contained area between two walls, thus separating the hammer and the workpiece by a vacuum or low-temperature wall. In this way, a contained area is created in which liquefied material flows, ensuring that no unwanted gases or liquids enter or exit the contained area. As a result, this cold wall containment technology prevents liquid from entering or exiting the contained area, thus eliminating some of the potential defects in liquid forging.
The use of this technology thus not only prevents defects, but also increases the efficiency and accuracy of the process. It also minimizes the risk of the material losing its properties due to external contaminants, such as those present in the atmosphere. Additionally, due to the rapid solidification of the metal, there is a reduction in porosity and a higher degree of consistency in wall thickness.
Conclusion
In conclusion, it can be seen that in order to ensure the quality and performance of components created through liquid forging, cold wall containment technology should be implemented. This technology creates a contained area in which the metal flows, thus preventing contamination from entering or exiting the contained area and eliminating some of the potential defects associated with liquid forging. Furthermore, it also increases the efficiency and accuracy of the process and minimizes the risk of the material losing its properties due to external contaminants.
