Introduction
Shear Stress Extrusion (SSE) is a form of metal forming process that uses a combination of heat and pressure to manipulate metal materials into shapes and styles. The process of SSE involves a shear force to press a metal material into a shape, usually a tube. Heat is used to soften the metal material, making it easy to shape and form. While this is primarily used for metal material, it has been extended to plastics, rubbers and other materials.
Working Principle of Shear Stress Extrusion
The main principle of shear stress extrusion is the shear force used to deform the metal material into a desired shape. The shear force is applied through a die or mold, which shapes the metal material. The amount of force used is controlled by the shape of the die, the amount of pressure applied, and the amount of heat used to soften the metal material.
The process of SDS requires the metal to be placed in an area of the die which will cause it to be pressed through the die and emerge in the shape of the designed die. Heat is then applied to soften the material and cause it to flow and become malleable. The result is a desired shape and size.
Advantages of Shear Stress Extrusion
There are several advantages to using SSE. First, it is a highly efficient process that takes very little time to complete. This makes it an ideal choice when time is of the essence. Also, since it is a forming process that requires minimal tooling and setup time, it can save time in the overall process. Furthermore, SSE can produce extremely precise and accurate dimensions.
Additionally, SSE is an economical process. The setup time and cost of tools are low and the process is relatively simple. And finally, SSE is versatile and can be used to create many different shapes.
Disadvantages of Shear Stress Extrusion
Despite its many advantages, SSE does have some disadvantages. The major disadvantage is that it is a manufacturing process that requires significant energy input. This energy input is higher than other metal forming processes and can result in higher costs. Additionally, SSE is generally limited to smaller parts as the large forces required to press the material through the die can be difficult to control. Finally, the material’s mechanical properties may be altered during SSE, leading to reduced performance or quality in the finished product.
Conclusion
Shear Stress Extrusion is a metal forming process that uses a combination of heat and pressure to manipulate metal materials into shapes and styles. This process is highly efficient and cost effective, allowing for precise and accurate results. While it has some drawbacks, such as the high energy requirements, SSE is a viable option for many manufacturing operations.
