Types of Extrusion Processes
Extrusion can be classified into several types based on the direction of material flow and the working temperature. Below is a comparison table of the different types of extrusion processes:
| Type | Description | Advantages | Disadvantages |
|---|---|---|---|
| Direct Extrusion | Material is pushed through the die in the same direction as the ram. | Simple process, suitable for long products. | High friction, requires more force. |
| Indirect Extrusion | The die remains stationary while the billet and container move together. | Reduced friction, less force required. | Limited to certain shapes, more complex setup. |
| Hydrostatic Extrusion | Uses a pressurized fluid to reduce friction during the extrusion process. | Excellent surface finish, suitable for brittle materials. | Requires specialized equipment and fluids. |
| Impact Extrusion | A metal slug is struck with a punch to shape it into the die. | High efficiency, ideal for thin-walled products. | Limited to softer metals, high compressive force needed. |
| Cold Extrusion | Performed at room temperature, enhancing strength through strain hardening. | Improved surface finish and mechanical properties. | Requires high forces, limited to ductile materials. |
