2. 1 Title: Introduction to Cold Extrusion Forging Process Cold extrusion forging is a metal forming process where a material is forced to flow through a die using compressive force at room temperature. This process is commonly used to produce parts with high precision and complex shapes. Cold extrusion forging is a cost-effective method for mass production of components in industries such as automotive, aerospace, and electronics.

3. 2 Title: Advantages of Cold Extrusion Forging Improved mechanical properties of the material due to cold working. High dimensional accuracy and surface finish of the final product. Reduced material waste and energy consumption compared to hot forging processes.

4. 3 Title: Basic Steps of Cold Extrusion Forging Process Billet preparation: The raw material is cut to the desired length and diameter. Lubrication: The billet is coated with a lubricant to reduce friction during the extrusion process. Extrusion: The billet is placed in a die and subjected to high pressure to force it to flow through the die cavity.

5. 4 Title: Types of Cold Extrusion Forging Forward extrusion: Material is forced to flow in the direction of the punch movement. Backward extrusion: Material flows in the opposite direction of the punch movement. Combination extrusion: Utilizes both forward and backward movements for complex shapes.

6. 5 Title: Process Parameters in Cold Extrusion Forging Pressure: The amount of force applied to the material during extrusion. Temperature: Cold extrusion is performed at room temperature. Lubrication: Ensures smooth material flow and prevents tool wear.

7. 6 Title: Applications of Cold Extrusion Forging Manufacturing of automotive components such as gears, shafts, and bearings. Production of fasteners like bolts, nuts, and rivets. Fabrication of electronic components and precision parts for medical devices.

8. 7 Title: Material Considerations in Cold Extrusion Forging Metals commonly used include aluminum, copper, steel, and titanium. Material properties such as ductility and strength are crucial for successful extrusion. Some materials may require preheating to improve formability during extrusion.

9. 8 Title: Tooling Design for Cold Extrusion Forging Die design plays a crucial role in achieving the desired shape and dimensions of the final product. Proper selection of materials for the die to withstand high pressures and temperatures. Consideration of draft angles and fillet radii to facilitate material flow and reduce tool wear.

10. 9 Title: Quality Control in Cold Extrusion Forging Inspection of the final product for dimensional accuracy and surface defects. Non-destructive testing methods such as ultrasonic testing to ensure material integrity. Continuous monitoring of process parameters to maintain consistency and quality of the parts.

11. 10 Title: Conclusion Cold extrusion forging is a versatile metal forming process that offers high precision and cost-effectiveness. By understanding the basic principles and parameters of cold extrusion, manufacturers can produce complex parts with superior mechanical properties. Continued research and development in materials and tooling technologies will further enhance the capabilities of cold extrusion forging in various industries.
