Extrusion is commonly used to make collapsible tubes such as toothpaste tubes, cans usually using soft materials such as aluminum, lead, tin. Usually, a small shot of solid material is placed in the die and is impacted by a ram, which causes cold flow in the material.

Explanation:
Production of Toothpaste Tube:
Toothpaste tubes are typically produced using a process known as hollow backward extrusion.
Hollow Backward Extrusion:
- In this process, a tube-shaped metal blank is placed in a die cavity.
- A punch is then used to apply pressure to the inside of the blank, forcing it to flow backward and take on the shape of the die cavity.
- This results in the formation of a hollow tube with the desired dimensions and features, such as the threaded nozzle for dispensing toothpaste.
Advantages of Hollow Backward Extrusion:
- Allows for the production of tubes with complex shapes and features.
- Provides better control over the dimensions and thickness of the tube.
- Can be used to produce tubes at a high volume with consistent quality.
Conclusion:
Toothpaste tubes are commonly produced using hollow backward extrusion due to its efficiency, precision, and ability to create tubes with specific features.
