Toothpaste tube can be produced by backward hollow extrusion also known as impact extrusion.
In impact extrusion, a heavy punch is allowed to fall over the material/billet and the material/billet takes the shape of the die. Collapsible tubes are made by this process. This process is limited to soft and ductile materials.

Hollow backward extrusion is the correct method for producing a toothpaste tube. Let's break down the answer and explain it in detail.
1. Introduction:
Toothpaste tubes are commonly made from aluminum or plastic materials. The process of producing these tubes involves extrusion, which is a manufacturing process where a material is pushed through a die to create a specific shape.
2. Types of extrusion:
There are two main types of extrusion: forward extrusion and backward extrusion. In forward extrusion, the material flows in the same direction as the ram or plunger, while in backward extrusion, the material flows in the opposite direction.
3. Solid vs hollow extrusion:
In solid extrusion, a solid billet or workpiece is used as the starting material, which is then forced through a die to create the desired shape. On the other hand, in hollow extrusion, a hollow starting material, such as a tube or pipe, is used, and the material is pushed through the die to form the desired shape.
4. Why hollow backward extrusion for toothpaste tubes:
Toothpaste tubes require a specific shape with a hollow cavity to hold the toothpaste. This means that the starting material for the extrusion process should also be hollow. Additionally, since the toothpaste tube needs to have a smooth and seamless inner surface, backward extrusion is preferred.
5. Hollow forward extrusion:
Hollow forward extrusion is not suitable for producing toothpaste tubes because the material flows in the same direction as the ram or plunger. This would result in a tube with a seam along its length, which is undesirable for toothpaste packaging.
6. Hollow backward extrusion:
Hollow backward extrusion, on the other hand, allows the material to flow in the opposite direction of the ram or plunger. This creates a seamless tube with a hollow cavity, making it ideal for toothpaste packaging.
In conclusion, the correct method for producing a toothpaste tube is hollow backward extrusion. This process ensures that the tube has a seamless and hollow cavity to hold the toothpaste.
