Aluminum mascara tubes are typically made using a process called extrusion. Here are the basic steps involved:
The first step is to create an aluminum billet, which is a long cylindrical bar of aluminum. The billet is typically made from recycled aluminum, which is melted down and then cast into the shape of a cylinder.
The billet is then heated to a specific temperature and pushed through a die using a hydraulic press. The die is a specially designed shape that will create the desired shape of the mascara tube. As the billet is forced through the die, it takes on the shape of the die and comes out the other side as a long, thin tube.
Once the tube has been extruded, it is cooled and cut to the desired length. The ends are then trimmed and the tube is cleaned to remove any debris or residue.
The tube is then sent to a printing facility where it can be decorated with labels or designs using a printing press.
Finally, the tube is fitted with a cap and any other necessary components, such as a wand or brush, and then filled with mascara.
Overall, the process of making aluminum mascara tubes is relatively straightforward and can be done quickly and efficiently using modern manufacturing techniques.
