Lead, tin, or more commonly drawn aluminum tube has been in use since 1841 and is a type of metal.
As a testament to its adaptability and durability, it is now packaged all over the world, with production in the United States alone exceeding half a billion pieces per year, demonstrating its global reach.

The production of drawn aluminium tube begins with the creation of an aluminum slug, also known as a blank. It is fed into a set of tools in the die, which extrude it after it has been heated. After that, the extrusion press forms a rough tube form of the completed tube form.

Next, trim the tube at both the top and bottom ends so that it is the exact length that was specified. It is at this point that the drawn aluminium tubing becomes threaded, allowing us to screw on the cap. Aluminum becomes work hardened during the extrusion process, and it is then subjected to a process that makes the metal malleable during the subsequent process. This is done at a temperature of approximately 460 degrees centigrade.

In the following step, which is primarily used in the pharmaceutical industry, a spray application of an internal lining is applied to the container. As a result, metal-sensitive products are protected from exposure to aluminum by forming a barrier between the aluminum and the pharmaceutical or other product to be packaged.

If the tube has not been internally coated, it will skip the internal lining step and proceed to the next step, which is the coater rolling a base coat onto the tube, which is the final step. The purpose of this coat is to prepare the tube for the application of offset printing in the future. The base coat is then dried and returned to a printing machine, where it is printed with the colors and copy specified by the customer in the first place. You can see all of the tubes that have been detailed for the various customers who have requested different types of embellishment.

Tubes for some products are required to have a fold sealant applied to the fold end of the drawn aluminium tubing, which acts as a barrier to prevent product seepage from the fold end. When it comes to the production of drawn aluminum tubes, the capping operation is the last step to complete. And, once again, the types of styles and caps that customers prefer are usually dictated by them. Cap materials are primarily composed of four different types of materials: polypropylene, high, medium, and low density polyethylene, as well as a combination of these materials.

Once the tubes have been thoroughly inspected, they are packaged in boxes and loaded into cartons or on skids for final shipment to the customer.
