Blogs The Working Process, Difference, Origins About Seamless Aluminium Tube

The processing technology of seamless aluminium tube is more complex and the cost is higher, so the price of seamless aluminum tube is higher. Generally, the slotted aluminum tube is extruded aluminum tube, which has fast production process, easy cost control and cheaper price. However, the purpose of slotted aluminum tube and seamless aluminum tube is different, and the pressure of seamless aluminum tube is better than that of slotted aluminum tube, and the quality of seamless tube is more uniform, The chemical composition of welded pipe in the weld will have a small amount of burning loss, so the mechanical properties are slightly poor, but not very different. If it is used for bending, seamless pipe is recommended. Welded pipe is easy to crack. If the bending radius is larger, it's OK. Today, we are going to tell you the working process, difference, origins about seamless aluminium tube.

Process for Producing Seamless Aluminum Tube
Seamless aluminum tubes are manufactured via the process of piercing, while conventional aluminum tubes are often extruded through the process of a combination die. The short rod, high temperature, slow speed extrusion process is used in the manufacture of aluminum alloy seamless tubes, with special attention paid to controlling the "three temperatures," maintaining a clean aluminum rod extrusion cylinder, and maintaining a temperature and aging time that are adjusted according to the wall thickness and diameter.

This is the distinction between a Seamless Tube and a Slit Tube.
It is possible to manufacture a tube without any welding seams by using seamless tube manufacturing techniques. A seamless tube is also referred to as a seamless pipe in certain cases. It is distinct from the main slit tube in the following ways:

The of Seamless Aluminum Tubing
As a testament to its adaptability and durability, it is currently packed all over the globe, with manufacturing in the United States alone exceeding half a billion pieces per year, demonstrating its global reach. The production of aluminum tubes begins with the creation of an aluminum slug, also known as a blank. It is fed into a series of tools in the die, which extrude it once it has been heated. After that, the extrusion press produces a rough tube shape of the final tube form.

Next, cut the tube at both the top and bottom ends so that it is the exact length that was required. It is at this moment that the tube becomes threaded, allowing us to screw on the cap. Aluminum gets work hardened during the extrusion process, and it is then subjected to a procedure that renders the metal flexible during the subsequent phase. This is done at a temperature of about 460 degrees centigrade.

In the next phase, which is mainly utilized in the pharmaceutical sector, a spray application of an interior lining is applied to the container. As a result, metal-sensitive goods are protected from exposure to aluminum by forming a barrier between the aluminum and the pharmaceutical or other product to be packed.

If the tube has not been internally coated, it will skip the internal lining phase and go to the following step, which is the coater rolling a base coat onto the tube, which is the last 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 chosen by the client in the first place. You can see all of the tubes that have been detailed for the many clients who have requested different kinds of embellishment.

Tubes for certain goods are required to have a fold sealant applied to the fold end of the tube, which serves as a barrier to prevent product seepage from the fold end. When it comes to the manufacturing of aluminum tubes, the capping operation is the last stage to complete. And, once again, the kinds of designs and caps that consumers want are usually dictated by them. Cap materials are mostly composed of four distinct types of materials: polypropylene, high, medium, and low density polyethylene, as well as a combination of these materials.

Once the tubes have been thoroughly examined, they are packaged in boxes and put onto cartons or on skids for final shipping to the client.
