Comparing the manufacturing process for seamless aluminium tube from Phyllis Lucius's blog

The fact that current aluminum tubes are manufactured using a traditional combined die welding and extrusion process means that weld lines cannot be avoided entirely, particularly after oxidation has occurred in the tube. Using a short round bar in conjunction with a high temperature and slow extrusion process, the finished product is produced by extrusion manufacturing in the first place. Maintaining control over three different temperatures at the same time requires meticulous cleanliness. The aluminum rod, the extrusion tube, and the mold are all included in this price. You can modify both the aging time as well as the internal temperature of the pipe wall depending on the thickness and diameter of the pipe wall being worked on.

Extrusion boxes and cylinders are connected together by a screw in the case of the aluminum tube extruder currently in use. The extrusion box and cylinder are composed of two parts: a cylinder and an extrusion box. When the heated aluminum block is introduced into the extrusion box through the inlet port, and the cylinder is turned on, it causes the extrusion beam to push the aluminum block toward the extrusion die and a high temperature to be generated in the extrusion chamber, which results in the production of the aluminum tube. The plasticity of the aluminum block produced in the state is unrivaled in the manufacturing industry. Aside from that, it is possible to reduce the plasticity of an aluminum block by lowering the operating temperature of the aluminum block. It is possible to force the aluminum block out of the extrusion die by applying force to the pressing pad at a high rate and with sufficient force. This causes plastic to flow out of the extrusion die and to emerge from the extrusion die.

During the extrusion process, it is possible to apply a significant amount of force to an aluminum block while it is in a high-pressure state in the extrusion deformation zone, and the extrusion deformation can be enhanced as a result of the increased force applied. If you want to produce an aluminum tube with the cross-sectional shape and size that you desire, you must apply a significant amount of pressure to the aluminum block during the extrusion process. Because of the complex structure of aluminum blocks with an extrusion effect, which have a high degree of mechanical properties, it is particularly true that the mechanical properties of the metal material are enhanced by the structure of the metal material. The longitudinal (extrusion direction) mechanical properties of products produced by other processing methods that are comparable in size and shape to extruded products are significantly higher than the longitudinal (extrusion direction) mechanical properties of products produced by extrusion. When seamless aluminium tube comes to applications, pressing is extremely adaptable and versatile, and it can be used in a variety of settings.

While still using the same machine, the extrusion die can be changed to produce products in a variety of shapes, sizes, and varieties while maintaining the same quality. A new extrusion die can be installed in as little as a few minutes, saving you time and money. Despite the fact that it requires a significant amount of time, it is extremely effective. On the other hand, significant problems have arisen during the fabrication of some double-layer seamless aluminum tubes, and these have persisted throughout the process. As a result, it is critical that this situation be rectified as soon as is reasonably possible, if at all possible.

The majority of the time, continuous aluminum tube is manufactured through the use of a perforated extrusion process. Comparing the manufacturing process for seamless aluminium tube to that of other materials such as steel and aluminum, the manufacturing process for seamless aluminum tube is relatively strict and fine. This is due to the characteristics of seamless aluminum tube, which include a low specific gravity, ease of processing, and a high degree of mechanical strength.

The manufacturing of seamless aluminum tubes presents a number of challenges that must be overcome in order to produce a finished product of superior quality. The following are some of these challenges:Permission is granted for me to share with you some of the issues that must be addressed during the fabrication of seamless aluminum tubes with a seamless aluminum wall with you. Aspects of my positive practical experiences in this area, which have proven to be extremely fruitful, will also be discussed.

To achieve their final shape, which is typically cylindrical, large seamless aluminum tubes are typically produced through hot extrusion and then subjected to a variety of effective post-processing procedures. Small seamless aluminum tubes can be subjected to a variety of effective treatments after they have been formed by hot extrusion or cold stretching, depending on the application.

Blisters are formed during the extrusion of seamless aluminum tubes, and they are brittle. Alumina hydrate produced during the extrusion process must be extruded continuously, causing the alumina hydrate to become drastically dehydrated and, as a result, blisters to form in the tube. Check that the round aluminum rod for extrusion does not contain rolling cracks and that it is not stored in a humid environment if you want to avoid blistering on seamless aluminum pipe. Another important consideration is to ensure that the cleaning liquid contains at least 30% sodium hydroxide, which is an extremely strict requirement. For seamless aluminum pipe to be free of blistering, it is necessary to avoid rolling cracks in the round aluminum rod that is used for extrusion. In order to maintain control over the amount of aluminum ions present in the cleaning solution, it is necessary to use an aluminum ion control valve.
