Automated tube manufacturing produces tubes faster, more precisely, and more cost-effectively than manual tube processing. This is achieved through the integration of mechanical forming and digital control systems: networked machines, industrial robots, and CNC controls handle bending, cutting, welding, and inspection based on precise CAD data. In this way, automation significantly boosts production efficiency and competitiveness.
What exactly does “automated tube manufacturing” mean?
Automated tube manufacturing refers to the fully automated production and machining of tubes, in which machines, robots, and software work together. The process combines mechanical forming with digital control systems and operates based on precise CAD data rather than manual adjustments.
Because CNC control and automated processes minimize human error, the pipe joints and components are produced with consistent, reproducible quality. In addition, automated systems operate around the clock without fatigue—thereby reducing both staffing requirements and the risk of errors.
How a Production Cell Automates Pipe Manufacturing
A fully automated production cell integrates various machining tools with a handling robot to form a single production unit. This might involve linking several machines and a handling robot together to automatically manufacture various components with different geometries, lengths, and tube diameters.
Depending on the raw material, the tubes are fed into the system from a coil or via a loading table. This is followed by processes such as straightening, cutting, bending, punching, deburring, and tube end finishing. The handling robot transfers the workpieces between the individual processing steps, moving them—for example—from the CNC tube bending machine to the next forming station. In this way, the networked production processes mesh seamlessly without the need for constant manual transfer.
At Schnelldorfer Maschinenbau, PLC and HMI control systems handle the central operation and adjustment of automated welding systems. Depending on the machine, these systems can be used, for example, to store key process parameters, call up programs or recipes, and precisely control recurring processes.
And what is a CNC tube bender?
The CNC tube bending machine shapes tubes according to a programmed bending geometry. It forms the heart of the automated production line and is usually positioned in the process after the cutting or material feeding stages.
The machine features a rotatable bending head that can accommodate multiple bending tools as well as a punching tool. This allows for the production of different bending geometries for tubes of the same diameter without having to completely reconfigure the production process for each variant. The CNC-controlled tube bending machines can therefore process tubes of different diameters with consistent results. They can also be easily integrated into an automated production line.
From the bent tube to the finished component: These are the processing steps involved
Pipe processing is not complete after bending. Pipe manufacturing therefore combines several processes and guides the pipes step by step from cutting to further forming and finally to joining.
The process often begins with cutting the raw material: High-precision cutting methods, such as laser cutting, cut the tube materials cleanly and precisely. The good news: Many modern tube laser systems can process tubes with diameters up to 220 mm. This optimized cutting reduces material waste while simultaneously creating the ideal starting shape for tube end processing.
In this process, the tube ends are, for example, deburred, punched, or perforated, thereby preparing them for their subsequent use. Additional forming steps can also be integrated into an automated system, ensuring that as little manual intervention as possible is required between the individual processing steps.
If individual pipe sections are to be permanently joined together afterward, the joining process follows. Automated welding cells and modern welding robots handle these repetitive welding tasks with high precision, producing exact, reproducible welds. Production robots like these significantly increase efficiency in pipe manufacturing and can be easily integrated into manufacturing processes—with the help of our experts, if desired.
In this way, individual processing steps ultimately come together to form a continuous manufacturing process that does not end until the component is finished.

Frequently asked questions (FAQ)
What are the different methods used to manufacture pipes?
There are two methods used to manufacture pipes: seamless drawing and welding. Seamless pipes are produced by forming them from a solid block, while welded pipes are produced by forming sheet metal or strip stock followed by a welding process.
How are seamless drawn tubes manufactured, in detail?
Seamless drawn tubes are formed from heated solid stock over a mandrel into a hollow shape and then drawn to the desired tube diameter in several forming stages. This process produces tubes completely free of longitudinal welds, making it particularly suitable for high-pressure and high-quality applications.
And what welding processes are used for pipes?
TIG, MIG, plasma, and laser welding are the primary methods used for pipes, and these are increasingly being performed in automated welding cells. Automated welding systems are particularly energy-efficient and low-emission, and—like automated tube manufacturing itself—they maintain consistent quality and processing speed.
In which industries are manufactured rods used?
Manufactured pipes and pipe components are used in numerous industries. These include, for example, the automotive industry, heating, ventilation, and air conditioning (HVAC) systems, mechanical and plant engineering, energy and utility systems, vessel and equipment manufacturing, as well as the food, pharmaceutical, and chemical industries.
