Elbow fitting forming machines

TTEngineering offers a comprehensive range of elbow fitting forming machines engineered to produce high-precision, top-quality elbows for HVAC, ventilation, and chimney systems. These components are essential for introducing directional changes in ductwork and piping layouts, enabling smooth airflow, optimal energy efficiency, and safe exhaust gas management.

The machines are designed to handle a wide range of diameters, wall thicknesses, and angle configurations, providing flexibility and reliability to meet a variety of production requirements.

PCS & SCS

The PCS model is designed to shape elbow segments in semi-automatic mode, making it ideal for small to medium production batches. Its simplicity and reliability make it well-suited for workshops requiring flexible yet controlled manufacturing of curved duct components. The SCS machine is dedicated to welding the shaped segments using a double-torch TIG system, delivering strong, consistent seams with excellent repeatability. This setup ensures structural integrity and leak-proof joints, which are essential for high-quality ductwork and exhaust systems.

Together, these solutions are particularly effective for producing standard HVAC elbows, ventilation transitions, and chimney connectors, where precise angles and robust mechanical performance are critical. Please note that tooling changes are required when switching between different diameters or bend angles, ensuring proper adaptation to the desired geometry.

PS, SLS, and D-SLS

The PS profiling machine is designed to form male and female edges with high precision using a dual-roller system, ensuring perfect fit and alignment for subsequent welding operations.

The SLS model executes laser overlap welding on an expander base, offering a highly efficient and adaptable process. It enables rapid diameter and angle changes without the need for tooling adjustments, reducing downtime and improving flexibility across production batches.

The advanced D-SLS version features a double rotating spindle that supports continuous production: while one segment is being welded, the next is simultaneously prepared. This setup effectively doubles productivity, making it an excellent choice for high-throughput environments.

Together, these models are ideal for manufacturing a wide variety of elbows, including complex, multi-segment designs used in high-performance HVAC systems and custom chimney solutions, where precise directional flow control and structural integrity are critical.

SLS & SLC Tandem

This combined system integrates two specialized working heads — one dedicated to elbows (SLS) and the other to T-fittings (SLC) — both operating with a shared fiber laser welding unit that moves between stations.

This intelligent configuration allows manufacturers to handle multiple product types within a single compact system, significantly maximizing output and reducing floor space requirements. It is especially well-suited for production environments focused on large HVAC distribution networks and industrial exhaust systems, where both elbows and T-branches are essential components.

By consolidating welding capabilities into a unified platform, this solution provides:
- Higher throughput with minimized machine idle time
- Flexible manufacturing without duplicating equipment
- Optimized workflow and reduced setup complexity

BG-AG articulated elbow machines

The BG machine forms the ends of elbow segments with high precision, while the AG unit assembles them without the need for heating, creating articulated, swiveling elbows that can be manually adjusted to different angles during installation. This system is particularly suitable for applications that require on-site adaptability, such as tight mechanical rooms, complex ventilation routes, or specialized exhaust systems, where rigid connections are not practical. By allowing flexible angular adjustment while maintaining mechanical strength and sealing integrity, the BG + AG system offers a smart and efficient solution for non-standard HVAC and industrial ducting installations.

AK0 robotic assembly station

The AK0 is a fully electric, robot-assisted assembly station designed for the production of elbows without the use of heat. It integrates two specialized cells: one dedicated to edge shaping, and the other capable of assembling up to four segments simultaneously. This configuration ensures high productivity and precise alignment of components throughout the cycle.

Diameter changes are quick and efficient, requiring only the replacement of clamps and seats, enabling fast transitions between production batches with minimal setup time. Fully compliant with European safety standards, the AK0 is the ideal solution for automated, high-volume production of elbows for HVAC systems and chimney applications, where operator safety, repeatability, and consistent quality are critical.

With its complete range of elbow fitting forming machines, TTEngineering supports manufacturers in delivering precise, durable, and high-quality elbows for ventilation ducts, climate control systems, and exhaust lines. Every solution is engineered to maximize production flexibility, reduce downtime, and ensure long-term performance reliability, making TTEngineering machines an essential asset for modern sheet metal and metalworking operations.
