Description
HUS Ltd. is a Bulgarian large enterprise operating in the sectors of wholesale of hardware, plumbing and heating equipment and supplies, manufacturing of tubes, pipes, hollow profiles and related fittings, of steel and manufacturing of other fabricated metal products.
The implementation of a technology, specifically a roller bending line, marks a significant stride in the production of electric welded products. Notably, this innovative approach employs a single set of working rollers for forming and calibrating profiles across various sizes. Although the welding process for sizes 80x80-200x200 mm/t3-10mm has been successfully incorporated through a recent project funded under the OP "Innovation and Competitiveness," the introduction of this technology remains novel on a national scale.
The key feature of this modern technology lies in its adaptability, where a set of working rollers is manipulated by servomotors and an electronic system to ensure precise movement and positioning. This setup facilitates rapid adjustments between different sizes, enabling the development of new profiles and sizes upon request, with a remarkable increment precision of 5 mm.
This approach allows for heightened production speeds in tube manufacturing. Unlike conventional methods that require changing roller systems for each tube size, the new machine, specifically the Line for direct forming of tubes for sizes 40x40-80x80/t3-6mm, can produce the entire range of tubes with a single roller system. This computerized system not only enhances product precision but also eliminates the need for purchasing calibration and forming profiles for each tube size, resulting in cost efficiency and increased productivity. The technology not only positions the company at the forefront of industry standards but also sets a benchmark for the nation, showcasing the potential for streamlined and efficient tube production processes.
