Chinese company Zhejiang Jiuli Hi-Tech Metals reconfirmed its trust in Danieli Breda by ordering a new, 20-MN steel extrusion plant capable of producing seamless stainless-steel pipes with diameters ranging from 33 to 68 mm and wall thicknesses from 3 to 8 mm. This order follows those for a 35-MN steel extrusion press and its upgrading to 42 MN.
Both plants will feature intensive use of robotic solutions for management of tools and the other critical phases of the cycle. Automated control of tool sizes will be implemented using 3D vision systems. The temperature of billets and extruded tubes at press exit also will be monitored and controlled to minimise process parameter fluctuations and collect data for process visualization, post-processing analysis and optimisation. This will allow a high level of process stability and therefore to maintain the highest product quality, with extrusion cycles taking place in less than 60 seconds.
With equipment manufactured at Danieli quality workshops, both plants are expected to be commissioned in 2026.
