Updated hydraulic system
The company has also considered energy and process efficiency to reduce energy consumption and the carbon footprint . The hydraulic system for the Faccin CNCcontrolled plate rolls has been updated with the latest components . Precise sensors have been included to monitor the hydraulic valves and the signal to correct the required amount of oil for each axis action .
“ This solution , already tested in many machines , is the result of ten years of development and has allowed us to offer the industry a product that is at least 20 / 25 % more efficient than the standard hydraulic packs available in the market . The hydraulic system is an exclusive development by Faccin in close collaboration with a major German manufacturer and is available only upon request ,” explained Boldrini .
For the head-forming line , the Faccin Group has updated the design of the hydraulic system to reach a higher level of efficiency and rebuilt the PLC software to achieve total control of the forming process and reduce plate thinning ( which is extremely important to keep control of the tank weight ).
“ This updated control of the forming process also helps the action of the die impact on the plate targeting , giving better uniformity with simultaneous absolute position control . The typical size of a dishing press to produce road tank ends is 300 up to 400 tons ( when the range is extended to railcar tanks ). For intense production operations , a 600-ton press is the ideal choice to increase the number of blanks / round plates being pressed together in a single stack ,” continued Boldrini .
The Group ’ s wide range of flanging machines includes all types of machine configurations to make dished heads with or without the centre hole . Additionally , the option of a tiltable upper beam ( a useful feature when flanging wide-diameter long cones ) is available .
“ The height of the flanging machine is generally extended to facilitate the loading and unloading of the maximum head diameter and for flanging cones with vertical axis on a specially dedicated tool , working on a rotary platform . Our flanging machines feature
an electric-powered main-rotation system to reduce the energy consumption and to extend the rpms of the main shaft . Obtaining the highest speed achievable is fundamental for the final cosmetic pass to make the outer surface of the dished head very smooth ,” continued Boldrini .
Experienced manufacturers in the trailer tank industry know how important this is since , after painting the surface , defects will be revealed . The Faccin Group ’ s solution negates the need for costly plastering . Plastering also has a negative environmental impact on the tank
Flanging machine . construction .
“ In summary , our updated forming systems reduce the environmental impact of the forming process by cutting unnecessary time and ultimately improving the product quality ,” concluded Boldrini .

A focus on flanging
The final step is the flanging operation , which can be done by cold or warm forming , as in the case of aluminium .
