Metal strip processing
REDEX strip processing plant .
After taking over UNGERER GmbH in 2017 , REDEX Group has acquired strategic patents from BWG GmbH . As a result , it is now able to offer a large portfolio of metal strip processing solutions , from foil to heavy gauge coils .
Aiming to develop new technologies and support metal strip producers worldwide , REDEX Group has also strengthened its R & D by opening an engineering centre in Duisburg .
“ Modern production and assembly facilities in France ( Ferrieres ) and Germany ( Pforzheim ), as well as service centres in China ( Shanghai ) and the USA ( New Jersey ) allows us to offer full service , from engineering to key equipment through
to complete strip processing lines , and from automation or measurement and control systems to spare parts and training ,” it told ISMR .
The portfolio of metal strip processing solutions from REDEX Group includes consulting ; engineering and line modernisation ; complete process lines ( heat treatment , coating , cleaning etc .); finishing lines ( tension levelling , slitting , cut-to-length ); in-line flatness measurement and closed loop control systems , as well as key equipment ( skin-pass mills , flying shears , stacking units , edge trimmers etc .) and tooling ( 20-high mill backing assemblies , leveller cassettes and working rolls ).
REDEX Group is a 70 year-old family owned European group with facilities in Europe , USA , China and India . With more than 100 engineers and 450 employees worldwide and a portfolio of 40 patents , it enjoys a global footprint and offers expertise on key industrial processes . n

The ACCURL GENIUS press brake with Hybrid Servo .
CNC front sheet followers for deep-box bending .
Customised bending
ACCURL CNC Machine Tools ( Anhui ) Co ., LTD , produces CNC machine tools and sheet metal processing equipment . It offers a wide range of precision machines such as press brakes ; laser cutting machines ; shears and CNC punch presses .
“ Our machine tool quality is a result of strong materials , thoughtful design and intuitive controls , along with additional options and add-ons that can be used to modify machines to fit the needs of customers ,” the Chinese sheet metal specialist told ISMR .
Its GENIUS press brake range is fully configurable to customer requirements . The standard press brake range features models with capacities from 40 to 2000 tons . ACCURL also builds bending machinery with different configurations , upon customer request . It described one such example to ISMR .
“ Early in 2020 , we received an enquiry from a Czech customer . He had been looking for one qualified and premium manufacturer to meet his bending requirement for a large box up to 600mm deep . He had watched a few ACCURL press brake videos on YouTube and then contacted us through our website . We explained that our high-end CNC metal fabrication machines are mainly exported to Europe , the United States , Australia etc . and are built according to European CE safety standards and American standards ,” Elvis Dong , ACCURL ’ s deputy general manager , explained .
“ After receiving the customer ’ s workpiece drawings , our engineers carried out pressure analysis , deformation mechanics analysis and simulations using SolidWorks software to validate the bending effect on the workpiece . In the end , we designed a customised pressbrake for this Czech customer .”
The customised version was based on the standard configuration of the GENIUS pressbrake range , which features a Delem DA66T 3D CNC control unit with Profile-T3D offline software ; 4-axis model ( Y1 , Y2 , X , R axes ); CNC crowning compensation ; ECO POWER technology ; a CNC front support follower ( 2 × 180kg ); CE Norms : Lazersafe Systems PCSS
A1 + IRIS and an ACCURL-designed doublesided clamp-holder . ACCURL ’ s Genuis B25110 was specially configured for deep box bending for this customer ( 960mm daylight , 450mm throat and 350mm stroke ).
“ Due to the COVID-19 epidemic , the customer could not personally inspect the machine . We therefore took photos and videos in accordance with the details agreed with the customer . Online videos of the entire bending process ( import of drawings , parameter settings and unfolded bending process ) were all shown to the customer . The customer professed himself very satisfied and accepted the customised press brake ,” added Elvis Dong .
The Hybrid Eco Function on this press brake is a hybrid servo-drive system . Depending upon cycle characteristics and rating , servodrives can offer substantial energy savings to manufacturers .
“ We aim to deliver continuous product innovation to help our customers achieve high performance , with reduced production costs and scrap . Our press brakes , configured to customer requirements , are fast , productive and reliable ,” concluded ACCURL . n
