Bystronic delivers 300th Mobile Bending Cell
Swiss sheet metal specialist , Bystronic , recently delivered its 300th Mobile Bending Cell . The buyer is the toboggan run and slide manufacturer , Josef Wiegand GmbH & Co KG , from Rasdorf in Germany . The smallest bending cell from Bystronic , the Mobile Bending Cell incorporates a ByBend Star 40 or 80 and a bending robot .
The Wiegand company , well known for its toboggan runs , children ’ s slides , event slides and water slides ( delivered internationally ), chose a Mobile Bending Cell with a ByBend Star 80 and a mobile bending robot .
350 employees manufacture the leisure equipment in Rasdorf , partly by hand , for Josef Wiegand GmbH & Co KG . The company has now decided to automate some of its manufacturing processes to be able to respond better and more quickly to customer requests .
“ The Mobile Bending Cell offers an easy entry into automation , especially for small

and medium-sized companies with limited space . This is because the bending solution has a footprint of just around five square metres ( ByBend Star 80 approx . 3.5m ², mobile bending robot approx . 1.8m ²). A bending cell with a permanently installed robot , on the other hand , [ can be ] ten times as large ,” outlined Bystronic .
“ The Mobile Bending Cell works according to the ‘ Plug in & Bend ’ principle . It can be set up in almost any environment , put into operation in five minutes and quickly repositioned , if required . Simply plug it in and start bending !” it added .
Bystronic focuses on automation of the complete material and data flow of the cutting and bending sheet metal process chain . The intelligent connectivity of lasercutting systems and press brakes with innovative automation , software and service solutions is the key to comprehensive digitalisation in the sheet metal industry , it told ISMR .
Bystronic ’ s headquarters are at Niederönz ( Switzerland ). Additional development and production locations are at Sulgen ( Switzerland ); Gotha ( Germany ); Cazzago San Martino and San Giuliano Milanese ( Italy ); Tianjin and Shenzhen ( China ), and Hoffman Estates ( USA ). n

Passivation and pretreatment in a single step
The goal of Henkel Adhesive Technologies ’ latest product innovation was to achieve more sustainability and greater process efficiency in colour coating processes . With its Bonderite M CR 1405 , the surface treatment specialist has developed an RoHS-compliant ( restriction of the use of certain hazardous substances ) agent that provides coils with passivation and pretreatment properties , as well as corrosion resistance , in a single pretreatment step .
The classic treatment of metal surfaces uses two different lines : one for pretreatment and one for passivation . With the conventional process , the parts either go directly to the user or onto the painting line . The rust-preventive ( RP ) oil used before painting must be removed in the subsequent cleaning and rinsing stage . If a passivation coat is applied , a single rinse before the subsequent application of paint is sufficient .
Henkel ’ s new development enables users to substantially shorten their process . Bonderite M CR 1405 can be used as a passivation for bare substrates and pretreatment for painted substrate . After passivation , the coils are either sent directly to the end user or on for painting .
“ Bonderite M CR 1405 has good ‘ recoatability ’ and coils passivated with this product can be used on the colour coating line without a cleaning step and need only be rinsed with hot water to remove any contamination . This results in major savings in energy and water usage , since the cleaner that has now been eliminated is typically used in

large tanks at temperatures of between 60 and 70 degrees Celsius . The absence of chemical cleaning agents also means that wastewater pollution is significantly lower ,” explained Henkel .
This combination is made possible by the newly developed chromium III-based passivation pretreatment , Bonderite M CR 1405 , which combines both processes .
“ Normally , when paint is applied to a passivated coil without subsequent treatments , insufficient paint adhesion and corrosion resistance is the result . Conversely , pretreatment used as passivation usually fails within one day ,” said Gerko Odink , Senior Manager PD Metals EU , Henkel Adhesive Technologies . “ We have an agent here that combines the best of both worlds and is compatible with both chromiumbased and chromium-free primers .”
As this is a chromium IIIbased product , it meets users ’ performance expectations for high corrosion protection while also being RoHScompliant . This directive prohibits the use of hexavalent chromium in Europe .
“ We are closing the gap between legislation and performance by using a bridging technology that meets the requirements for architectural applications , for example ,” outlined Gerko Odink . He confirmed that testing on galvanized and Galvalume substrate shows blank corrosion resistance of more than 96 hours . The salt spray test shows resistance of 800 hours with a chromium primer and 500 hours with a chromium-free primer .
By reducing the number of process steps and the associated energy and water consumption , the new product is in line with Henkel ’ s longstanding commitment to sustainability . n
