Due to superior Project management Brückner and Zhejiang Nanyang Electronic Film Co., Ltd. were able to start their advanced 4.2m BOPP capacitor film line two full weeks earlier than agreed. Straight away the customer was able to produce superior capacitor film in 24h continuous shift operation. The produced film easily meets highest international standards with an thickness profile of 2-sigma < 0.6%.
Within four weeks after startup both guarantee runs (with 6.8 µm and 3.8 µm) were completed, what is another proof for Brückner’s unchallenged reliability in Biaxial Stretching Technology.
Features of the Brückner line
This exceptional performance could only be achieved in this time with a Brückner line that features:
IR scanner for best measurement accuracy especially of thin film (supplier: NDC-Infrared Engineering)
Absolutely precise profile control due the perfect combination of:
High TD-resolution of the infrared measurement (spot size 9mm, compared to approx. 25mm for Pm147)
Brückner`s patented, advanced thickness control system with very narrow die bolt pitch of 10mm
New enhanced software for very precise die bolt mapping
Other line highlights
TDO features a new, maintenance free roller chain system with sprocket-free inlet turnaround.
High speed design
Easy & quick clip and chain maintenance
Brückner`s unique direct drive system for rollers in the pull roll stand and contact roll stand are most accurate, reliable, easy to operate and need zero maintenance.
The motor is directly mounted to the rollers` shafts. No gears, no belts – and therefore no contamination from belts` wear.
Pull roll stand with trend-setting film tension control among all rollers to optimise the setting of the film tension – only possible in combination with direct drive system
display of actual film tension without tension rolls:
active control of film tension
direct input of desired film tension
compensation of disturbances
excellent edge cutting
Pull Roll Stand without nip rolls to avoid surface damages of the film. Even at Corona Rollers air knives across the width are used instead of nips to guarantee no backside treatment.
Superior contact winding system with direct drives for the winding spindles (no gears involved) to achieve optimal winding quality for ultra-thin film: specially designed low bending contact roll – for advanced contact winding of ultra-thin films.
