Product Description

The YA801250EST series electronic shaft driven rotogravure printing machine is a high printing speed machine to print OPP, BOPP, PET, BOPA, PVC and etc films. Independent double-arms turret type unwind and rewind units can finish automatic cut and splicing without stopping machine. The machine uses servo motor tension control system and every plate cylinder is driven by servo motor for synchronization compensation of register. The parameters are set or modified on a touchscreen (HMI). This machine has hot air recycle system and sealed drying ovens with unique hot air nozzles. The rigidity and stability of the machine is ensured by using high quality materials which are processed on high precision CNC machines. Human oriented design of the machine is easily and conveniently for users to run.
