FEATURES
Design innovations
BOBST is continually innovating and the VISION K5 is no exception, the machine incorporates a Ø 600 mm coating drum providing the largest coating window in the industry that increases aluminium collection efficiency by 16% resulting in less consumables, an extended boat life and a 10-15% energy reduction. It also provides better film cooling due to the increased surface area of the drum; additional cooling is also given by the 2-zone gas wedge which provides better conduction of heat between the substrate and the drum which is important for heat sensitive films such as CPP and LDPE.
High productivity
The powerful, robust evaporation source with a staggered ceramic boat arrangement provides excellent coating uniformity. It also incorporates easy access to clean the boats and aluminium spools mounted on a removable trolley for easy changing; the full width viewing windows give an improved view of the source and the metallization process.
The VISION K5 pumping group is robust and has a compact design with shorter pipe lengths giving the lowest footprint in the industry; it comprises of dry rotary screw pumps with a consistently high vacuum performance, booster pumps that operate at double the normal speed for maximum efficiency and floor mounted diffusion pumps located underneath the evaporation zone eliminating the risk for backstreaming of oil on to the film.
Energy saving and waste reduction
The K5 VISION incorporates the BOBST ECO Mode which reduces energy consumption by up to 50% during stand-by, only delivering energy and cooling water when needed, this results in a reduced carbon footprint and significant savings in production costs.
Metallizing
Largest coating window in the industry which along with the new Ø 600mm drum improves aluminium collection efficiency by up to 16%.
Improved winding
The renowned BOBST winding mechanism incorporates a 6 drive system giving 3 independent tension control zones. It provides low tension winding with adjustable bowed rollers to produce a virtually wrinkle-free metallization process and an optional pre-drum vari bow for better handling of thinner substrates.The VISION K5 can handle a wide range of substrates including thin gauge films and enables quick changeover of different film types making it the ideal machine for converters. It is also able to handle heat sensitive films such as CPP and PE which makes it perfect for film producers of these thermally sensitive materials.
