RCL, an Italian manufacturer of machinery in the cardboard, publishing and packaging industry, chose Aventics to supply pneumatic components tailored for its Rotoshaftless 250. The machine is a new 5 colors gravure press with small format, developed under request of Enpoplastic, a customer specialized in the molding of warranty closures for the wine industry.
The Rotoshaftless 250 is suitable for the production of short runs and designed for printing capsules in the enological sector, realized in poly-laminated, PVC and aluminum, suitable for water and solvent based inks. The machine is completely built in electric axis and is equipped with a quick job change system, without requiring the use of carriages and instead equipped with a drying unit with hoods with differentiated high-performance temperatures.
RCL chose the Aventics components to guarantee excellence and reliability, already found in previous applications. The Aventics’ pneumatic cylinders, pressure regulators, single valves and valve islands that have been installed have simplified the construction of the pneumatic system and reduced the components to be purchased, thus limiting the purchase budget. Specifically, in the machine are present the single control valves 5/2 of the LS04-AF series, particularly light and fast, and perfect for applications where is required a close connection on moving parts. Further components, chosen for quality and excellent functionality, have been also high precision pressure regulating valves, electronically controlled, such as proportional ED02 valves and with direct drive such as the PR1-RGP series reducers, suitable for extremely accurate control of printing pressures and tensioning.
