Durability tests of 3D printed water-hydraulic proportional directional control valves
Despite the fact that water is rarely used in power-control hydraulics (PCH), advanced technologies such as 3D printing of metal components are opening new possibilities for the wider adoption of water PCH. With metal 3D printing, valve mass can be significantly reduced while improving flow characteristics, thanks to the ability to produce complex internal geometries not achievable with traditional methods.

LEAP – razvoj zaščitne embalaže iz alternativnih lignoceluloznih vlaken
Laboratorij LADISK na Fakulteti za strojništvo Univerze v Ljubljani deluje kot koordinator projekta LEAP, katerega cilj je razvoj naslednje generacije trajnostne funkcionalne em- balaže. Ta vključuje gradnike iz odpadne biomase invazivnih tujerodnih rastlinskih vrst in omogoča izdelavo novih, konstrukcijsko visoko zmogljivih embalažnih rešitev. Projekt je izjemno pomemben, saj se osredotoča na trajnostni prehod v krožno ekonomijo, ki te- melji na biološki razgradljivosti in zmanjšanju porabe deviških materialnih virov, obenem pa obravnava problematiko recikliranja odpadkov tujerodnih rastlinskih vrst.

Connecting Industrial Equipment to a 5G Network
The introduction of 5G technology has started a transformative leap in connectivity, enabling seamless integration between existing and new devices in industrial environments. This connectivity solves some technological challenges of linking IT systems with manufacturing processes and offers greater flexibility, agility and efficiency. In industrial applications, 5G facilitates the remote monitoring of equipment, the optimization of logistical processes and the implementation of predictive maintenance, making it a cor- nerstone of smart manufacturing.
Implementing Laboratory Computerized Systems In Pharmaceutical Industry: Regulatory Compliance
The implementation of computerized systems in pharmaceutical industry must meet the compliance with regulatory requirements, assure high level of data integrity (DI) and product quality. This study reviews European legislation, the European and U.S. pharmacopoeias, and global guidelines, such as GAMP 5 and ALCOA++, to identify the necessary standards and best practices.
Increasing the energy efficiency of industrial hydraulic systems using variable drivetrains
Sustainable development and the Green Deal are very important for preserving the natural environment and improving energy efficiency. This is closely linked to the manufacturers of machinery and equipment, including the manufacturers of hydraulic drives. As part of a public tender, a pilot project was carried out to find better designs for hydraulic drives.
