Hydraulic Cylinders

Since 1996, we have been designing and producing hydraulic cylinders and pistons for major manufacturers of aerial platforms and lifting equipment, logistics equipment, waste collection and handling machinery, earthmoving and agricultural machinery.

Every day we work together with our customers, give them advice and investigate their needs in order to create customised hydraulic cylinders and tailor services for each of them.

We can participate in the design of the cylinder from the beginning, or develop it from your own design. We adapt to you and your needs.

Know how and production technologies

The enhancement and growth of each internal competence is one of the strategic pillars of the quality of our products and translates into a structured training plan at all levels of the company organization chart.

This happens in parallel with the continuous development and customisation of our production facilities, which, combined with our in-depth knowledge of engineering, allows us to build complex and extremely specific hydraulic cylinders with maximum responsiveness and adaptability to market requirements.

Cylinder washing

We consider cleanliness of components and finished hydraulic cylinders to be extremely important to ensure product quality, functionality and reliability over time.

Over the years we have in fact developed an increasingly structured washing department, where all hydraulic cylinders undergo at least two separate washing cycles during the production process: before welding and before assembly. On request or where the project or application requires it, the washing steps are increased and intensified along the process.

Excellent weldings

Hydraulic cylinders weldings processes are handled in-house, like every other production step.is handled in-house, like every other production step.

Welding is the heart of our production process and is organized in four distinct departments, each specialized in the processes managed internally, both for plants and for the skills of the welders.

90% of the welding processes are performed on latest generation robotic islands, which guarantee very high machining precision. We also have a team dedicated to MAG welding and TIG welding for the most delicate and complex processes, which require experience and special attention.

All weldings are performed by qualified operators UNI EN ISO 9606 and 14732 strictly following the UNI EN 15607 and 15614 standards.
