Propeller Manufacturing Process
Foundry
We employ rigorous casting processes that allow us to produce high-quality components tailored to each client's specific needs. Our facilities are equipped with electric induction furnaces and Patternless robotized cells.
Machining
Our advanced machining center features CNC-controlled machines, the hydraulic surfaces are obtained in CNC 5-axis milling machines, and several CNC lathes capable of handling up to 4.3 meters in diameter.
Finishing shop
To ensure smooth surfaces and optimal finishes that enhance both performance and aesthetics, we combine automated and manual work. CNC controlled robots do most of the polishing work, while our skilled workers give the final touch by hand.
Inspection
Every piece we manufacture undergoes a rigorous dimensional control process to meet the most demanding standards in the maritime industry. We have a laboratory available with a spectrometer for chemical analysis and tensile strength machine. We have as well static and dynamic balancing equipment.
