Spiroide works with the best suppliers, with the capacity to complete all the treatment processes required.

Flank grinding:

The key process for our manufacture is driven by using the latest generation machinery with maximum precision and specific software.

Inspection and quality control:

This phase guarantees compliance according to our client requirements. On request, we can manage and arrange inspections by independent recognized bodies such as BV, Lloyd's, GL, ABS, and DNV.

Cleaning, packing:

On-site, Spiroide has gear cleaning and drying systems and modular packing, which has been adapted to each specific despatch, ensuring protection during transport.

Quality, our goal

Every stage of manufacture undergoes process control, where the dimensions and characteristics of the gear, previously defined by our quality department and the client's requirements, are recorded.

We can also offer our clients external certification by independent bodies such as BV, DNV, LR, GL, and ABS.
