CPP BLADES

Dynamic Castings CPP Blades are reliable in performance bacause of the uniformly enduring quality that has been cast into them. Throughout, they are made to give you service.

In the manufacturing of CPP Blades, there are several distinct steps, each are under with supervision and conscientious study based on practical experience.

RECONDITIONING OF because of the unusual qualities of controllable pitch propeller or variable propeller, replacement of new CPP are very expensive, so we offer reconditioning on Blade and Journal hub such as:

1. • Straightening mis alligned blades @ various radius
2. • Aligning leading and trailing edges, polishing and weight balance
3. • Re-facing CPP blades journal fit on journal hub
4. • Re-conditioning and modification of journal hub assembly, including machining, drilling, tapping and inserting sleeve (same material as mother metal) to fit CPP Blades to journal hub as per approved tolerance.
