Propelling the Marine World into the Future

Most of the propellers today are manufactured through a standard casting process such as die casting, gravity casting, squeeze casting. Although the finished product may look good on the outside, when looking on the inside from a C/T photograph or cutting a cross-section of the product to check the integrity after casting, it can reveal many defects such as shrinkage due to these inferior casting methods.

Casting defects do not commonly become and major issue during the initial high-speed rotations of operation, but after a short amount of time the corrosion rate that a propeller is subject to progresses more rapidly and the blades may even break.

KDPropeller has adopted, developed, and refined the world’s first application of low-pressure casting in its propeller manufacturing process thereby avoiding these defects. This process minimizes defects in the alloy structure while applying pressure when the molten alloy inside the furnace is injected into the propeller mold.

This unique process, unlike all other casting methods, ensures a dense molecular structure with precise strength and ductility.
