Marine Propellers Quality Control
Design Design engineers of ZF Marine work closely with the customers
and provide full technical support and advice. This service also extends
outside the offices to our experienced field technicians. Throughout
the project phase, design phase and after sales, ZF Marine offers
excellent customer support.
Casting
High quality bronze alloys, carefully chosen with the exact
composition to meet Classification Society requirements, are used
for casting ZF Marine propellers. The chemical composition and physical
properties are precisely controlled and tested for each cast.
CAD System The Computer Aided Design system ensures every propeller is
designed for optimum performance. This leading edge software permits
more selection and flexibility to meet all customers’ requirements.
CAM System The Computer Aided Manufacturing systems generate a precise
cutting tool path for propeller machining. Every detail of the manufacturing
process is simulated and checked before cutting commences.
NC Cutting Numerical Control machining of propeller blades ensures high
precision blade section geometry and the 4-axis machine center system
is integrated with the CAD – CAM software. This leading edge
technology production assures propeller manufacture to the highest
geometrical tolerances required by the ISO R484 Class S standard.
New Series Development ZF Marine also has joint venture programs with various research
establishments to develop advanced technology propulsion system. Latest
research includes a new surface – piercing propeller and new-foil
section series propeller with excellent low cavitation characteristics.
Quality Control- Accuracy means efficiency and reliability
Strength Test ZF Marine continuously checks for the best quality casting
in propellers. The well equipped laboratories precisely control the
physical and this experience leads to continuous improvement of quality.
Dynamic Test All propellers are dynamically balanced to ensure smooth operation.
This dynamic balancing considerably reduces noise and vibration in
high – speed vessels.

of Our Customers!
I just wanted to send you a quick note to let you know the results of my
new ZF wheel. As you know this is my 3rd boat I have replaced with ZF wheels.
The past boats I have gained between 1 and 1.5 knots. The last change over
was aboard the newest "waterman" a 57 foot custom carolina sportfish
with a single 2100 RPM , 1000 h.p 3412 cat. My previous wheel ( High Torque
31x32) was replaced with a 32x32 ZF. they both reach approximately 2140RPM's.
My old cruise speed at 1750 RPM's was 22.5 knots. The new speed is 25 knots
at 1750. The top end went from 27.5 knots to over 30 knots. I had two spare
wheels that I had reworked by another company to class 1 and tried them
both with nearly the same results. In addition to the increased speed, I
also have a remarkably smoother boat and I am burning less fuel. Thanks
again Wildcat!!
