Manufactured to Perfection

Perfection underlies every part of the propeller manufacturing process at VEEM. Harnessing patented pattern-less molding and manufacturing techniques, VEEM can obtain a high-quality, near final dimension casting for a wide variety of unconstrained propeller design specifications. The benefit of this truly bespoke integrated design and manufacturing process is that performance and efficiency is always optimized for the specific application.

While many propeller manufacturers offer semi-Computer Numerical Control (CNC) machined propellers, VEEM’s high-accuracy, 5-axis CNC machinery is unique. VEEM propellers are 100% CNC machined to hair thickness accuracy over every square inch of the propeller, including the boss and high BAR overlapping blade propellers. Every VEEM propeller is S-class as a minimum. The blades are then luster polished to maximize propulsive efficiency.

The human error that VEEM eliminates in its manufacturing process allows for absolutely identical propellers to be produced every time. This guarantees propellers that are perfectly balanced from side to side, boat to boat, year to year.

VEEM are also one of the only propeller manufacturers in the world that undertake metal alloying in house, guaranteeing that all materials are of the highest quality. The diminished effects of cavitation on the blades and finer propeller geometry ensure better performance.

In-house Alloying

VEEM Propellers are one of the only propeller manufacturers that undertake metal alloying in house, guaranteeing that all materials are of the highest quality. VEEM Ltd offers a wide range of engineering services that require flawless metal chemistry and are therefore able to perfect the process to offer the highest quality products across the different services.

It is the attention to detail in the metal alloying process that sets VEEM propellers apart from other manufacturers that traditionally use pre-alloyed metals from external suppliers. Through extensive research and development, VEEM has been able to fine-tune the chemical composition of alloys to maximize its mechanical strength, enabling more efficient propeller geometry to be employed.

Complete CNC Machining

While the majority of manufacturers in the market offer semi Computer Numerical Control (CNC) machined propellers, VEEM’s high accuracy, 5 axis CNC machinery perfects every square millimeter of the propeller, producing a flawless product that is manufactured to exact design specifications.

The human error that VEEM eliminates in its manufacturing process allows for absolutely identical propellers to be produced every time. Side to side, boat to boat, year to year, VEEM propellers will be identical to the thousands of an inch, resulting in exactly the same ultimate performance every time.

Additional to this, semi CNC machining and fixed pattern casting means that, unless the casting process is accurate enough to provide an even amount of material to be removed during the machining process, the propellers will stress relieve differently across the face after machining and will no longer be accurate. VEEM has a patented casting process that ensures perfection every time.

Pattern-less Molding

Every propeller has to be designed to suit individual vessel operations to achieve maximum performance and efficiency. The majority of propellers in the market provide an ‘off the shelf’ range of propellers with limited options to change the principle geometry. These minimal changes don’t always suit the application and they therefore miss out on the optimum design process, which provides the biggest gain in propeller performance and smoothness.

VEEM’s advantage is their patented pattern-less molding and manufacturing techniques used to obtain a casting to absolutely any shape with any principle geometry, quickly and cost effectively.

VEEM’s Naval architects and engineers have over 50 years experience designing high-performance propellers that work to achieve maximum speed and smoothness, specific to your vessel’s characteristics and operating conditions. The benefit of truly custom designed propellers is that performance and efficiency is always optimised and cavitation resistance technology can be applied to suit the category of cavitation you experience and eliminate the effects.

The technology behind pattern-less molding also ensures that identical replacements can be made of propellers that are accurate within microns.
