Custom Propeller Design and Manufacturing Services

 R2 Quality Castings specializes in fabricating marine propellers through precision investment casting. We are capable of casting propellers in a variety of styles including:

  • 3-Blade Marine Pitch Style
  • 2-Blade Weedless
  • 3-Blade Weedless

Our 3-blade marine pitch propellers are designed for a wide variety of applications including blending, mixing and agitating. This style is available with either a full or clipped blade. The 2-blade weedless propellers are designed for use in aeration or mixing equipment. They are most commonly utilized in wastewater applications. 3-blade weedless propellers from R2 Quality Castings are also ideal for wastewater applications in mixing or aeration equipment. Both the 3-blade and 2-blade weedless propellers are manufactured to excel in stringy liquids. Propellers not designed for weeds will become snagged, and wear out much quicker.

Every boat application requires a specific type and size of propeller if it’s going to perform at its highest level. We know every moment you get to spend on the water is important, and if you’re going to buy a new propeller for your boat, it has to be perfect. Investment casting allows us to create most precise prop, giving you with the best experience on the water.

Whether you choose a 3-blade or 4-blade propeller, we’ll make sure your custom design is perfect for your specific application.

Custom Food and Waste Propeller Services

 If you’re looking for a custom propeller for the waste or food industry, we specialize in that too. Our limitation is your application. With our investment casting experts and rapid prototyping technology, you’ll know exactly what you’re getting and have peace-of-mind in knowing each and every custom propeller we produce is meticulously inspected and finished to exceed your standards. 

Custom Propeller Design and Development Servicesinvestment tooling

Including custom options such as clipping, cutting, pitch-changes, special bore sizes, or set screws, R2 Quality Castings provides expert custom propeller designs. Our propeller finishing services are second-to-none and non-destructive testing is a vital step in making sure our products perform reliably and safely.

Some of our custom propeller services include:

  • Static balancing: the ability to maintain balance or the center of gravity is where the axis of rotation is, so rotation doesn’t occur due to gravity.
  • Clipped propellers: are perfect for draft tube applications
  • Standard Setscrew(s): we have the ability to custom make set screw prop adapters to your specifications.
  • Custom bores: the bore is the hollow center of the propeller, where it fits on the shaft; we can customize the finish to be straight, tapered, threaded, or broached.

Due to the process of investment casting, R2 Quality Castings already set up for your custom propeller. We incorporate modern technologies into our process so you can see exactly what your custom propeller will look like before we begin the investment casting process.

For rapid prototyping, we use:

  • CAD / CAM and SolidWorks
  • Scale Part Model Production
  • 3D Printing Prototypes
  • Wax Injection Molding

R2 Quality Castings uses a wide variety of alloys for custom propeller applications. If you don’t see the metal you want your custom propeller made from, contact our custom propeller specialists to request it.

Our custom propeller fabrication materials include:

  • 300 and  400 Series Stainless Steel
  • Precipitation Hardening Steels
  • Nibral
  • Bronze
  • Hastelloy
  • Alloy 20
  • Aluminum
  • Other Materials Available Upon Request

Our custom propeller finishing options are:

  • 36# Grit: a standard finish removing burrs and other imperfections – the metal is polished to a uniform 36 grit
  • Roto-dull: high-speed finishing for deburring, descaling, and finishing investment casting made parts – reduces vibratory process cycles for deburring of castings
  • Dairy Buff (#4 Finish): a finish most commonly used in the medical and food industries – generally for stainless steel mixing propellers.  A #4 finish enhances the appearance and dramatically inhibits microbial growth
  • Mirror Buff (#8 Finish): this finish removes all surface defects - the quality of the mirror buff finish depends on the metal, in fact some steel alloys and aluminum can’t be brought to a mirror finish

Whether you need one custom propeller or 5,000, we can create the perfect customized propeller for your needs.

Our gallery showcases everything from investment cast mold production to finishing and polishing of industrial propeller castings. Marine propellers from R2 Quality Castings can be customized with a variety of finishes and materials to suit your specific application.
