R2 Quality Castings is Wisconsin's choice for precision investment casting, industrial propeller manufacturing and rapid prototype development. We have decades of experience producing high quality, thoroughly dependable cast propellers for a wide variety of industrial and manufacturing applications. 

What are Industrial Propellers Used for? 

Industrial propellers are used to create air or fluid flow and enhance ventilation, heating and cooling exchange and circulation in food mixers, industrial mixers, HVAC systems and aviation & aquatic applications. 


What are the Different Types of Industrial Propellers? 

Industrial propellers are available in several custom and mass-produced shapes and sizes to meet the specific demands of unique industries. Types of industrial propellers include:


  • Axial flow fans- used for moving gases in air and ventilation systems


  • Centrifugal fans- used for moving air radially in high pressure air and material handling units



  • Mixing propellers- used for agitation, mixing and creating chemical reactions in liquids and slurries in chemical, food, beverage, wastewater and pharmaceutical processing 


  • Process stirring propellers- used for agitation and mixing chemicals and substances in manufacturing 



  • Gas turbine blades- used for for high-temperature, high-pressure energy extraction with aircrafts and power generation



We manufacture industrial propellers for a wide variety of applications. 


Why are Casting and Investment Casting Used for Industrial Propellers?

The unique properties of cast and investment cast industrial propellers are designed to resist corrosion and withstand extreme temperatures to optimize aeration and substance flow according to exact specifications. 

Casting and investment casting are flexible and affordable solutions for manufacturers to form aluminum, bronze, stainless steel, and other metals into industrial propellers with precise sizes, angles and weight distributions to manipulate water, gasses, chemicals, food, manufacturing materials and more. 

Pilots, manufacturers, marine explorers and pharmaceutical drug producers are just a few of the professions dependent on the high-performing consistency provided by intricately designed industrial propellers. 


What are the Benefits of Investment Casting for Industrial Propellers? 

Investment casting yields a uniform grain structure and greater strength in the metals used for industrial propellers, and it saves costs and reduces production time for large volume productions by decreasing material waste and minimizing the need for extensive post-casting machining. 


Other advantages of investment casting for industrial propellers include:

  1. Rapid prototyping for design and testing 

  2. Durability for long-term performance in demanding environments

  3. Creates a smooth surface finish, reducing drag and improving flow efficiency


Without casting and investment casting, industrial propellers would fail to deliver accurate results in manipulating liquids, gases and other substances, creating safety issues and inefficiencies in their applications.
