Fontijne Grotnes developed a unique flow forming process and designed the fastest machine for this application in the world to optimise the weight of rims and wheels. This process was developed in cooperation with M&M Machinery Group and is equipped with proven technology. This was confirmed by the fact that the application for a patent was granted. The Flow former can be integrated into either new rim profiling lines or existing rim lines and as a process within one-piece production systems.

 

 The main advantages of the Pro Flow compared to other systems:

• Reduced deformation forces
• Shorter production time
• Reduction of energy costs
• Less wear on tooling
• Accurate control of geometry/tolerances
• No process cooling required
• Limited process lubrication
• The Flow forming process does not require any calibration prior for
  Flow forming (for steel rims).
