Flow forming lathe
Pro Flow Fontijne Grotnes

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.

Return on investment

Up to 25% weight can be saved, depending on the rim size
On 3 million rims, up to 4000 ton of steel can be saved per year
Compared to competitive processes energy costs can be saved,
up to € 275,000 per year, per Flow former!

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).
