ISPIRI WHEELS

FFR SERIES - FLOW FORM TECHNOLOGY/

The Ispiri FFR Series is produced using the advanced German flow forming process. The wheels are initially cast using our low pressure heat treated process increasing strength and durability. The cast wheel is then transferred to the flow forming drum where a combination of heat and pressure applied by three hydraulic rollers compress, stretch and form the wheel barrel to a pre-defined thickness and desired profile.

The condensing and stretching of the metal alters the very nature of the aluminium to produce a wheel barrel that is thinner, stronger and significantly lighter (approx 25%) than a non-flow form cast wheel, with enhanced strength and reduced weight properties comparable to higher priced forged aluminium wheels.

How It's Made/

 
  • ISPIRI ISR6 SATIN GRAPHITE
    Flow Form Process - stage 1

    Immediately after casting the wheel is transfered to the flow forming drum. Three high pressure hydraulic rollers move into position at the top of the wheel barrel.

  • ISPIRI ISR6 SATIN GRAPHITE
    Flow Form Process - stage 2

    The hydraulic rollers move down the barrel applying pressure to compress, stretch and form the entire wheel barrel producing optimal weight savings.

    Flow Form Process - stage 3

    The flow forming process alters the grain of the aluminium to produce a wheel barrel that is thinner, stronger and significantly lighter, with enhanced strength and reduced weight properties comparable to forged wheels.

FFR Lightweight Design/

The major difference between cast and flow formed wheels is in the thickness of the wheel barrel. The flow forming process increases the strength of the aluminium allowing the barrel to be made much thinner and lighter than a conventionally cast aluminium wheel (see diagram 1).

With the FFR Series we set out to create a modern stylish range of flow form wheels that were as light as practically possible. This was achieved by using a minimalistic design and by keeping the inner structural lip at the front of the wheel allowing the entire barrel to be fully flow formed (see diagram 2).
