About us

Experts in forming -GFU- Maschinenbau GmbH

Since 1989 GFU - Maschinenbau GmbH is realizing customized concepts according to customer's requirements. We develop, design and manufacture forging machines for hot and cold forming, individual upsetting presses, reduction/expanding presses and high-speed end-forming (flow forming) machines.

Reaching our customer's requirements is always our goal, along with the corporate objective to achieve:

  • Highest durability
  • economic benefits in the use of raw materials
  • weight reduction
  • production of a homogeneous grain structure
  • allowing for near net shape production
  • easy programming / plain programming structure
  • profitability of the machines
  • easy access for service
  • satisfied customers and reliable quality.

Both hot forming and cold forming:
Customers in automotive industries, aviation, oil and gas exploration, construction industries and various other sectors are trusting in machines and production lines made by GFU.

Rotor shaft

GFU use 3 different technologies in combination to produce high perfomance, light weigth rotor shafts for EV, BEV cars.
- Upsetting
- High speed end forming
- Pushpointing
Main advantages for the rotor shaft - made by GFU:
- ligth weight
- very low unbalance
- low cycle time
- no welding seam
- higher dynamics of the motor
- low part variety
- low manufacturing cost
- high performance EV, BEV, e-drive, E-Motion, E-Mobility, Rotor shaft production line
