Forging presses

Our biggest forging press works with the energy of 35 MN. Process-controlled forging furnaces with a furnace capacity of up to 250 tonnes guarantee proper heat control. Our open-die forging presses from 12 to 35 MN pressing force are capable of producing workpieces weighing up to approx. 28.000 kg. The forging is carried
out by free-running auto-forging manipulators with a load-bearing capacity of up to 40 tonnes.

Hammer mill

In the hammer department, we use steam hammers with a bear weight of 400 to 3.000 kg.
We do the forging in combination with electro-oil hydraulic manipulators or manually. A large auxiliary die bearing makes it possible to forge difficult geometric contours, such as journals, hub disks, double hub disks, etc., with low machining allowances to conform to the fibre. In our open-die forge, the Hammerwerk and forging press department complement each other to form a well-rounded production programme.

Ring rolling mill

Seamless, precise and with a clean surface. Three-dimensionally pre-forged punched discs are rolled into seamless rings on two ring rolling mills equipped with modern control and measuring systems. We roll radial-axial in open calibre:

• Unit weights from 15 to 4.000 kg
• Outer diameters from 250 to 2.800 mm
• Heights from 45 to 700 mm

Heat treatment

Our products are subjected to the required heat treatment in-house. Our range includes:


Quenching and tempering
Normal annealing
BG (microstructure) or BF (tensile strength) annealing
Soft annealing
Solution annealing
Low stress annealing
Hydrogen effusion annealing
Special heat treatments according to customer requirements or specifications
Consulting and problem solving with regard to requirements for quality and heat treatment

Machine shop

An overview of the mechanical equipment:

• Vertical lathes up to 2.800 mm turning diameter
• Tip lathes up to 10.000 mm turning length
• Special boring lathes for machining hollow-forged shafts and cylinders
• Boring and milling machines
• Lathes

Conventional or CNC-controlled machines are used depending on requirements. All products of our heat forging operations can, of course, be mechanically machined. This is done according to customer requirements with cutting allowances, machining dimensions or within the scope of our possibilities up to finish machining.

Material testing

All non-destructive and destructive industry standard tests required for open die forgings and rings can be executed and certified in accordance with quality regulations, specifications or customer requirements.

Quality assurance

Due to our manifold quality inspections we continuously ensure the desired quality requirements of our customers. The many years of experience and qualifications of our employees are representative of the HWE quality seal. This is characterised, among other things, by the fact that all quality inspections are carried out in-house by more than 15 highly qualified specialists. It is worth mentioning that several of these inspection specialists are certified according to DIN EN ISO 9712 Level 3 (UT/PT/MT/VT). Challenge us!
