Drop-forging

We supply optimal quality, just-in-time, at the best price on the basis of customer specifications and applicable standards, including EN 10243. We take all specifications into account, such as surface specifications, heat treatment and hardening processes.

DROP-FORGING

The extensive equipment meets all of the hot forging requirements of a customer’s specifications.

• Drop-forging hammer and upsetting machines with 1 – 5 t capacity
• Vertical drop-forged (upright forging) up to 6″, 1200 t
• Mechanical presses, 1000 – 4000 t

HEAT TREATMENT

The heat treatment processes take place under monitored, repeatable and certification-compliant conditions. These are largely automated and hence suitable for large quantities.

• (Stress-free) annealing, soft annealing
• BG annealing, FP annealing
• Normalising
• Blower cooling
• Water / oil / polymer quenching
• Tempering
• Hardening
• Case-hardening, gas carburising
• Gas nitriding
• Isothermal annealing heat treatment
• Induction hardening
• Tempering

Components can therefore be supplied in sizes from 500 g up to 150 kg.

COLD-FORGING

Fully automated hydraulic cold-forging press with four stations. An efficient transfer system between the stations together with a fully automated feed ensures high levels of productivity (6 – 8 parts per minute). Necessary additional systems including an electronically controlled phosphating and soaping line are available.

Example products for general mechanical engineering, vehicle construction and automotive

• Shafts and pinions
• Machining depending on intended use

Advantages of the process:

• Excellent surface quality
• Material savings of up to 15%
• Lower energy costs
• Almost finished dimensional forging
• Minimal tolerances / minimal processing allowances
• Better grain flow and excellent fibre orientation for greater solidity
• No distortion angles, no burrs, no mismatches
• High productivity
