Today, cold extrusion is one of the most important processes for the economic production of near-net-shape parts in large quantities.
The flexible force-displacement characteristics, the high working capacity and the good adaptation of the hydraulic press to forming operations are the optimum pre-condition for economic cold extrusion.
- The press frame, depending on press capacity and application, may be a particularly rigid pre-stressed
multi-part or compact one-piece design
- Press head designed as oil reservoir with head cover to accommodate the compact press drive
- High pressing speeds to minimise the load on the die and punch due to heating
- Full press force is available over the entire stroke at maximum speed
- Depending on press size and speed one or more variable volume axial piston pumps are mounted on
the press head as submerged pumps
- Servo hydraulic direct drives alternatively equipped with gear pumps or axial piston pumps
- Forged press cylinder and press piston
- Long ram guides infinitely adjustable by tapered gibs
- Efficient programmable control system with operator guidance, product data administration and modem
for remote diagnostics
