An 800 ton four column hydraulic press is built around a 1400 mm × 800 mm worktable and dual 55 kW servo motor-driven hydraulic units, providing the working area and pressing capacity required for large composite panels, wide mold bases, and other heavy forming applications. The large working envelope allows larger tooling to be positioned within the press frame, while the four-column structure provides a stable load path for high-tonnage forming applications.
A 700 mm open height and 300 mm stroke keep cycle geometry compact for repeat pressing, while a 17.6 mm/s working speed and 210 mm column diameter hold consistent approach speed and frame rigidity under full load. A 15 HP oil cooler and a swing-arm control pendant complete the standard build for extended production runs.
Applications
Large mold bases and forming dies require a worktable wide enough to hold the full tooling footprint in one clamping cycle. The 1400 mm × 800 mm effective worktable provides a larger tooling area for wide mold bases and forming dies, subject to the actual die footprint, mounting requirements, and available column clearance.
Composite panel pressing for flat or lightly contoured panels needs steady clamping pressure held evenly across the full panel width during the cure or forming dwell, since local pressure variation can affect resin flow and final panel thickness. The dual 55 kW servo motor-driven hydraulic units provide the hydraulic power required for the press, while the hydraulic control system is configured to maintain pressure during the dwell phase of composite forming cycles, supporting stable forming conditions across the panel area.
Heavy components such as thick forged or cast blanks that need flattening or sizing under high tonnage benefit from the 210 mm column diameter, which provides a substantial structural section for supporting high-tonnage forming loads. Actual frame and platen deflection depends on load distribution, tooling design, and machine configuration, especially when the load sits off-center on the 1400 mm wide table.
Industries
Composite materials fabricators use this press for panel pressing and consolidation work, where the wide worktable and steady servo-controlled pressure maintain even resin flow across large panel sections rather than concentrated near the ram centerline. See the Composite Materials industry page for related forming requirements.
Heavy equipment fabricators use the same frame for sizing and flattening thick forged or cast blanks before machining, where consistent clamping force across an off-center load matters more than cycle speed.
800 Ton Four Column Hydraulic Press Key Features
On large mold forming jobs where the tool sits off-center on the table rather than centered between the posts, the 210 mm column diameter provides a substantial structural section for supporting high-tonnage forming loads. Actual platen deflection and thickness uniformity depend on tooling design, load distribution, and the specific forming process.
The hydraulic system provides a working speed of 17.6 mm/s, powered by dual 55 kW servo motor-driven units, while the hydraulic control system maintains steady output through the dwell phase of a composite forming cycle.
Extended composite pressing dwell cycles generate more heat in the hydraulic oil than fast blanking work does. The 15 HP oil cooler helps control hydraulic oil temperature during extended production runs, supporting more stable hydraulic performance over repeated cycles.
Compared to a fixed control station, the swing-arm control pendant allows the operator to move the control point toward whichever side of the 1400 mm table the mold or panel is loaded from, which matters more here than on a narrower press since the extra table width would otherwise add walking distance between the loading side and a stationary control station positioned on the opposite side of the press.
Note: For applications involving significantly off-center loading, the tooling layout and load distribution should be reviewed with our engineering team before final machine configuration.
For lower-tonnage pressing applications where a more compact machine footprint is preferred, see our C Frame Hydraulic Press range.

Frequently Asked Questions
Is an 800 ton four column press oversized for smaller composite panel work?
The 1400 mm × 800 mm worktable and 800 ton rated force make this machine better suited to large mold bases, wide composite panels, and other high-tonnage applications than to small parts. For smaller composite panels, a lower-tonnage four-column model may offer a more compact and economical solution, so it is worth comparing the required panel size and forming force before choosing the larger frame.
What working speed can I expect from this 800 ton hydraulic press?
The hydraulic system provides a 17.6 mm/s working speed, powered by dual 55 kW servo motor-driven hydraulic units, while the control system maintains steady output through the dwell phase of a composite forming cycle. Actual cycle time depends on panel thickness and cure requirements specific to the material being pressed.
Is the 15 HP oil cooler necessary for composite pressing, or only for continuous production?
The 15 HP oil cooler is most critical for continuous, back-to-back composite pressing runs where dwell time per cycle is long enough to push steady heat into the hydraulic tank. For occasional single-shift use with shorter dwell cycles, oil temperature is less likely to drift enough to affect approach speed.
How does the 1400 mm × 800 mm worktable compare with a narrower four-column press for large mold work?
A 1400 mm × 800 mm table holds wider mold bases inside the available working area without trimming the bolster, which a narrower four-column model cannot do without splitting the tool. For panels wider than the column span allows entirely, a Gantry Hydraulic Press removes that width limit rather than working around it.
What should I confirm before ordering a large hydraulic press machine for composite panel production?
Confirm the mold or panel footprint against the 1400 mm × 800 mm worktable of this 800 ton hydraulic forming machine, check that the 700 mm open height and 300 mm stroke cover the tool height and draw depth needed, and verify the floor foundation can carry an 800 ton class machine before installation.
Standard lead time is typically 45-60 days, backed by a 12-month warranty on core components. Confirming panel width, mold footprint, and oil cooler needs before ordering avoids rework once an 800 ton four column hydraulic press is running in production.
