Equipment Instructions

A 315T four-column Hydraulic Press (315-ton four-post hydraulic press) is a heavy-duty industrial machine designed for high-force metal forming and assembly operations. Here are its key specifications, performance features, and typical applications:

Core Specifications

Nominal force: 3150 kN (315 tons)

Max. opening height: Typically 900–1200 mm

Slider stroke: 600–800 mm

Table size: ~1200 × 1000 mm to 1600 × 1200 mm

Slider speed: ~15–25 mm/s (working), ~60–100 mm/s (rapid advance/return)

Power: ~18.5–30 kW (motor-driven hydraulic pump)

Frame structure: Four-column, two-beam (or three-beam) design, with high rigidity and anti-deflection capability.

Performance Features

• Heavy-duty rigidity: The four-column design with thick steel beams provides exceptional stability, minimizing deflection even under full 315-ton load.

• Precision control: Equipped with PLC and touchscreen HMI, supporting manual, semi-automatic, and automatic operation modes. It can store multiple process recipes for quick changeovers.

• Adjustable parameters: Working pressure, slider speed, stroke, and holding time are fully adjustable to accommodate various materials and forming processes.

• Reliable hydraulic system: Uses a cartridge valve manifold with a large flow rate, ensuring smooth operation, minimal leakage, and reduced hydraulic shock.

• Safety features: Includes hydraulic overload protection, emergency stop, safety light curtains, and dual-hand operation buttons to protect operators and prevent equipment damage.

• Energy efficiency: Modern models often incorporate servo-hydraulic systems, which adjust pump output based on load, significantly reducing energy consumption compared to traditional fixed-pump systems.

Typical Applications

Deep drawing: Forming large, deep parts such as automotive body panels, kitchenware, and industrial containers.

Stamping and bending: Processing thick metal sheets and profiles for structural components.

Straightening and calibration: Correcting the shape of heavy-duty shafts, gears, and structural beams.

Powder metallurgy and composite molding: Compacting high-density materials under high pressure.

Press-fitting: Assembling large components like bearings, gears, and axles into heavy machinery.
