400-ton Press
Product Description
A 400 ton hydraulic press is a heavy-duty machine for metalworking jobs that call for substantial pressing force and dependable operation. It can be used for bending, forming, straightening, pressing, stamping, and other processes involving metal parts and blanks. For many manufacturers, a 400-ton machine is a practical step up when a smaller press no longer has enough capacity, while a much larger machine would be unnecessary.
Choosing the right press is not only about the tonnage. The working area, cylinder stroke, operating speed, control method, and tooling all have a direct impact on how well the machine fits the actual production process. For this reason, the 400 ton press can be configured for a specific application rather than being limited to one fixed setup.
The machine can be used for individual production operations or incorporated into a regular manufacturing line. If you already know the workpiece size, material, tooling dimensions, and required production cycle, these details can be used to work out a more suitable configuration.
Key Features
- Up to 400 tons of pressing force for demanding metalworking applications.
- Hydraulic system pressure up to 25 MPa for the series covered by the technical specifications.
- Rigid steel frame designed to remain stable under heavy working loads.
- Smooth cylinder movement for better control of the pressing process.
- Application-specific stroke selected according to the workpiece and tooling.
- Flexible control options, including manual, semi-automatic, and PLC control.
- Customizable machine layout, including the worktable, cylinder, working space, and other major components.
- Suitable for repeated production cycles when properly configured for the application.
Materials and Construction
The frame is the main load-bearing part of the machine and is built from heavy-duty structural steel. With a press of this capacity, frame rigidity is important because the structure has to withstand considerable force during each working cycle. The main structural components are welded and then machined to achieve the required accuracy and stability.
The working area is arranged to accommodate the workpiece, die, mold, or other tooling. Its dimensions can be discussed during the design stage, which is useful when the standard machine layout does not match the customer's production requirements.
The hydraulic cylinder and power system are selected according to the required pressing force and working cycle. The hydraulic circuit includes the pump, valves, piping, seals, and related components needed for stable operation.
For the equipment series covered by the supplied technical data, the hydraulic system pressure is specified as 25 MPa. The final cylinder dimensions, working table, stroke, motor power, and other specifications for a 400-ton configuration should be confirmed before production.

Why Choose a 400 Ton Hydraulic Press?
The rigid frame gives the machine a solid foundation during pressing. This matters when large or high-strength workpieces are processed repeatedly, as excessive frame movement or deformation can affect the consistency of the finished parts.
The hydraulic drive is another practical benefit. Instead of relying on a simple fixed movement, the working cycle can be set according to the application. This gives the operator better control over the pressing process and makes it easier to maintain consistent results during repeated jobs.
Customization is also an important part of the design. Different manufacturers may need very different working tables, cylinder strokes, open heights, or control systems. A 400 ton hydraulic press can therefore be specified around the actual workpiece and tooling instead of forcing the production process to fit a standard machine.
For customers running batch production, repeatability is equally important. Once the pressure, stroke, speed, and other working parameters have been properly set, the same operation can be repeated with less manual adjustment from cycle to cycle.
Services
Before Ordering
We first look at the actual application rather than recommending a machine based only on tonnage. Our team can assist with:
Press capacity calculation
Worktable and cylinder stroke selection
Workpiece material and size analysis
Working area assessment
Control system selection
Tooling requirements
Customized technical solutions
A part drawing or sample information is especially useful when the press needs to be configured around a particular manufacturing process.
Manufacturing & Quality Control
During production, the main mechanical, hydraulic, and electrical components are checked according to the machine configuration. Before shipment, the press is tested to verify its hydraulic system, electrical functions, and working cycles.
A pre-delivery inspection is also carried out so that major operating functions can be checked before the equipment leaves the factory.
After-Sales Support
After delivery, we can provide assistance with installation and commissioning, operator guidance, routine maintenance, and troubleshooting. Spare parts can also be supplied when required.
Remote technical support is available for customers who need help checking machine operation or identifying possible problems during daily use.
FAQ
Q: What can a 400 ton hydraulic press be used for?
A: A 400 ton hydraulic press can be used for bending, forming, straightening, pressing, stamping, and other metalworking operations that require high pressing force.
Q: Can the 400 ton press be made for a specific workpiece?
A: Yes. The working table, cylinder stroke, open height, operating speed, control system, and other parts of the machine can be selected according to the customer's production requirements.
Q: What should I consider when choosing a 400 ton press?
A: The main factors include the material and dimensions of the workpiece, type of operation, required pressing force, die or tooling size, available working space, and expected production volume.
Q: What hydraulic pressure does the machine use?
A: The supplied technical specifications list a hydraulic system pressure of 25 MPa for the relevant equipment series. The final hydraulic configuration should be confirmed according to the specific machine design.
Q: Can the machine use automatic control?
A: Yes. Depending on the application, the machine can be equipped with a PLC control system or another suitable automation solution. The control method can be discussed during the technical design stage.
Q: What information do you need to configure the machine?
A: For a more accurate recommendation, it is helpful to provide the workpiece drawing, material, dimensions, type of operation, required pressing force, tooling size, and expected production capacity. Based on these details, we can determine a suitable configuration for the 400 ton press.
