The hydraulic free forging press can utilize various molds to perform precision forging in scenarios with different shape processing requirements, making it suitable for small-batch production.

The hydraulic free forging press can perform free forging on metal blanks without molds, making it particularly suitable for sites with single-piece, small-batch production, and the processing of large forgings.

Our hydraulic free forging press has a forging pressure range of 630 tons to 12500 tons. This pressure level can handle the processing of large-volume, high-strength metal billets. It offers high flexibility, meeting the demands of small-batch production with specific forging requirements.

The single arm open die forging press features a C-shaped or open structure overall, with the machine body welded or cast from steel plates. One side is a column or support arm, and the other is an open space. This structure provides ample operating space, allowing access to the workpiece from three directions, making it highly suitable for situations requiring frequent mold installation and workpiece changes.

The single arm open die forging press manufactured by us is easy to operate and allows for easy observation of the forging process. It offers high flexibility and is suitable for various forging processes, especially for small-batch, multi-variety forging production. Additionally, its simple single-arm structure means a small footprint, resulting in lower investment costs for small-scale forging production.

The single arm press is convenient and flexible to use, primarily targeting small-part forging and auxiliary processes on large forging production lines, as well as rapid forging of small quantities of parts in machining workshops and repair shops.

The single-arm design (C-shaped machine body) provides open space, facilitating mold installation and workpiece operation. It is suitable for multi-directional processing and applicable to processes such as free forging, die forging (for small to medium-sized forgings), stamping, extrusion, and straightening, especially suitable for workpieces with complex shapes or those requiring lateral operation.

The single arm open die forging press is suitable for processing various metal materials such as copper, aluminum, stainless steel, and titanium. It can also be used for non-metal material forming, but suitability depends on specific material characteristics and process requirements.

Standard forces include 10 t, 20 t, 40 t, 60 t, 100 t, and 200 t (630–1,000 tons). Customization for other capacities is supported upon request.

A vertical ring rolling machine feeds in the vertical direction, occupies less floor space, and automatically stabilizes the ring’s center of gravity—ideal for small- to medium-sized rings. Horizontal machines suit large-diameter, wide rings.

Standard vertical machines process rings from 55 mm to 1,300 mm in outer diameter. Custom sizes are available upon request.

Select based on forming needs: choose a standard vertical machine for radial-only forming; for combined radial and axial control, opt for a radial-axial model.

Standard models require 90–150 days. Custom configurations depend on specific requirements.

Our ring rolling machines are all manufactured from cast steel, ensuring stable and rigid equipment structure and robustness for durability. This guarantees the accuracy and stability of roll movement, thereby improving the processing precision of ring parts and significantly reducing scrap rates. Additionally, by adopting a CNC system, high-precision processing of ring dimensions, shape, and surface quality can be achieved, significantly enhancing overall engineering efficiency.

Our ring rolling machines can produce various types of rings of corresponding sizes, including flanges and sealing rings, with guaranteed production accuracy.

Our radial-axial ring rolling machine operates with an an electronic handwheel, features a high degree of automation, and uses a cumulative method of local pressurization and continuous small deformation, which can achieve high-precision rolling of ring parts. This meets the wind power industry's demand for high-precision, large ring parts and is suitable for large-scale production of wind power tower flanges and main shaft rings.

It adopts a high-temperature resistant design and can operate for short periods in environments up to 1200℃ (continuous operation requires intermittent cooling).

Supports O.D. 300mm – 700mm ring part handling. The specific range depends on the gripper and load configuration.

Our intelligent manipulator has 5 axes, possessing high flexibility. It can handle most forging transfer tasks, especially the grasping, flipping, and placement of ring parts. It is suitable for scenarios involving shafts, discs, and rings where the transfer path is relatively fixed.

The CNC intelligent forging manipulator is primarily used in the forging process for retrieving workpieces from heating furnaces, feeding/orienting in conjunction with forging hammers/hydraulic presses, performing workpiece flipping or rotation, post-forging transfer, cooling, or positioning at workstations.

Typically supports forging diameters from 60mm to 2800mm+, with a nominal load capacity of 5-1000 kN. The gripper jaw structure supports adjustment or customization.

Yes, it supports preset process programs, one-key operation, automatic feeding and positioning, and can be linked with the main equipment for integrated control.

A rail-bound manipulator operates fixed on preset rails, completing loading, unloading, and positioning via hydraulic drive. It is suitable for fixed paths, high repetitive positioning accuracy, and heavy workpieces. A rail-less manipulator is a free-moving loading/unloading equipment with self-propelled capability (usually wheel-driven), suitable for multi-variety, small-batch production, or spaces with limited access.

The rail-bound hydraulic forging manipulator is only suitable for horizontal straight-line rail operation. If slight curves or slopes are needed, a special chassis or track-changing mechanism can be customized.

Bearing capacity required is ≥5T/m2. A reinforced concrete foundation is recommended. Track installation requires leveling, grouting, and thermal expansion treatment.

The gripper jaws of the mobile transport manipulator support quick replacement to accommodate various forging shapes such as round cakes, blocks, rings, and irregular forgings.

A 'rail-bound + rail-less' hybrid system can be designed. For example, heavy workpieces can be transported by a rail-bound machine to a transfer area, then sorted by a rail-less machine to multiple workstations.

Yes, structural dimensions, load capacity, gripper jaw type, control system, power supply method, etc., can be customized according to production line layout, workpiece characteristics, and operational requirements.

The rolling wheel of a CNC orbital forging press can oscillate around its central axis, thereby expanding the forming area and optimizing force application. It can achieve control of more complex cross-sections (such as V-shaped, T-shaped sections), resulting in more uniform rolling and higher forming precision.

Choose the separated type for large sizes with multiple variations, and the vertical type for small sizes with high precision. Choose the vertical type for standardization, and the separated type for customization.

From round bar clamping to roller propulsion and rocking head oscillation, all are hydraulically adjusted. Compared to previous common old-style orbital forging presses, efficiency is improved by over 50%. With uniform and fixed-stroke control systems, it can save approximately 50% energy.

A CNC radial forging machine is a high-precision, high-repeatability, and highly automated forging equipment, primarily used for closed-die or semi-closed-die forming of metal billets. It features a high degree of automation, suitable for unmanned production lines.
