We offer a comprehensive range of precision metal processing equipment, including straightening, cold drawing, pointing, chamfering, cutting, thread rolling machines, and drawing dies, tailored for tube, bar, and wire materials across diverse industries.
The Stainless Steel Hydraulic Four Dies Pointing Machine is used to reduce and taper the end of stainless steel pipes, tubes, bars, and profiles before cold drawing or other downstream forming processes. The prepared end gives the material a smaller section that can be introduced into the drawing die and gripped by the drawing equipment.
Instead of pressing the material from one or two directions, this machine uses four hydraulic cylinders to close four dies toward the centre at the same time. The forming force is distributed around the workpiece, which helps control eccentricity, oval deformation, and uneven marks during end reduction. It is suitable for stainless steel materials where end preparation needs to remain consistent from piece to piece.
The stainless steel pipe, bar, or profile is positioned at the centre of the die set. When the forming cycle starts, four hydraulic cylinders move the dies inward simultaneously. The material is compressed from four sides and plastically deformed at the end until the required reduced or tapered section is obtained.
The four dies work as one forming unit rather than relying on a single pressing direction. This keeps the workpiece closer to the centre during forming and reduces the risk of an off-centre pointed end. After one forming cycle, the prepared end can be transferred to the next operation, such as cold drawing, pulling, or straightening, according to the production line.
For stainless steel tube processing, the forming result is not determined only by hydraulic force. The direction in which the force is applied also affects the shape of the reduced section. A four-die arrangement gives the material support from four directions, making it more suitable when the pointed end needs controlled geometry before drawing.
This configuration can reduce problems such as eccentric tube ends, excessive ovality, uneven deformation, and repeated forming. For production lines processing different stainless steel sizes, the use of replaceable dies also makes it possible to change the forming setup between production runs.
| Forming Method | Typical Consideration |
| Two-die forming | Force is concentrated from two directions, so material positioning and deformation control become more important. |
| Three-die forming | Adds another forming direction but still has an uneven number of dies around the workpiece. |
| Four-die forming | Four dies close toward the centre simultaneously, providing more evenly distributed forming pressure around the material. |
The model should be selected according to the actual material and production requirements rather than pipe diameter alone. Outer diameter, wall thickness, material strength, required pointed-end shape, and production volume all affect the required machine configuration and die design.
The standard FangRong range covers FR-25, FR-50, FR-100, FR-160, and FR-250. The available pointing range extends from φ25mm to φ250mm, while the specified wall thickness range reaches up to 40mm on the FR-250 model.
The following table gives the standard specifications of the Stainless Steel Hydraulic Four Dies Pointing Machine. The cylinder arrangement, motor power, machine size, and weight increase with the forming capacity of the model. Custom specifications can be provided according to material, tube size, and production requirements.

The pointed section is the connection between tube-end preparation and the following drawing operation. If the reduced end is off-centre, excessively oval, cracked, or dimensionally inconsistent, it can make die entry and gripping more difficult and increase the chance of rework.
The four-cylinder hydraulic arrangement helps keep the forming action more evenly distributed around the tube. Combined with machined guide surfaces and properly matched dies, the machine is intended to produce repeatable pointed ends for subsequent drawing and cold-processing operations.
The actual forming result still depends on the stainless steel grade, tube dimensions, wall thickness, reduction ratio, die design, and process settings. These factors should be confirmed before the final machine and tooling configuration is determined.

Q: What materials can the four-die pointing machine process?
A: The machine is mainly used for stainless steel and carbon steel round pipes, tubes, and solid round bars. Special cross-sections can also be considered with customised dies according to the material and forming requirements.
Q: How do I choose between FR-25, FR-50, FR-100, FR-160, and FR-250?
A: Start with the maximum outside diameter and wall thickness of the material to be processed. Material grade, required pointed-end shape, production volume, and forming requirements should also be considered before confirming the model.
Q: What is the advantage of four hydraulic dies?
A: Four dies close toward the centre from four directions, distributing the forming force more evenly around the workpiece. This helps control eccentricity and oval deformation during end reduction.
Q: Can the Stainless Steel Hydraulic Four Dies Pointing Machine prepare tube ends for cold drawing?
A: Yes. End reduction is one of its main applications. The pointed section is formed so the tube can enter the drawing die and be gripped by the downstream drawing equipment.
