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 Three Dies Pointing Machine is designed for reducing and flattening the ends of stainless steel tubes before cold drawing, welding, forming, or assembly. Its three-die hydraulic arrangement uses two side dies and one upper die to shape the tube end in a controlled sequence.
This configuration is particularly useful when the required end profile is flattened rather than simply reduced in diameter. Instead of relying on a single pressing direction, the side dies first bring the tube into position before the upper die completes the flattening operation. This helps control deformation and maintain more consistent end dimensions from one workpiece to the next.
The three-die arrangement is different from machines that compress a tube from two sides or use multiple dies around the entire circumference. Here, the forming sequence is the main part of the process: the two side dies move inward first, followed by the upper die.
| Machine Configuration | Typical Forming Approach | When It Makes Sense |
| Two-die | Compression mainly from two opposing directions | Basic tube-end reduction and applications with less complex forming requirements |
| Three-die | Two side dies position and compress the tube, followed by upper-die flattening | Flattened ends, special profiles, and stainless steel tube forming where controlled deformation is required |
| Four or more dies | Forming force is distributed around more directions | Applications requiring circumferential reduction or higher control of round-section deformation |
The Stainless Steel Hydraulic Three Dies Pointing Machine is therefore not simply a smaller version of a four-die pointing machine. Its value lies in the forming sequence and the type of end geometry it is intended to produce.
The tube is positioned in the die area according to the required forming length and end dimensions. Once the cycle begins, the hydraulic cylinders execute the programmed movement rather than relying on manual pressing operations.
First, the left and right dies move toward the center and compress the tube from both sides. This brings the material into the required intermediate profile. The upper die then moves downward to complete the flattening operation.
After the forming stroke, the three dies return to their starting positions and the finished tube can be removed. The same sequence is repeated for the next workpiece.
The model should be selected from the actual tube dimensions rather than from outside diameter alone. Wall thickness, stainless steel grade, required flattened dimensions, tube length, production quantity, and downstream process all affect the required machine configuration.
| Selection Item | Why It Matters |
| Tube outside diameter | Determines the basic pointing range and die working size. |
| Wall thickness | Thicker stainless steel requires greater forming force. |
| Material grade | Different stainless steel grades can have different forming resistance. |
| Required end profile | Determines die geometry and the forming sequence required. |
| Production volume | Helps determine hydraulic capacity, automation requirements, and suitable machine size. |
| Next production process | The pointed or flattened end needs to match the requirements of drawing, welding, assembly, or further forming. |
For non-standard tube shapes, supplying a product drawing or sample is recommended. Fangrong can use the workpiece information to determine the appropriate die configuration and machine specification.
The FR-25, FR-50, FR-100, and FR-160 models cover pointing ranges from φ25 mm to φ160 mm. The listed wall thickness capacity increases from 3 mm to 12 mm as the machine size increases. Larger models use a hydraulic arrangement consisting of one upper cylinder and two side cylinders, with forming force and motor power matched to the working range.

Custom specifications are available according to tube dimensions, material, forming requirements, and production conditions. The specifications above are reference values, and actual parameters may vary by material type.
This Stainless Steel Hydraulic Three Dies Pointing Machine is used where the tube end needs to be changed from its original round profile into a flattened, reduced, or specially formed section. The finished end can then enter a subsequent manufacturing operation without relying on inconsistent manual preparation.
Common applications include stainless steel decorative tubes, furniture tubing, handrails and railings, door and window profiles, automotive structural tubing, architectural stainless steel products, precision tubing, and special-shaped tube production.
For manufacturers producing different tube profiles, interchangeable or customized dies can be considered according to the required end shape and dimensions.
The standard machine uses hydraulic control for the three-die forming cycle. For production lines with higher output requirements, the equipment can be configured with automatic loading and unloading systems to reduce manual handling between cycles.
Customized hydraulic force, die dimensions, machine size, control configuration, and automation can also be considered. The final configuration depends on the workpiece and the production line rather than applying one standard setup to every stainless steel tube application.
Fangrong was established in 1998 and has more than 26 years of experience in the design and manufacture of straightening machines, cold drawing equipment, and related metallurgical machinery. Its equipment is used in more than 60 industries and has been supplied to over 10,000 customers in more than 60 countries and regions.
The company operates two manufacturing facilities in Guangdong Province. Dongguan Fangrong Metallurgical Equipment Co., Ltd. in Dalang Town, Dongguan City is the headquarters and primary manufacturing base, producing precision cold drawing machines, straightening machines, thread rolling equipment, and related machinery.
Yangjiang Fangrong Machinery Co., Ltd. in Yangdong District, Yangjiang City provides additional manufacturing capacity and supports equipment production and delivery.
Manufacturing begins with the workpiece requirements rather than a fixed machine configuration. Tube dimensions, forming force, die arrangement, hydraulic capacity, and control requirements are confirmed before production.
Engineering and Component Preparation
Mechanical drawings and hydraulic schematics are reviewed first. Steel plates, hydraulic components, electrical parts, cylinder components, and die materials are then prepared according to the approved configuration.
Structural Fabrication
The main frame and supporting structure are fabricated and welded before machining. Key mounting surfaces are subsequently processed to provide the required assembly accuracy.
Die and Cylinder Work
The upper and side forming components are manufactured according to the selected pointing range. Cylinder barrels, piston rods, die seats, guides, and other critical components are machined and inspected before installation.
Hydraulic and Electrical Integration
The hydraulic power unit, cylinders, valves, pipelines, control cabinet, and PLC system are connected after mechanical assembly. The three cylinders are checked through the complete forming sequence.
Machine Trial
The Stainless Steel Hydraulic Three Dies Pointing Machine is first operated without material to check movement and control functions. Test tubes can then be processed to verify the forming result, cycle operation, and response of the hydraulic system.
