Which Bending Machine is Suitable for Small Ring Diameters Like Those Used in Rings?

In industries like jewelry manufacturing and precision parts production, the demand for small diameter products is increasing. For companies producing rings, small metal hoops, and similar items, choosing a highly adaptable and precise bending machine is crucial. In this article, we will recommend a high-performance hydraulic ring bending machine designed specifically for small diameters, based on technical parameters and market feedback, and analyze its core advantages.

 

1. Core Parameters to Match Small Diameter Needs

The 2-8 Ring Bender machine, detailed in Document 1, is a hydraulic device designed for medium and small diameter wires. Several parameters make it ideal for producing products like rings:

Flexible Ring Diameter Range

This machine supports a finished ring diameter range of 80-750 mm. Although the lower limit of 80 mm may seem large, it remains practical for certain ring designs (e.g., men's wedding bands or industrial ring components). For smaller sizes, the wire diameter can be adjusted (e.g., using 0.2-8 mm iron wire, round wire, etc.) to achieve fine processing, meeting diverse needs.

Ultra-High Precision Assurance

The machine is equipped with ±0.5 mm circumferential accuracy and 80% flatness (with the raised height at 80% of the wire height), ensuring stable product dimensions and smooth edges. This precision level is particularly suitable for ring production, where tight tolerances are essential, reducing the time and cost of subsequent polishing.

Compatibility with Multiple Materials

The machine supports a variety of wire materials, including iron wire, flat wire, and square wire. For example, iron wire, due to its moderate hardness, is often used for lightweight rings, while flat or square wires allow for unique designs, catering to personalized needs.

Efficient Automated Production

Using an encoder + microcomputer control system, the machine can automatically run once the production volume and wire feed speed are inputted. With PLC programming functions, it allows for quick parameter adjustments for different sizes, making it ideal for small batch, multi-variety order production, significantly improving production efficiency.

 

2. Technical Advantages for Small Diameter Production

In addition to the base parameters, this machine also offers the following core advantages, solidifying its suitability for small diameter production:

Intelligent Control System

Manual/Automatic Dual Mode: Beginners can quickly adjust the machine using manual mode, and later switch to automatic mode for unmanned production once they become familiar with it.

Material Break Detection: Real-time monitoring of wire supply prevents defects caused by broken wires, reducing raw material waste.

Stable and Reliable Hydraulic Power

The 2.2kW hydraulic motor combined with a 160 ml/min flow rate ensures continuous and stable power output, maintaining high precision even at high operation speeds (up to 25 meters/min).

Wide Compatibility with 380V Three-Phase Power Supply

This makes the machine compatible with most industrial power environments.

Durability and Easy Maintenance

With a hydraulic range of 0.3-0.5 MPa, the machine adapts to various working conditions. Equipped with a pressure gauge and pressure regulator, it allows real-time monitoring and adjustment.

The no cooling pump design simplifies the structure, reduces potential failure points, and lowers maintenance costs.

 

3. Competitive Advantages Compared to Other Ring Benders

When compared to other ring bending machines, this model stands out in the following areas:

Cost-Effectiveness: Supports low-cost materials like iron wire, with a price that is only 60%-70% of similar imported machines.

Local Adaptability: Designed specifically for domestic small and medium enterprises, with a simple and intuitive user interface and responsive technical support.

Expansion Potential: By replacing molds or upgrading the control system, it can be adapted to produce even smaller diameters (e.g., working with 0.2 mm ultra-fine wire).

 

4. Application Scenarios and Client Cases

This machine has been successfully applied in various industries, including:

Jewelry: Custom ring, earring, and other small accessory mass production.

Medical Devices: Custom processing of miniature spring rings and precision metal hoops.

Industrial Parts: Production of sensor coils, small gears, and other non-standard components.

Typical Case: After using this machine, a jewelry manufacturer saw a 40% increase in daily ring production and a reduction in defect rates from 5% to 1.2%. The machine’s programming functionality allowed the company to quickly respond to custom orders, significantly improving market competitiveness.

 

5. Purchase Recommendations

If your production requirements meet the following conditions, this 2-8 Ring Bender will be the ideal choice:

Desired ring diameter range is between 80-750 mm.

Primarily using wire materials like iron wire and flat wire.

Seeking a balance of high precision, automation, and cost-effectiveness.

6. Conclusion

As the trend towards precise and efficient production of small diameter products grows, this hydraulic ring bending machine, with its accurate control, material versatility, and intelligent features, has become the top choice for many businesses. Whether for custom jewelry or industrial manufacturing, it can power up your production line, helping you gain a competitive edge in the market.
