3-8mm 2D Wire Bending Machine: An Efficient and Precise Solution for Refrigerator Shelf Production
2025-08-26
In the refrigerator manufacturing industry chain, refrigerator shelves are core components, and their processing efficiency and precision directly affect the production schedule and quality of the entire refrigerator. Traditional refrigerator shelf processing relies on semi-automatic equipment, which has issues such as incomplete wire straightening, poor bending accuracy, and long mold change time. Especially for the production of shelves made of 3-8mm iron wire, insufficient equipment stability often leads to product dimensional deviations and a persistently high rework rate. However, the 3-8mm 2D wire bending machine, custom-developed for the refrigerator shelf industry, completely addresses the pain points of traditional processing through full servo drive, high-precision mold configuration, and intelligent operation design, making it a core piece of equipment for refrigerator accessory enterprises to reduce costs and improve efficiency.

Hardware Configuration: Tailored Exclusively for Refrigerator Shelf Processing
In terms of hardware configuration, this 2D wire bending machine can be called a "dedicated setup for refrigerator shelf processing." The equipment uses a three-phase 380V + ground wire power supply, which is compatible with industrial production standards. Its core power system is equipped with a domestic ORI servo motor, with a total power of approximately 7.3kW, distributed into a 3.8kW wire-feeding servo, a 1.5kW bending servo, a 1.0kW cutter servo, and a 1.0kW servo lifting motor. The four-axis coordinated drive ensures precise and synchronized movements.
Key components are made of top-tier materials in the industry:
- 18 sets of straightening wheels are manufactured from national standard Cr12 (a type of cold-work die steel), with a hardness of 58-62 HRC (Rockwell Hardness C Scale), which can effectively correct the bending deformation of 3-8mm iron wire and ensure wire straightness.
- Both the bending molds and wire-feeding wheels are precision-machined using high-quality SKD11/51 materials (high-performance cold-work die steels). The wire-feeding wheels undergo national standard special polishing treatment, with a hardness also reaching over 58 HRC, offering excellent wear resistance and preventing wheel surface wear even during long-term processing.
- The cutter motor has strong cutting force, enabling smooth cutting of 3-8mm iron wire with flat, burr-free cut edges, laying a solid foundation for subsequent bending and forming.
Processing Capacity and Precision: Fully Aligned with Refrigerator Shelf Production Needs
In terms of processing capacity and precision, this 2D wire bending machine is fully tailored to the production requirements of refrigerator shelves. The equipment is compatible with round, flat, and square iron wires (and also applicable to wires of other materials such as aluminum and copper of the same specification). For the 3-8mm iron wire commonly used in refrigerator shelves, it can realize full-process automation from wire straightening, feeding, cutting to bending and forming.
Its key performance indicators are as follows:
- Maximum wire-feeding speed: Up to 22 meters per minute
- Maximum bending speed: Approximately 300 revolutions per minute
- Flexible movement directions: The inner mold can move up and down, while the outer mold can rotate 360° clockwise and counterclockwise, with an angle control range of ±180°. It can form various shelf shapes (such as rectangles, U-shapes, hook-equipped structures, etc.) through the combination of 300 action settings.
Taking a 200*200mm square-frame shelf as an example, the equipment can produce 12-15 pieces per minute, and the production speed of conventional refrigerator shelves is stably maintained at 8-10 pieces per minute—representing an efficiency improvement of over 150% compared to traditional equipment.
More importantly, the equipment’s precision control sets an industry benchmark: the bending precision is ±0.5mm, and the wire-feeding precision is ±0.5mm. The core processing error is far lower than the industry average, ensuring that the hole diameter, spacing, and bending angle of each refrigerator shelf fully comply with design standards. No subsequent manual correction is required, which significantly reduces the rework rate and material waste.
Intelligent and User-Friendly Design: Further Reducing Operating Costs
The intelligent and user-friendly design of this machine further lowers the operating costs of refrigerator shelf enterprises.
- Intelligent control: The equipment is equipped with a 32-bit high-performance control module, and mechanical movements are precisely controlled by a microcomputer program. It supports integrated operations including automatic feeding, automatic material returning, straightening and cutting, and bending and forming—no manual intervention is needed.
- User-friendly interface: The operation interface is equipped with a multi-language intelligent system (supporting English and Chinese) and adopts a dual-control mode of touch screen + physical buttons. The interface is clear and intuitive, allowing new employees to master operations after simple training.
- Efficient production change: The system has a built-in data upload and download function, which can store 4000 sets of processing data (with 300 actions per set). When switching to the production of refrigerator shelves of different specifications, there is no need to replace universal molds—users only need to call the preset program, which greatly shortens the production change time.
Durability and After-Sales Support: Providing Peace of Mind for Enterprises
In terms of durability and after-sales support, this 2D wire bending machine also reassures enterprises.
- Long service life: The core components of the equipment have undergone strict aging tests. Under normal use conditions, the service life can reach more than 10 years, enabling it to stably undertake high-intensity mass production of refrigerator shelves for a long time.
- Comprehensive after-sales service: The manufacturer provides a 2-year free warranty. During the warranty period, the professional after-sales team will respond promptly to issues such as equipment fault diagnosis, spare parts replacement, and program debugging, completely resolving the worries of enterprises.
For refrigerator shelf production enterprises, this 3-8mm 2D wire bending machine is not only an "accelerator" for improving production efficiency but also a "guardian" for ensuring product quality. With its precise hardware configuration, efficient processing capacity, and intelligent operation design, it perfectly meets the large-scale production needs of refrigerator shelves. Meanwhile, it can also be extended to wire forming processing in fields such as auto and motorcycle parts, kitchen and bathroom hardware, and daily-use hardware. If you are troubled by the low efficiency and low precision of traditional wire bending equipment, this 2D wire bending machine will provide you with an efficient, stable, and worry-free wire forming solution.
