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 Copper Irregular Straightening Machine is designed for straightening copper bars, rods and non-round profiles whose cross-sections cannot be handled effectively by conventional round-bar straighteners. It is suitable for copper materials that require controlled correction after extrusion, rolling, drawing or other forming processes.
Copper is relatively soft and ductile compared with many structural metals. During straightening, excessive roller pressure or an unsuitable contact position can leave surface marks or alter the profile geometry. The machine therefore uses a configurable roller system to apply correction at multiple points while controlling the amount and direction of deformation.
The copper profile passes through a series of adjustable straightening rollers. Each roller applies a controlled amount of correction from a specific direction, gradually reducing bending or twisting instead of forcing the entire deformation at one point.
For irregular sections, roller contact must match the actual profile geometry. Roller spacing, alignment, pressure and correction direction are adjusted according to the section shape and deformation pattern. This is particularly important for copper because concentrated pressure can produce local dents, surface scratches or cross-section distortion.
Depending on the production line, the machine can be configured with automatic or semi-automatic feeding and integrated with upstream forming or downstream cutting and processing equipment.
Profile-Specific Roller Arrangement
The roller layout is selected according to the copper profile rather than treating every workpiece as a round bar. Contact points can be arranged around the section to suit asymmetric and custom-shaped profiles.
Controlled Correction for Soft Copper
Copper requires sufficient force to correct deformation without excessive local pressure. Adjustable roller positions and working conditions allow the correction load to be distributed across multiple contact points.
Protection of Profile Geometry
For electrical conductors, busbars and other functional copper profiles, maintaining the designed cross-section can be as important as achieving straightness. The straightening system is configured with this requirement in mind.
Suitable for Different Copper Sections
The Copper Irregular Straightening Machine can be configured for round, square, rectangular, flat and other irregular copper sections, subject to the actual material dimensions and profile geometry.
Adjustable for Different Production Requirements
Roller spacing, alignment and working parameters can be adjusted for different material sizes and deformation conditions, making the equipment suitable for multi-size production.
| Series | FR Series |
| Roller Distance | 9–1450 mm |
| Roller Arrangement | 13-1 to 9-1 configurations |
| Main Motor Power | 3–225 kW |
| Material | Copper and applicable copper alloys |
| Profile Type | Round and irregular cross-sections, depending on machine configuration |
| Configuration | Selected according to profile geometry, dimensions, deformation and straightness requirements |
The above specifications are for reference. The actual machine configuration depends on copper grade, profile dimensions, section geometry, initial deformation, required straightness tolerance and production capacity. For irregular profiles, a profile drawing or material sample should be provided before final machine selection.

Fangrong was established in 1998 and has more than 26 years of experience in straightening machines, cold drawing equipment and related metallurgical machinery. The company operates two manufacturing facilities: Dongguan Fangrong Metallurgical Equipment Co., Ltd. and Yangjiang Fangrong Machinery Co., Ltd.
FangRong equipment has been supplied to more than 10,000 customers in over 60 countries and regions. Its production range covers equipment for tube, bar and profile processing, with in-house engineering, manufacturing, assembly and testing capabilities.
For irregular copper profiles, machine selection is based on the actual material and deformation condition rather than only the nominal diameter. FangRong can evaluate profile drawings, samples and production requirements to determine the appropriate roller arrangement and machine configuration.
Each Copper Irregular Straightening Machine is engineered according to the customer's material and production requirements. The main production stages include:
Engineers review the copper grade, profile drawing, dimensions, material length, initial bending or twisting, required straightness and expected output.
The machine frame, roller arrangement, transmission system and control configuration are selected according to the actual profile and correction requirements. Special attention is given to roller contact positions for irregular sections.
Key machine components are precision machined before assembly. Straightening rollers are processed according to the required working geometry and surface condition.
The frame, rollers, drive system and electrical components are assembled and aligned. Roller positioning and machine operation are checked before testing.
Testing can include:
- Roller alignment inspection
- Machine running test
- Straightening performance test
- Electrical system inspection
- Continuous operation test
FangRong provides installation guidance, operator training, technical support and a standard one-year warranty. Spare parts and troubleshooting support are available for continued operation after delivery.
ISO 9001:2015 — Quality management system certification, Certificate No. UQ231211R1.

The machine is prepared for international shipment after final inspection and testing. Packaging is selected according to machine size, transportation method and destination to protect the equipment during handling and transit. Special tooling, spare parts and auxiliary equipment can be packed separately when required.
1. How is the roller arrangement selected for an irregular copper profile?
The arrangement depends on the copper grade, cross-sectional geometry, dimensions, initial bending or twisting and required straightness. For asymmetric sections, the roller contact points must be positioned carefully to correct the deformation without changing the functional geometry of the profile. A profile drawing and material sample are useful for engineering evaluation.
2. How do you prevent the rollers from marking soft copper?
Copper is more susceptible to indentation and surface damage than many harder metals. Roller geometry, contact area, alignment and correction pressure therefore need to be matched to the material. The objective is to distribute the correction load instead of applying excessive pressure at a single contact point.
3. Can the Copper Irregular Straightening Machine correct both bending and twisting?
Yes, the machine can be configured for different deformation patterns. However, bending and twisting require different correction directions and roller contact conditions. For a heavily twisted or asymmetrical profile, the final roller arrangement should be determined from the actual deformation rather than from dimensions alone.
4. What information is required for a quotation?
Please provide the copper grade, profile drawing or sample, cross-sectional dimensions, material length, initial deformation, required straightness tolerance and target production capacity. If several copper profiles will share one machine, provide the complete size and profile range so the working range and tooling can be evaluated.
5. Can one machine process different copper profile sizes?
Yes, provided the profiles fall within the machine's working range and the roller system can be adjusted or equipped with suitable tooling. If the cross-sections differ substantially, FangRong will evaluate whether interchangeable tooling or a dedicated roller configuration is more practical for production.
6. What are the lead time, warranty and after-sales services?
Standard machines typically require 30–60 days after order confirmation. Customized equipment may require additional engineering and testing time. The standard warranty is 12 months, with installation guidance, operator training, technical support and spare-parts service available according to the project agreement.
