Straightener/Leveling Machine
Straightener/Leveling Machine
The Straightening machines (coil straighteners / leveling machines) from YouYi are engineered for precise coil leveling of stainless steel, aluminum, copper and carbon steel strips. Available models cover thickness ranges from 0.1 mm to 6 mm and strip widths up to industry-standard sizes, enabling stable feed-in to downstream feeders and stamping lines.
Precision straighteners go beyond basic flatteners by eliminating coil set and residual stress that simple leveling cannot resolve. Using small-diameter work rolls supported by back-up rollers, they produce consistently flat strips with minimal internal stress. Flat parts remain flat, and round parts maintain their true geometry.
| Item | SNL Series (Precision) | SFL Series (High-speed) | HCL Series (Heavy-duty) |

| Applicable thickness (mm) | 0.1 – 0.6 | 0.2 – 1.2 | 1.0 – 6.0 |
| Max strip width (mm) | 1200 | 1500 | 2000 |
| Roller count | 8–12 | 9–13 | 7–9 |
| Adjustment method | Manual/Electric | Electric stepper | Hydraulic + worm gear |
| Max line speed (m/min) | ≤ 50 | ≤ 80 | ≤ 30 |
| Control system | PLC | PLC + HMI | PLC + Servo |
Our steel coil straightener uses precision straightening rolls to perform fully automatic straightening, while the cutting process is completed through a hydraulic shearing system. One operator can manage multiple machines, with a maximum straightening speed of up to 6 m/min, ensuring high production efficiency. The cutting length is accurately controlled by a PLC system, enabling fully automated operation and significantly reducing labor costs and human error. This steel coil straightening equipment provides the metal door industry with a high-quality and efficient solution for steel coil and sheet metal leveling.
Q: How do I choose the right straightening machine for my stamping line?
A: Provide material type, thickness range, strip width, required feed accuracy and target line speed. We will recommend the best series and roller configuration for your process.
Q: What warranty and certifications do you provide?
A: Our machines are manufactured under ISO 9001 practices. Electrical components use reputable brands; standard warranty is typically 12 months—details provided in the sales agreement.
Q: Can you perform trial runs with our coil material?
A: Yes. Send sample coils or provide material data and we can run sample flattening and share results.

SNL Type Single/Two stage Precision Straightener (Thickness: 0.1-0.6mm)
SNL Type Precision Straightener is designed for leveling thin coil materials from 0.1mm to 0.6mm. Available in single-stage and two-stage structures, it ensures high precision and surface protection for stainless steel, copper, and aluminum strips
GJ Type High precision straightener (Thickness: 0.0.5-0.6mm)
High-Precision Design: Engineered specifically for stamping medium-thin materials requiring micron-level accuracy.
SFL Type precision straightener (Thickness: 0.2-1.2mm)
This series of straightening machine is specially designed to straighten thin stainless steel, copper sheet, iron sheet and aluminum sheet and other thin materials, which can achieve perfect leveling effect
HCL Type Thick Plate straightener (Thickness: 1-6mm)
The leveling adjustment mechanism integrates a compact worm gear and worm wheel system, ensuring smooth torque transmission with reverse self-locking capability.
FJS Type high-speed straightener (Thickness: 0.3-1.5mm)
The precision-leveled material is transferred to downstream feeders via an S-shaped guiding system.
FAQ
Q: How do I determine the right feeder size for my production line?
A: The feeder size depends on the material width, thickness, and feeding step distance required by your stamping press. Choosing the correct specifications ensures smooth operation and prevents feeding errors or misalignment.
Q: What factors should I consider when choosing a servo feeder machine?
A: When selecting a servo feeder, key factors include feeding accuracy (±0.05mm or better), maximum feeding speed (e.g., 20m/min), material compatibility (stainless steel, aluminum, etc.), load capacity, and control system (PLC or touchscreen). Ensure the machine matches your stamping process requirements.
Q: How long does it take to receive the feeder machine after placing an order?
A: Lead time for delivery typically ranges from 4 to 8 weeks depending on customization, production schedules, and shipping location. Once your order is confirmed, we will provide a more precise delivery estimate.
Q: What are your payment terms?
A: We accepts T/T payment, 30% deposit and 70% balance before shipping
Q: How often should I perform maintenance on my servo feeder machine?
A: Routine maintenance should be conducted weekly for basic cleaning and lubrication, while a more thorough inspection should be done monthly to check for wear on rollers, belts, and electrical components. A full servicing is recommended every 6-12 months depending on usage intensity.
Q: What are the most common issues with feeder machines, and how can I troubleshoot them?
A: Common issues include misalignment, inconsistent feeding accuracy, or motor failure. Check for loose bolts, dirt buildup, or software calibration errors. If problems persist, refer to the user manual or contact technical support.
Q: Do you provide on-site repair services if my machine breaks down?
A: Yes, we offer on-site repair services for major issues, along with remote troubleshooting support for minor problems. For urgent cases, we can dispatch a technician within 24-48 hours, depending on your location.
Q: What's the package of your coil feeding machines?
A: For the coil feeding equipment that go LCL shipping, We will use plastic films wrap on the equiment, and then fix it into a wooden box.
For the large coil lines that go FCL shipment, We will fix each part with ropes on the shipping container and then wrapped them with plastic films.
