External Truck Body Panels Roll Forming Machine: Fully Automatic Batch Production for Truck Side Panels
If you’re seeking a high-efficiency solution to mass-produce truck body side panels, our External Truck Body Panels Roll Forming Machine delivers full automation—from raw material feeding to finished panel collection. With flexible welding options and precise processing, it ensures consistent quality for truck body components, tailored to industrial production needs.
Compatible Raw Materials: Stable Input for Reliable Production
The machine is optimized to handle steel coils that meet standard truck body panel requirements, ensuring smooth material feeding and forming:
- Steel Coil Dimensions: Inner diameter of φ508mm; maximum outer diameter of φ1500mm (accommodates common coil sizes in the industry).
- Coil Weight: Maximum 10t (reduces frequency of coil replacement, improving continuous production efficiency).
- Steel Plate Thickness: 1.5 ~ 2.5mm (note: thin plates have higher strength, thick plates have lower strength—adaptable to different panel rigidity needs).
- Material Type: Q235 steel (a widely used structural steel with good ductility and weldability, ideal for truck body panels).
Full-Automatic Working Flow: Streamlined from Start to Finish
The machine follows a systematic, uninterrupted workflow to minimize manual intervention and boost production speed. Each step is designed to ensure precision and consistency:
- Automatic Feeding: Unwinds steel coils via an automatic decoiler, ensuring stable material output.
- Metal Embossing: Adds decorative or structural embossing to the steel plate (per design requirements) for enhanced panel performance or aesthetics.
- Pit Looper Storage: Temporarily stores processed material to buffer between production stages, preventing bottlenecks.
- Servo Feeding + Hydraulic Punching & Notching: Uses servo control for accurate feeding, while hydraulic systems punch holes and cut notches—critical for panel assembly.
- Secondary Pit Looper Storage: Provides another buffer before main forming, maintaining steady material flow.
- Main Rolling Forming: Shapes the steel plate into truck side panel profiles via a dedicated molding frame and gearbox system.
- Tracking Roller Welding: Performs on-line welding (rotary or laser, optional) to secure panel structures.
- Shaping: Refines the formed panel to ensure dimensional accuracy and smooth edges.
- Servo Tracking Hydraulic Punching & Cutting: Trims the finished panel to exact lengths using servo-controlled hydraulic cutting.
- Receiving Table: Collects finished panels, ready for subsequent assembly or packaging.

High-Performance Online Roll Spot Welder: Secure, Consistent Welds
The machine’s 2 sets of online roll spot welders are a highlight, designed to meet strict truck panel welding standards:
- On-Line Tracking Welding: High-power roll welders enable automatic tracking welding, boosting weld quality and operational stability. Maximum welding speed reaches 6m/min, matching production line throughput.
- PLC-Controlled Precision: All welding actions are PLC-regulated; the welding control box locks key parameters (welding current, speed) and interlocks with the entire line’s electric system—preventing errors.
- Superior Weld Quality: Welds are firm and reliable, with no obvious indentations, false welds, or burn marks. Post-welding, the joint fits seamlessly with the panel’s lap edge, meeting truck body use requirements.
- Fixed Weld Spacing: Consistent 100mm distance between two welding points, ensuring uniform structural strength across the panel.
