A two-roller Plate Rolling Machine forms flat sheet or plate into cylinders, arcs, and certain tapered shapes by pinching the material between two driven rolls and applying controlled pressure to create plastic deformation. In ZHUOSHENG’s two-roller design, the upper roll is a steel roll, while the lower roll uses a steel core with an elastic layer. As the roll gap is adjusted, the plate is lifted and partially deformed; continuous roll rotation then feeds and bends the plate progressively until the target radius is achieved.
This structure is often chosen when you want fast cycle times, consistent roundness, and straightforward operation that can be integrated into a repeatable production process with program control.
Unlike multi-roll configurations that rely on multiple pre-bending steps, a two-roller system focuses on stable pinch + continuous rolling:
Upper steel roll provides rigidity and stable geometry under load.
Lower elastic-layer roll increases frictional grip and helps “wrap” thin materials smoothly, which supports fast forming with less surface damage risk when set correctly.
Hydraulic downforce and gap control determine how much curvature is introduced per pass, while the roll rotation drives feed and bending simultaneously.
On ZHUOSHENG’s automatic hydraulic two-roller configuration, the system is commonly paired with PLC touch-screen control, supporting repeatable parameters for different materials and target diameters.
The operator confirms material type, thickness, and required diameter, then sets roll pressure, gap, and speed. On PLC-controlled machines, this is typically done via the touch screen to keep settings consistent across batches.
The plate is guided into the nip between the two rolls. Proper squaring at entry is critical: if the leading edge enters skewed, the cylinder will track sideways and create an uneven seam.
ZHUOSHENG’s design notes manual auxiliary feeding as part of the process, with controls to reduce mismatch at the joint after rolling.
As the roll gap is adjusted, the plate rises and begins plastic deformation. The rolls continue rotating so the plate is bent progressively along its length until the curvature closes into a cylinder.
For many thin-wall cylindrical parts, controlling the seam opening is a key acceptance point before welding or joining. ZHUOSHENG indicates that the joint gap after rolling can be controlled within 5–10 mm on their two-roller machine description, helping simplify downstream joining alignment.
After forming, the workpiece is removed. ZHUOSHENG highlights an automatic material return device on the two-roller machine description, which helps throughput and reduces manual handling time.
Roundness is not only about the rolls—it’s about stable pressure, consistent feed, and correct speed. ZHUOSHENG specifies that the roundness of the rolled workpiece can be within 5‰ of the rolling diameter under proper operation conditions.
Two-roller systems are often selected for speed-focused production of thin-wall cylinders. ZHUOSHENG provides a representative benchmark: about 18 seconds per piece for workpiece rolling time on the referenced two-roller description.
Stable friction is essential. If the lower roll or plate surface is contaminated, slippage increases, which can mark the surface and reduce dimensional repeatability. ZHUOSHENG explicitly notes that the lower shaft should be free of oil and dirt, and that rolled plates should avoid defects such as cracks or misalignment.
Two-roller “capacity” is not a single number. It’s a combination of thickness, width, material strength, and minimum achievable diameter. ZHUOSHENG’s own capacity guidance emphasizes evaluating these together rather than relying on one headline spec.
Here’s an example parameter set published on ZHUOSHENG’s two-roller product page:
| Parameter | Example configuration (ZHUOSHENG) |
|---|---|
| Max rolling thickness | 4 mm |
| Max rolling width | 1000 mm |
| Plate rolling speed | 10 m/min |
| Min full-load rolling diameter | 25 mm |
| Drive and control | Hydraulic + PLC touch screen |
| Main motor power | 4.0 kW |
ZHUOSHENG also summarizes typical industry ranges in their capacity discussion, including examples such as 0.8–6 mm thickness and 50–1500 mm rolling width for certain two-roller machines, and notes how minimum diameter is often tied to roll diameter guidelines.
A plate rolling machine concentrates force at the nip point, so safe operation is inseparable from stable production. In many markets, manufacturers apply general machinery safety principles based on risk assessment and risk reduction methods such as ISO 12100, which defines a structured approach to hazard identification and risk reduction for machinery over its lifecycle.
In practice, that translates into:
Guarding and safe distances around in-feed areas and transmission components
Accessible emergency stop and clear operator positioning rules
Routine checks for roll surface condition, hydraulic stability, and fastener tightness
Clean contact surfaces to prevent slip marks and inconsistent radii, aligning with ZHUOSHENG’s cleanliness notes for the lower shaft and plate condition
From a production standpoint, the value of a supplier is not only the machine layout—it’s how reliably the machine can be configured to your parts and process.
ZHUOSHENG positions its two-roller solutions around:
One-time forming for efficiency and simplified operation logic
PLC touch-screen control for repeatable rolling parameters
A supplier workflow that supports non-standard customization, documentation support, and responsive service commitments (such as response timing) as part of project delivery.
If your parts mix includes thin-wall cylinders, ducting components, or round shells where cycle time and roundness consistency matter, a two-roller configuration—properly specified—can be a high-efficiency choice, and ZHUOSHENG’s published parameters provide a clear starting point for technical alignment.
A Two-Roller Plate Rolling Machine operates by pinching the plate between two rolls, applying controlled pressure to initiate deformation, and continuously feeding the sheet through rotation until the desired cylinder or arc is achieved. The best results come from controlling entry alignment, roll gap, surface cleanliness, and speed—then matching real part requirements to capacity metrics like thickness, width, and minimum diameter. With hydraulic drive and PLC control options, ZHUOSHENG’s two-roller systems are designed to support stable, repeatable production where throughput and geometric accuracy are priorities.
