Multi Roll Leveler for 0.08-1 mm Copper Strip in Electrical Applications
Copper strip for electrical applications is thin, soft and unforgiving of shape defects, because any residual stress turns into distortion during stamping. This leveler is configured for 0.08-1 mm copper, where roll diameter and setting precision matter more than raw force.
- Copper strip thickness 0.08-1 mm
- Q235A welded open frame
- Hydraulic servo system with sensor feedback
- Aimed at electrical and electronic component production
Key Benefits
What thin copper demands from a leveler.
Shape Control On Thin Soft Metal
Multi roll leveling corrects plate shape on strip as thin as 0.08 mm, where a coarse roll arrangement would simply mark the surface.
Settings Matched To Incoming Strip
Work rolls are pre adjusted to the incoming thickness and straightness, which is essential when copper coil quality varies.
Stable Feed For Stamping
Flat, stress relieved copper strip behaves predictably in the press, which protects tooling and yield.
Where It Is Used
Applications.
- Electrical component production
- Electronic connector and terminal stamping
- Copper strip processing lines
- Automotive electrical parts
Who It Is For
- Copper strip processors
- Electrical and electronic component manufacturers
- Stamping plants feeding from copper coil
- Buyers replacing a leveler that marks thin strip
Problems It Solves
- Shape defects in thin copper strip
- Distortion appearing during stamping
- Surface marking from unsuitable roll arrangements
- Inconsistent flatness between copper coil suppliers
Technical Features
Machine composition.
Multi Roll Configuration
The multi roll arrangement applies controlled bending suited to thin gauge copper.
Hydraulic Servo Control
The hydraulic servo system with sensor devices holds roll position precisely for soft material.
Rigid Open Frame
The Q235A plate frame, continuously welded in an open structure, gives rigidity without excess mass.

Manufacturing Process
Material Study
Copper alloy, gauge band, width and incoming flatness set the roll configuration.
Frame Manufacturing
The open frame is welded, stress relieved and machined.
Roll Set Production
Small diameter work rolls and their support rolls are produced and ground.
Assembly And Test
Hydraulic response and roll parallelism are verified before shipment.
Quality Control
- Frame machining inspection
- Roll surface finish verification for copper contact
- Hydraulic servo response test
- Roll parallelism measurement
Customization Options
- Gauge band and width to your copper programme
- Roll diameter for the thinnest gauge you run
- Surface specification to avoid marking soft copper
- Interface to your existing line controls
Use Guide
- Keep roll surfaces clean, copper transfers easily
- Set leveling depth from measured incoming flatness
- Use lower tension settings than steel practice
- Inspect roll surfaces whenever strip marks appear
How It Compares
Against other leveling options for copper.
| Steel strip levelers | Roll diameter and settings are chosen for thin soft copper rather than carried over from steel practice. |
|---|---|
| Levelers without servo control | Hydraulic servo positioning holds fine settings that thin copper needs. |
| Accepting coil flatness as delivered | Leveling in house removes the variation between copper coil suppliers. |
