Level Medium-to-Thick Coil Before Stamping

A thick plate straightener removes coil-set curvature before the press. The Jingcui BTL Series handles material from 1.0 to 6.0 mm in widths up to 1000 mm. It feeds a flat, stable strip into your stamping line.

This heavy duty straightener uses offset upper and lower rollers. They apply reverse bending force to release internal stress. The result is a consistently flat band ready for accurate, repeatable forming.

What Is a Thick Plate Straightener?

A thick plate straightener flattens coiled metal before stamping. Coiled stock carries a natural curvature from winding. The machine bends the strip in the opposite direction through a series of offset rollers.

This reverse-bending action cancels the coil-set. It also relieves residual stress in the material. The BTL Series delivers that correction in a single, continuous pass.

Home Appliance Manufacturing: Outer casings, refrigerator panels, washing machine cabinets, and air conditioner backplates.
Automotive Stamping & Shearing: Body panels, chassis reinforcement plates, and structural components.
Heavy Hardware & Electrical Enclosures: Server racks, elevator doors, distribution boxes, and industrial cabinets.
Compatible Materials: Cold/hot rolled steel, galvanized sheets, as well as aluminum and galvalume sheets (GI/GL), aluminum plates, and galvalume steel sheets (tensile strength up to 400 N/mm², yield strength up to 275 N/mm²). — within the range of the EN 10025 structural steel standard.

Key Features

Thick-Plate Capability

The BTL Series covers 1.0 to 6.0 mm material. A and B types let you match the machine to your plate gauge. This thick plate straightener handles medium and heavy stock with confidence.

Reverse-Bending Straightening

Offset rollers apply controlled reverse bending. This removes coil curvature and internal stress in one pass. The output strip stays flat from head to tail.

Intelligent Control

Feed distance and speed are customizable. PLC control adapts the straightener to your production rhythm. Operators change settings quickly between jobs.

Rigid, Reliable Frame

Power is staged by width for adequate straightening force. The robust structure resists vibration during heavy stock. Frequency-converter speed control keeps the strip stable.

Line Integration

The BTL thick plate straightener works inside a full straightener line. Pair it with a servo or NC feeder and a coil decoiler to form an automated stamping system.

FAQ

What thickness can this thick plate straightener handle?

Type A covers 1.0 to 4.5 mm. Type B extends to 1.0 to 6.0 mm. Width ranges from 200 to 1000 mm by model.

Which materials does it straighten?

It handles steel, galvanized steel, aluminum, stainless steel, and copper. High-strength stock may reduce effective capacity, so confirm at selection.

Can it run in an automated line?

Yes. The BTL Series integrates with decoilers, feeders, and presses to build a complete stamping line.

Is the feed distance customizable?

Yes. PLC control allows you to set feed distance and speed to match your process.
