Double Pre-pinch Plate Bending Machine Loni

Being one of the famous firms in the industry, we are decidedly involved in providing a first-class array of Double Pre-pinch Plate Bending Machines. These machines are specially manufactured to bend metal sheets into curved, cylindrical, or conical shapes with high accuracy and minimal edge deformation.

Double Pre-pinch Mechanism for Superior Edge Control

This machine features a dual pre-pinch system that allows both edges of the metal sheet to be pre-bent before the main rolling process. This reduces the need for manual trimming and helps in achieving better roundness with tight tolerances, especially useful for pressure vessels and pipe fabrication.

Precise Bending with Hydraulic Assistance

Equipped with hydraulic cylinders, the bending rolls can be adjusted smoothly to match the thickness and width of the sheet. The system provides consistent pressure across the material, making it easy to bend thick or high-tensile sheets without warping or cracks.

Three Roll Configuration with Top Drive

The Double Pre-pinch Plate Bending Machine uses a three-roll structure where the top roll is power-driven while the bottom two rolls move independently to apply pre-pinch pressure. This design offers both flexibility and control, helping in shaping round components with uniform curves.

Operator-Friendly Control Interface

These machines often include a user-friendly control panel for setting roll pressure, bending angles, and material feed speed. Operators can carry out repetitive bending jobs with precision thanks to the automatic and manual modes provided on advanced models.

Strong Build for Heavy Industrial Use

The machine body is manufactured from graded steel plates to resist deflection and vibration. The bending rolls are hardened and machined to exact diameters, ensuring a long operational life even in continuous-duty industrial environments like shipbuilding, fabrication yards, and power plants.

Suitable for Cylinders, Drums, and Flanged Sections

Double pre-pinch machines are ideal for forming cylindrical tanks, pressure vessels, drums, and flanged circular parts. Their ability to bend both edges without needing to reverse the material saves time and enhances production efficiency.

These Products Are Used in Diverse Industrial Applications

Double Pre-pinch Plate Bending Machines are widely used in commercial and industrial applications such as oil tank manufacturing, HVAC duct fabrication, trailer body construction, and storage vessel production. Their precision-bending capability makes them indispensable in the sheet metal industry.
