FAQ

All specifications are provided by our engineering team based on actual machine configurations and production experience.

We offer a complete range of CNC press brakes for sheet metal bending, including electro-hydraulic synchronous press brakes, torsion bar press brakes, tandem (dual-machine) press brakes, and customized special-purpose press brakes.
Our main series include PSB, PSM, PSN, PSD, PSA, and PSS, covering light-duty to heavy-duty industrial applications.

Press brake tonnage depends on material type, material thickness, bending length, and die opening.
As a general reference:

Tonnage ≈ (650 × S² × L) / V

Where:

  • S = material thickness (mm)

  • L = bending length (m)

  • V = die opening (mm)

Our engineers can calculate the exact tonnage and recommend the most suitable model based on your actual production needs.

Electro-hydraulic synchronous press brakes use servo valves and closed-loop control systems to achieve higher accuracy, better repeatability, and stable synchronization, making them suitable for precision and heavy-duty bending.

Torsion bar press brakes use mechanical synchronization and are more cost-effective, ideal for standard bending operations with moderate accuracy requirements.

Our CNC press brakes can achieve:

  • Slider positioning accuracy: ±0.01 mm

  • Bending angle accuracy: ±0.1° (depending on configuration and tooling)

Accuracy may vary based on material properties, tooling, and operator settings.

Our press brakes are suitable for bending a wide range of materials, including:

  • Mild steel

  • Stainless steel
