Frequently Asked Questions

How to choose the capacity of a press brake?

Select based on material thickness, tensile strength, and bending length. A general rule: 80% of machine capacity should match your typical workload for optimal efficiency and tool life.

How to choose the V-die for a press brake?

The V-opening should be 8-10 times the material thickness for mild steel. For harder materials, use a wider V-die. Always refer to the machine’s tonnage chart to avoid overloading.

How does a CNC press brake work?

A CNC press brake uses servo-hydraulic systems controlled by a computer to precisely position the ram and back gauge. Programs store bending sequences, angles, and tooling data for repeatable, high-accuracy results.

How to solve barrel defect during roll bending?

Barrel defects occur due to roller deflection. Use machines with crowning systems or pre-load the top roller to compensate. Ensure proper alignment and gradual pressure application.

What industries use SINOBENDER machines?

Our machines are used in shipbuilding, petrochemical, bridge construction, pressure vessels, wind energy, automotive, and general metal fabrication industries worldwide.
