Press Brake

For sheet metal bending, the press brake is a necessary machine. We have NC type and CNC type press brakes. At the same time, we can customize the punches and dies according to your practical use in sheet metal fabrication.

Shearing Machine

For the straight cutting of steel plate, hydraulic shearing machine is a good choice. It not only has high cutting efficiency, but also requires less investment. We have both swing beam shears and guillotine shears for your selection.

Laser Cutting Machine

In the current metal plate and pipe cutting, laser cutting machine is undoubtedly the best choice. It can not only cut various shapes, but also has small cutting gap, high precision and high cutting efficiency. Today, it is very cost-effective.
