Roll Forming

The “Three-Roll Type Bending Roll” literally curves a plate in between three rolls by pressing the upper roll. Temporarily welding for finishing.

Bending is worked using a press.

A bending die is used.
Giving pressure on the steel plate

Combination Bending

To use a press, a die is required for bending the material.

Bend at a certain position of the flat plate. A die is required for bending.
Next, bend at another position as if drawing a circle. An R-forming die is required.
Gradually decreasing the diameter. A part is finished by bending a single steel plate multiple times like bending at two positions, three positions.

Roll Forming of Various Section Steels

Bending of round pipes, square pipes, flat bars, angles, H-section steels, I-section steels, and beams.
Other types of section steels are bent. Please feel free to contact us for any question.

Draw Bending

The “Draw Bending” refers to the cold bending process of pipes. This is a working technology to form a straight (round, square, etc.) pipe into a designated bending radius and angle.

Induction Bender

We can bend the steel according to your required dimensions without manufacturing a die. In terms of the ovalization factor and thinning factor, induction bender is more excellent than cold bending.

Applicable Steel Materials

Metals such as steel, stainless steel, aluminum, copper, titanium, brass, nickel, and non-ferrous metals
