Cold bending, roll and stretch forming machine

Bending Machine
Cold roll equipment

BIT has been fabricating a broad range of Cold Roll Equipment for over 30 years. Products include PBH Section Bending Machine, CNC Aluminum Bending Machine, PRH Plate Bending Machine, PBT CNC Pipe Bending Machine, PSF Stretch Forming Machine, and PRF roll forming machine.

The 3-roll or 4-roll section bending machine and plate bending machine is the industry workhorse. The machine has 3-4 rolls hydraulically driven rolls in a triangular configuration.

PBH Section Bending Machine

Bending various metal profiles (including stainless steel).
Powerful bending ability can bend tubes, pipes, round & solid square & flat bars, angles, tee sections, H & I beams, and U channels to over 180 degrees and into circles or arcs, and is often chosen to create circular pieces.

4-roll plate bending machine

PBR Plate Bending Machine

A Plate Bending Machine is a device for the radial forming of flat sheets. Its works similarly to a Profile Bending Machine. However, its design is much simpler.
PBR Plate Rolling Machines are engineered for safe operations and unparalleled maximum flexibility while offering the latest in features and advanced technology. Our PRH CNC Plate Bending Machines will save you money.

cnc pipe bending machine

Rotary bending perhaps is one of the most popular and effective ways of creating a precision bend. Rotary benders, have many advantages over conventional wipe bending methods.

PBT CNC Tube Bending Machine (Pipe Bending Machine) has capabilities such as maximum repeatability and detailed accuracy, which reduce set-up times and reduce scrap.

stretch forming machine

The PBF series is the strongest Stretch Forming Machine series ever made. Our stretch forming machines allow the manufacture of large parts, for maximum industrial productivity.
PBF Stretch Forming Machine adopts full hydraulic control and can cold-form (cold bending) various steel pipes, square tubes, H-beams, I-beams, channel steels, angle irons, flat irons, and aluminum profiles with a section below 500mm.

What is cold bending?

Glossary: The bending of metal shapes by cold working at ambient temperatures.
Cold bending, as the name suggests, bends the workpiece in a cold state.
