Types of Bending Machine(Cold Bending): Press Brake, Rotary, Rolling, and Stretch Bending Machine

CNC Hydraulic Bending Machine
Cold roll equipment

BIT has been fabricating a broad range of Cold Roll Equipment for over 30 years. Bending machine product types are PBH Hydraulic Section Bending Machines, CNC Aluminum Bending Machines, PR Hydraulic Plate Bending Machines, PBT CNC Pipe Bending Machines, PSF Stretch Forming Machines, and PRF Roll Forming Machines.

Definition of Bending Machine?

A bending machine is used to form a metal sheet or profile into a predetermined shape by applying force to them, this then causes such metal profiles to bend at an angle to form a particular shape.

What types of bending machines?

Different types of bending machines are used for different metal bending processes. They are Brake Press/Metal Sheet Bending Machines, Metal Shearing Machines, Sheet Metal Folding Machines, Section Bending Machines/Profile Bending Machines, Plate Rolling Machine, Pipe/Tube Bending Machine, Stretch Forming Machine, Roll Forming Machine, and Punch Press.

Cold Bending Equipment

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.

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.

w24s profile bending machine

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.


PBA Aluminum Bending Machine

Up to 15 Independent Controllable Servo Axes. CNC Aluminum Profile Bending Machine;
Photoelectric positioning. Three-dimensional. CNC control. Accuracy is as high as ≤0.01mm. 
Can be bent in various shapes (3-D graphics, C-shaped, U-shaped, full circle, ellipse, multiple radii combination shapes, etc.)


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.


Rotary 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.

cnc pipe bending machine

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 Stretch Bending Machine (also named Strech Forming Machine, and Profile Stretch Press) can be divided into rotary type Stretch Bending Machine and double arm type Stretch Bending Machine, and various special stretch bending machines, such as special stretch forming machines for shower rooms, special forming bending machine for train roof beam, and special stretch forming machine for the elevator.

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.


Hydraulic Press Brakes
Hydraulic Press Brakes

A press brake is a machine used for bending sheet metal and metal plates, most commonly sheet metal. It forms predetermined bends by clamping the workpiece between a matching top tool and bottom die.

A CNC press brake is referred to as a 3 axis machine which is found to be accurate, automatic & has fast back gauge. This is known to be one of the perfect tool which is used for fulfilling the precise bending requirement. These are the ones which are known to be highly user-friendly and are found offering cost-effective solutions as per the requirement of the various industries. Each section of the machine is found to be ready in order to provide the best support while operating. These machineries are specially designed in order to fit all the precise bending requirement at a very low investment comparatively.

roll forming machine

Well-suited for customized or standard shape production, cold roll forming is a simple process ideal for even the most complex shapes. It is a flexible, responsive, and cost-effective alternative to extruded press braking and stamping.
