Bending of plates uses work rolls to bend the sheet into shapes, which can form cylindrical parts, tapered parts and other parts of different shapes.
The working principle of bending of plates is to move the work roll through the action of hydraulic pressure, mechanical force and other external forces, so that the sheet is bent or rolled into shape.
Bending of plates can process elliptical parts, arc-shaped parts, cylindrical parts and other parts according to the rotation movement and position changes of work rolls of different shapes.
A common question regarding steel plate rolling is whether the raw material, the steel blank, should be cut to length or provided with extra material to be trimmed during and/or after the rolling process. Another question related to the blank… Read More »Pre-bending of the heavy plate with a 3-roll plate roller

VARIABLES IN SHEET METAL BENDING PROCESS
While sheet metal gauges run from 0.005 to 0.249 inches thick, aluminum and steel plate thicknesses start at 0.250 in. and go all the way up to 13 in. or even more. Likewise, plate steel varies in strength from mild varieties to some very high-strength materials.
When it comes to very thick or high-tensile-strength material, traditional rules for determining minimum bend radii, minimum p
Rotary Bending ELECTRIC ROTARY DRAW BENDING Electric rotary draw bending uses the same process as the hydraulic method, but allows faster setup. The bends also are more accurate and easily repeated because angles and rotations can be automated in a machine’s programmable logic… Read More »Rotary Bending and roll-bending the metal profile
What is rotary bending? 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. Rotary Bending is accomplished by bending the Pipe or… Read More »Principles of Rotary Draw Bending
In the absence of a professional profile bending machine (also called angle bending machine or section bending machine), we can use a 3-roller plate bending machine to bend angle iron.
High efficiency! 2-roller plate bending machine generally can reach 100-350 pieces/h, up to 1000 pieces/h.The parts have high precision & good surface quality.
