What is Plate Bending/Rolling? Everything You Need to Know is here

Updated: Dec 8, 2023

You must have seen ships, rockets, oil tanks, windmills, and several other large structures around you or on trips. If you are as curious as I am, you may have always thought about how these large structures are made. For such large metal structures to be made in the desired shapes, metal Plate Bending/Rollings are installed at the workshops and factories.


Plate Bending/Rolling machine operators put the metal plates between the rollers in the machine and set the bending force, which results in bending the sheet in the desired manner. Therefore, if you are planning to enter the metal Plate Bending/Rolling industry, it is necessary to learn what it is, why it is performed and how one can perform Plate Bending/Rolling.


Let’s understand Plate Bending/Rolling in detail and also discuss how it is performed using different types of machines.


What is Metal Plate Bending/Rolling?


Metal Plate Bending/Rolling is a process of putting the metal plate into a Plate Bending/Rolling/rolling machine and passing it through the machine. Once the attributes such as the bending force and others are set, the desired shape can be achieved.

As you can see in the above image, the metal plate is between the top and bottom roller. Both rolls rotate at different RPMs and put force on the metal plate to bend/roll it. Yet, this is not the whole process. Let us tell you more about how a metal Plate Bending/Rolling/rolling machine works.


How Does a Metal Plate Bending/Rolling/Rolling Machine Work?


There are 4 crucial steps one must follow in order to achieve desired metal plate shape through a metal Plate Bending/Rolling/rolling machine.

  • Setting bending force according to the desired radius

  • Placing the metal plate on the table to maintain uniform bending/rolling

  • Pre-Pinching/Pre-Bending the tails of the metal plate

  • Passing the metal plate through the Plate Bending/Rolling/rolling machine


Step 1: Setting Bending Force on the Plate Bending/Rolling Machine

A bending operator will first assess the workload of the Plate Bending/Rolling/rolling machine. Once they are through the assessment, they decide on the bending force to be applied on the metal plate to bend/roll the machine at desired ID or OD (Inside Diameter or Outside Diameter).


A decision on ID or OD is necessary since that is the result.


Step 2: Placing the Metal Plate on the Table to Restrict Unwanted Movement

When the operator puts the metal plate on the table, it limits the movement of the plate in an unwanted direction. This is necessary since a moving metal plate would be mis-bent during the process.


Step 3: Pre-Pinching / Pre-Bending before Commencing the Bending Process

Pre-pinching or Pre-bending is the process of bending both the tails of the metal plate at the initial stage to achieve the desired radius at tails during the bending. It also helps the operator do minimal process post-bending.


Step 4: Bending the Workpiece through the Metal Plate Bending/Rolling Machine


Now that the metal plate is on the stand with pre-pinching or pre-bending successfully achieved, the operator can place the metal plate between the top roll and the bottom roll(s). The bending process is crucial, and having an experienced operator is helpful for the workshops since Plate Bending/Rolling/rolling machines are a major investment.


Types of Machines used for Performing Plate Bending/Rolling Operations

All around the world, several industries such as shipbuilding, metal fabrication, wind energy, earth moving, metal structures, rocket shell making, oil tanks, tubes and pipes, and thousands of others utilize metal Plate Bending/Rolling machines to make varying sizes of equipment and metal structures.


These are the types of Plate Bending/Rolling/rolling machines that these industries use for performing their Plate Bending/Rolling/rolling operations:


All above types of machines can be classified into two types based on their guideway type:


  • Linear Guideway Plate Bending/Rolling machine

  • Swing Guideway Plate Bending/Rolling machine


Different industries require different machines according to the workload they want the machine to handle. The choice of the machine also depends on the precision levels and majorly on the skillset of the operators.
