Sheet Bending Basics

Sheet bending is an effective way to make products with different shapes used for different processes.  It is an operation that includes using pressure and force to change the shape of a sheet.  Normally done to achieve the desired shape or form that is necessary for the manufacturing process.  When the external force is applied it alters only the external features of the material.  While being conducted this does not change the parameters of the length or thickness of the sheet.  With the sheet having malleability it allows for sheet bending to be possible to undergo various shaping processes.  

Applications of Bend Sheet Metal

When it comes down to metal production sheet metal bending is one of the essential processes.  For example, the automotive industry relies on it heavily to produce cars that work with their designs.  Such as making big engine parts or even little replacement parts to the same engine.  While there are many processes when it comes to metal bending they all follow standard techniques to ensure precision across its production.  

Sheet Metal Bending Methods

The end goal for all sheet metal bending is the same.  It is to transform a sheet into a desired shape or form.  However, they do differ in operation as there are factors that go into each bending with different materials. Understanding the factors such as thickness, size of the bend, metal bend radius, and the intended purpose will help you determine the method needed. 


This is the most common method of sheet bending.  When conducting the v-bending method there are two components that allow the sheet to be bent.  The punch and v-die allow you to bend the sheet metal at the desired angle you want.  During the process the punch will press on the metal that is placed over the v-die.  The angle is determined by the pressure point of the punch.  There are three common bends for v-bending, bottoming, coining, and air bending.  

 Roll Bending 

As the name suggest this method is used to bend metals into a roll or curved shapes.  This process utilizes a hydraulic press, a press brake, and three sets of rollers. This method is very useful when looking to make cones, tubes, and hollow shapes.  This is helpful as they take advantage of the distance between rollers to make the desired bends and curves.  


In terms of the principle applied, u-bending is very similar to v-bending.  They utilize the same instruments and processes.  The only difference being the outcome of shape. U-bending has become very popular even though other methods can produce similar shape flexibly.  

Wipe Bending 

Wipe bending is another method that is effective for bending sheets or metal edges.  The process is dependable on the wipe die.  The metal must be properly pushed on to the wipe die for it to work.  The wipe die can determine the inner radius of the metal bend.  

Rotary Bending

This bending method has an upper hand compared to v-bending or wipe bending.  It is more elegant and will treat the metal nicer.  Rotary bending is great for not leaving behind scratches on the sheet.  This method is ideal when looking to bend metals into sharp corners.  Especially anything that needs to be bent beyond 90 degrees.
