Overview Of Sheet Bending Machines
Sheet bending machines aka sheet metal bending
machines are used in automobile, aircraft and
similar manufacturing industries. Before we get
to know about the use of these machines in these
industries, lets ?nd out what exactly is this
process and what are the di?erent types of sheet
metal bending machines available, their
speci?cations, applications, advantages and
disadvantages if any. Also, we will check on the
factors to be considered while purchasing a sheet
metal bending machine.

What is Sheet Metal Bending? Bending is a widely
used technique in metal fabrication. It helps
transform metals to angular shapes. With sheet
metal bending, the metals can be deformed into
di?erent shapes through the process of

Sheet metals are normally materials with
thickness below 3mm. and the laser cutting
process and bending operations can be done easily
on these. What makes the sheet metal bending
method more widely accepted over other methods
is the ?exibility it o?ers on being able to use
on a wide range of materials, material thickness
and the parts that can be produced no matter how
complicated it is. The most common applications
of sheet metal bending come in automotive,
furniture, household appliances, industrial
equipment and much more. This method is normally
done in combination with bolts or rivets or a
welding process. This o?ers greater ?exibility
because parts of varied thicknesses can be
connected to each other depending on their use.
Other factors that can contribute to the
adaptability and ?exibility of sheet metal
modules are countersinking, threading, boring,
chamfering etc.
With the arrival of sheet bending machines and
CNC cutting machines, parts are able to be
manufactured in one module. In the past, it
required welding or any other joining methods to
be involved. Advantages of Sheet Metal Bending
Machines The main advantage of sheet bending
machines would include speed, accuracy, less
weight, cost e?ectiveness, little tooling and
reduced parts. Lets look in detail at the
advantages below. Manufacturing Speed Mass
production of sheet metal parts in a considerably
reduced time is possible with these machines.
This is achieved greatly because there is no
requirement of tooling and greater amount of
automation is possible. Accuracy Extremely
accurate sheet metal parts can be manufactured if
careful considerations are made during the
design phase especially with cutting holes
within 0.1mm by laser. Fewer Post
Processing Several processes are to be undergone
to ?nish a part in welding. Its because of the
heat that can distort the metal which will
require straightening and welding splatters have
to be removed through very time-consuming and
laborious grinding and polishing tasks, but in
the case of opting for sheet metal bending,
there is no such requirements, and the parts are
ready for dispatch from production. Light
Weight Owing to the complicated bends o?ered,
strength and rigidity are gained by using very
few materials which in turn reduces the weight of
the parts. This will become advantageous in
every phase of the supply chain including
material transfer. Reduced Cost And No
Tooling With the advent of technology, sheet
metal bending cuts down manual labor involved in
the production of parts. CNCN processed tooling
helps manufacture parts with considerably less
skilled workers in a short duration resulting in
reduced end user cost.

Since sheet metal bending machines have a line of
general tools ,, the need for specialized
tooling is eliminated there. This in turn reduces
the
cost for tooling and saves time as there is zero
necessity of complicated tooling to be
manufactured, tested and adjusted if
required. Reduced Parts Manufacturing an element
from a single part of materials other than from
multiple components with joints will considerably
reduce the errors, breakdown points, time as
well as complication in procurement. Disadvantage
s of Sheet Metal Bending Like any other process,
Sheet metal bending also comes with some
downsides. Lets check it in detail. Thickness Th
e thumb rule in sheet metal bending process is
that the more the thickness of the materials,
the greater the bending radius. Hence tight
bends are usually done on thin sheet metals.
Also, if you bend extremely thick materials, it
will result in bulging of materials. Uniform
Thickness Due to the reason that parts are made
from a single component of metal, the thickness
will be the same for separate ?anges. It means
the whole part must be designed in that
thickness. Manufacturing Cost When dealing with
low and medium volumes of job, sheet metal
bending is the most economical process. With
further increase in volume, it has been noted
that the stamping process is much better. As
components must be processed one by one. When to
choose Sheet Metal Bending process? This method
is mostly used where tiny to large parts with
straight angles are required. Also, it is used
to achieve certain geometry shapes and where
multiple bends are required. If the precision
level of this process is /- 0.18mm and the
thickness of the metal used is from 0.5mm to
20.0mm with no custom tooling required, this
method is chosen. This method is suited for small
to medium quantity jobs like 1 to 10,000 units
and the lead time is less than one hour. Sheet
Metal Bending Machine Types There are di?erent
types of sheet metal bending machines available
in the market with di?erent con?gurations. There
are highly complex models that are being used
for industrial purposes for bulk processing and
those used in small workshops catering to low
production. Some of the widely used sheet metal
bending machines are Press brakes, Shearing
machines, Bending rollers and Power press metal
forming. Applications Press brakes, being the
most widely used machine for sheet metal
bending, helps bend sheets and plates into
custom-made shapes. There are di?erent types of
press brakes available Manual, Pneumatic as
well as Hydraulic versions are employed in
industries depending upon the requirement. Metal
forming works like bending, curling,

bottoming, angled shaping, seaming and hemming
are mostly done with Press brakes. By making use
of respective dies.
Bending Rollers are used to bend and straighten
parts and metal covers of pressure vessels,
converters and boiler tanks. Mechanical and
hydraulic shears are utilized for sheet metal
cutting. Large sheets, plates and bars of
metallic and nonmetallic materials are cut
accurately with the help of these shearing
machines. Power press is the most excellent
bending machine which o?ers to cut metal cutting
accurately, this method is also used for bending
and shaping jobs for bulk jobs. Where to buy
Sheet Metal Bending Machines in UAE? Be it any
machine, careful considerations have to be made
while choosing the brand, the quality o?ered and
the service standards. When you purchase
machines by choosing a supplier based on the
above three factors, you will feel a lot more
relaxed even if any mechanical issues come once
the machine starts operating. Companies like YES
Machinery o?er you the best brands of sheet metal
bending machines from Europe. They make sure
they deliver the best quality at the best price
and also you will have a hassle-free after-sales
service with them. So dont forget to keep these
things in mind when you purchase your sheet
metal bending machines. Category Machines
