Introduction and Technical Capabilities of Press Brakes
Metal forming and shaping, particularly of iron and steel sheets, is a prevalent and extensively utilized industrial production process within the metalworking domain. This process enables the fabrication of intricate components with exceptional dimensional accuracy and precision, enhanced mechanical properties, and diverse shapes with an aesthetically pleasing surface finish.
One of the most prevalent forms of metal forming is bending, which entails the permanent deformation of sheet metal along a straight line utilizing a press brake. Bending (forming) is a sheet metal forming process that finds widespread application in the production of numerous industrial products, including household appliances, construction machinery and transportation equipment, building structures, elevators and escalators, automotive components, petrochemical industries, agricultural equipment, and virtually all metal products. The bending process is instrumental in the manufacturing of components such as metal frames and enclosures, metal bodies for diverse products, metal sheets, supports and restraints, hinges, channels, and other symmetrical and asymmetrical metal parts utilized in automobiles, aircraft, vessels, and various consumer products.
Two primary types of bends are employed in the bending process: V-bending and U-bending, with V-bending being the more frequent.
In the bending process, the raw material (sheet metal) is compressed into a mold (die) by a punch (which assumes various shapes and angles) to attain the desired bend angle and shape. The bend angle is determined by the dimensions of the die opening and the depth of penetration of the punch and sheet metal into it.
Understanding the principles and theories governing the bending process is paramount for the optimal utilization of bending equipment, such as press brakes, manual and hydraulic benders. Ignorance of these principles and the inappropriate selection of equipment, including the choice of machine, punch, and die, or improper machine operation, can lead to financial losses and, in some cases, human injuries. Consequently, we strongly encourage you to explore the articles authored by experts at Dayani Machine Manufacturing, which are available on this website. By doing so, you will gain valuable knowledge and insights, and you are welcome to share your expertise and information with us through this platform.
It is crucial to recognize that several factors contribute to achieving the highest quality bend. These factors encompass the correct and uniform bend angle throughout the work area (sheet length), a suitable work surface, and the aesthetic appeal of the work. These factors encompass the type and dimensions of the tooling, the type of bending machine employed, the type of bend required, the type and quality of the material, and all play a pivotal role in determining the quality of the output.
Dayani the Great Machine Manufacturing: Press Brake Manufacturers
Dayani the Great Machine Manufacturing is a leading manufacturer of high-quality and efficient press brakes. These bending machines are capable of delivering precise and complex bends, including sequential and variable bends. The versatility of these machines enables the sequential execution of multiple bends and the repetition of the same process on various sheets, ensuring uniformity and consistency in the production of workpieces.
The advanced settings offered by Dayani the Great Machine Manufacturing allow users to save bending programs for specific products. This feature enables the recall of previously saved programs during subsequent bending processes, eliminating the need for manual adjustments and significantly reducing production time. PLC models can store up to 200 to 250 programs, while CNC models offer unlimited program storage capacity.
?What is a Press Brake and What Does it Do
A press brake is an industrial machine employed for bending sheet metal. It utilizes its specific tooling (punch and die, and their accessories) and initial settings you provide to generate uniform and repeatable bends.
By selecting the appropriate punch and die, calculating the required V-opening (a guide plate is installed on Dayani the Great Machine Manufacturing machines to facilitate this process), and making the correct machine settings (which will be provided by a Dayani the Great Machine Manufacturing expert during the purchase), you can swiftly and efficiently execute your production tasks.
The punch is securely attached to the machine’s ram via high-quality tie rods, and the ram is driven by powerful jacks manufactured by Dayani the Great Machine Manufacturing. This movement occurs in both upward and downward directions. The die is also installed on the machine table, and the desired bend is created by positioning the sheet between the punch and die and applying pressure from the hydraulic jacks.
As the ram descends, the initial speed is high, and as the punch approaches the workpiece, the speed decreases, and the force (pressure) increases.
By utilizing Dayani the Great Machine Manufacturing press brakes, you can save the bending program for a specific part and recall the same settings in the future to continue your production without the need for manual adjustments to the machine.
Types of Press Brakes
Dayani the Great Machine Manufacturing offers a comprehensive range of high-quality and powerful press brakes, designed to meet the diverse demands of various industries. Our expertise and capabilities enable us to manufacture press brakes in diverse sizes and capacities, accommodating a wide spectrum of applications.
Our press brakes are available in sizes ranging from 2 to 7 meters (width of the sheet for bending) and with capacities from 80 to 1000 tons. Our advanced machinery can be equipped with PLC systems for three-axis control or CNC systems for four-axis control and beyond. Additionally, we offer customized options to enhance usability and align with specific customer requirements.
Press brakes up to 12 and 14 meters wide (tandem) can also be meticulously designed and manufactured by our skilled factory experts upon request. Furthermore, larger or smaller sizes and capacities can be customized to meet the unique needs of each customer.
Dayani the Great Machine Manufacturing press brakes are meticulously crafted using only the finest raw materials.

How to Choose a Press Brake
Selecting the best press brake for your needs requires careful consideration of several factors:
1. Material properties:
- Pay attention to the standards declared by manufacturers, which are based on ST37 steel sheets with a tensile strength of approximately 400 N/mm².
- If you use other types of sheets, consider their tensile strength. For example, stainless steel has twice the tensile strength of ST37 steel, so the required bending force will be doubled.
2. Maximum bending length:
- If you work with different lengths, consider the maximum length and the most frequent repetition.
3. Maximum sheet thickness:
- Determine the maximum thickness of the sheets you will be bending.
4. Required bending angle:
- Specify the desired angle for your bending operations.
5. Bending edge:
- Define the required bending edge radius.
6. Future workload:
- Anticipate your needs for the next 5 years in terms of bending thickness and length.
7. Production volume:
- If you have a high production volume, consider using a slightly stronger press brake. However, if you use Dayani the Great Machine Manufacturing press brakes, this is not necessary.
Considering the above factors, you can choose the best machine with the guidance of Dayani the Great Machine Manufacturing experts.
Based on experience, it is recommended to consider 20% more capacity than your current needs to avoid problems in the future with longer or thicker sheets or possible dry sheets.
