Types of Press Brakes
Diani Heavy Machinery started manufacturing its press brakes in 1983. Over time, the range of press brakes produced by Diani Heavy Machinery has expanded, so that today, various types of press brakes are produced in three categories: light, semi-heavy, and heavy. All press brakes manufactured by Diani Heavy Machinery, including light, semi-heavy, and heavy press brakes, are available in two models, CNC and PLC, depending on customer requirements. The following sections describe the specifications and features of each type of press brake manufactured by Diani Heavy Machinery.
- Light Press Brake by Diani Heavy Machinery
The main characteristic of the press brakes manufactured by Diani Heavy Machinery is their tonnage or pressing power. All press brakes with a power of less than 150 tons are classified as light press brakes. The main models of light press brakes manufactured by Diani Heavy Machinery in this category are described below.
| Model | Power (Ton) | Maximum Bending Length | Approximate Weight | Ram Stroke |
| HB 1505 | 50 | 1550 mm | 3 ton | 150 mm |
| HB 2008 | 80 | 2050 mm | 5 ton | 180 mm |
| HB 2508 | 80 | 2550 mm | 5 ton | 180 mm |
| HB 2510 | 100 | 2550 mm | 6 ton | 200 mm |
| HB 3010 | 100 | 3050 mm | 7 ton | 200 mm |
| HB 3012 | 120 | 3050 mm | 8 ton | 200 mm |
The HB3010 and HB3012 models are among the most commonly used press brakes manufactured by Diani Industrial Machinery.
- Semi-Heavy Press Brake by Diani Industrial Machinery
Press brakes with a tonnage between 150 and 250 tons, manufactured by Diani Industrial Machinery, are referred to as semi-heavy press brakes. These machines have greater power (tonnage) and weight compared to the light press brakes, and their structures are more robust than the light models produced by Diani Industrial Machinery. The table below displays some of the best-selling semi-heavy press brakes manufactured by Diani Industrial Machinery.
| Model | Power (Ton) | Maximum Bending Length | Approximate Weight | Ram Stroke |
| HB 3015 | 150 ton | 3050 mm | 9 ton | 220 mm |
| HB3020 | 200 ton | 3050 mm | 12 ton | 250 mm |
| HB 3025 | 250 ton | 3050 mm | 13 ton | 250 mm |
| HB 4020 | 200 ton | 4050 mm | 13.5 ton | 250 mm |
| HB 4025 | 250 ton | 4050 mm | 19 ton | 250 mm |
Large industries and workshops that require bending sheets with a thickness greater than 5 millimeters typically use the semi-heavy press brakes produced by Diani Industrial Machinery. This category of press brakes features stronger structures and frames compared to the lighter models, due to the increased force of the hydraulic cylinders. Additionally, the sheet metal used in their construction is thicker than that of the light models.
3- Heavy Press Brakes by Baghirian Machine Manufacturing
Press brakes with a tonnage exceeding 250 tons manufactured by Baghirian Machine Manufacturing are classified as heavy press brakes. The power (tonnage) and weight of these press brakes are higher than those of the other models, and some models in this category require a foundation (for the 6-meter models). Due to the high weight of these press brakes, loading and transportation require more attention and care. These models are used in workshops for manufacturing steel structures, heavy industries, and the production of metal equipment with strong frameworks. They are primarily designed for bending sheets longer than 3 meters and thicker than 10 millimeters. Notably, the 4-meter and 6-meter models in this category can be tandemized. In other words, two mirror-image machines are manufactured and placed side by side to create 8-meter and 12-meter models.
| Model | Power (Ton) | Maximum Bending Length | Approximate Weight | Ram Stroke |
| HB 3035 | 350 | 3050 mm | 20 ton | 350 mm |
| HB3040 | 400 | 3050 mm | 23 ton | 350 mm |
| HB4030 | 300 | 4050 mm | 23 ton | 300 mm |
| HB4040 | 400 | 4000 mm | 25 ton | 300 mm |
| HB6025 | 250 | 6100 mm | 24 ton | 250 mm |
| HB 6030 | 300 | 6100 mm | 27 ton | 300 mm |
| HB6040 | 400 | 6100 mm | 36 ton | 350 mm |
| HB6060 | 600 | 6100 mm | 47 ton | 350 mm |
| HB6080 | 800 | 6100 mm | 60 ton | 400 mm |
