Choosing the right impact press machine is one of the most important decisions in any manufacturing plant. This device plays a key role in the speed, quality and economy of production lines. In today's market, the high variety of impact presses has made it difficult for technical and industrial managers to make decisions. Rezaee Brothers brand in Tehran, with years of experience in the production and sale of industrial impact presses, is a reliable reference for many Iranian factories. In the following, we have done a complete technical and economic review on how to choose a suitable impact press.
What is impact press and what is its use?
The impact press machine is one of the most widely used machines in metalworking and component production lines. Its operation mechanism is designed based on the mechanical impact of the crank and crankshaft, which applies a large compression force to the part. This force changes the shape, cuts or forms the metal sheet.
Common applications of the impact press are in the following industries:
- Production of automobile parts
- Manufacturing of metal household appliances
- Packaging and canning industries
- Manufacturing of electronic metal parts
- Manufacturing of structural parts and industrial connections
Why is it important to choose the right impact press?
Choosing the right device is not only dependent on price or brand. Several factors affect performance, durability, and operating costs. A wrong choice can lead to premature depreciation, high power consumption, reduced forming accuracy or even stopping the production line.
The reasons for the importance of choosing the right impact press:
- Increasing production accuracy and reducing material waste
- Reducing energy consumption
- Longer device life
- Optimizing production speed
- Compatibility with existing molds and peripheral devices
Getting to know the types of impact presses
In the Iranian market, especially in Tehran, there is a wide variety of impact presses. Knowing its types helps to make a more accurate choice.
Mechanical impact press
The mechanical press is the most common type that transmits power using a flywheel and a crank. Suitable for high circulation productions and standard formats.
Advantages:
- High speed
- Low need for service and maintenance
- Adjustable impact course
Rezai Brothers is one of the best domestic producers of this type of presses.
Hydraulic impact press
In this type of press, power is transmitted through hydraulic fluid. It is a better option for precise shaping and thicker parts.
Advantages:
- Precise force control
- Adjustable movement speed
- Suitable for special parts and low-run production
Pneumatic impact press
Another type that works with compressed air and is mainly used in light assembly lines.
Advantages:
- High performance speed
- Low maintenance cost
- Suitable for semi-automatic production
Important technical factors in buying an impact press machine
When buying an impact press, you should carefully check several technical features:
Nominal power of the machine (tonnage)
The power of the press is expressed in tons. Choosing the right tonnage depends on the thickness and type of material. For example, in the production of 2 mm steel sheet, a press of 30 to 40 tons is enough. But in forming thicker parts, you need machines of more than 100 tons.
Diameter and stroke
The longer the stroke, the greater the range of motion of the mandrel, which is useful for deep operations. On the other hand, for fast and shallow cuts, a shorter stroke is better.
stroke rate per minute (SPM)
The amount of SPM indicates the production capacity. Devices with higher speed are suitable for mass production.
Baradran Rezaei factory offers different models of impact press with global standard SPM.
Clutch and brake type
The safety and control of the press is largely dependent on the clutch and brake system. New presses use electromagnetic systems that have a faster response.
The depth of the throat and the distance from the table to the mandrel
These variables specify the dimensions of the part that can be placed in the device. Before buying, it should be checked according to the dimensions of the molds and parts of the production line.
The difference between Iranian and foreign impact presses
Foreign presses from Japanese or German brands usually have higher prices and higher maintenance costs. On the other hand, domestic production devices such as Baradran Rezaei products with high technical standard and domestically available parts are a more logical choice for Iranian industries.
Features of Baradaran Rezaei impact press machine:
- Production according to CE and ISO9001 standards
- Ductile cast iron body with high vibration resistance
- Use of hardened steel shaft
- Central lubrication system
- Ability to install automation and sheet feeder
Tips to increase the life of the impact press machine
- Regular lubrication of all moving parts
- Precise adjustment of course and pressure according to the mold
- Using a trained operator
- Sending the machine for annual service to the Rezai brothers collection
- Using standard oil and healthy cooling system
Selection of the impact press based on the type of production
Mass production of duplicate parts
In this case, the mechanical press has a higher speed and a lower price.
Suggestion: high-speed models of 30 to 50 tons of Rezaei brothers.
Production of special parts with complex form
Hydraulic or pneumatic press provides better control.
Suggestion: Digital control models of 60 tons and above Baradaran Rezaei factory.
Semi-industrial and small workshops
Desktop or portable impact presses are more economical.
Suggestion: Small series of 15 to 25 tons with low electricity consumption.
Advantages of buying directly from Baradaran Rezaei factory in Tehran
- Non-intermediate purchase at competitive price
- Real warranty and after-sales service
- Free commissioning and operator training
- Genuine and available spare parts
- Telephone and face-to-face support for specialized settings
Baradran Rezaei, with a 30-year history in the production of industrial machinery, is one of the most reliable suppliers of impact presses in Tehran. Various factories, from automobile industries to household appliances, are fully satisfied with the quality and durability of the devices of this collection.
New or second-hand impact press; Which option is better?
Although new machines have certain technical advantages, sometimes it is more economical to buy a second-hand press from reliable sources. Important points in checking second-hand impact presses:
- Health of table and shaft
- Real pressure with test gauge
- Uniform sound of engine and flywheel
- No cracks in the body
Baradran Rezaei factory, in addition to selling new machines, offers refurbished presses with warranty, which is an excellent economic option for newly established workshops.
Side costs of buying an impact press
Before buying, you should pay attention to the side costs:
- Installation and commissioning
- Three-phase power system and control panel
- Sheet feeder and decoiler
- Periodic maintenance and inspection
- Operator training
