In the competitive world of industrial production, one of the most important concerns of factory managers is reducing production costs without quality loss. As the heart of many production lines, impact presses play a direct role in productivity, output and final cost of goods. But with the increase in the price of new industrial machinery, many factories have gone to buy or refurbish second-hand presses. In the meantime, the prestigious collection Rezaei brothers in Tehran with expertise in overhauling and sale of second-hand impact presses is considered a reliable option for the manufacturing industries of the country.
What is impact press overhaul?
Overhaul means complete reconstruction of an industrial device; so that its performance is similar to a new device. In the overhaul process of the impact press, all worn parts, power transmission systems and control parts are checked and replaced to restore the original accuracy and power of the device.
The main overhaul steps of the impact press include the following:
- Complete disassembly of main parts (flywheel, crankshaft, mandrel and bushings)
- Complete washing and descaling of metal parts
- Replacement of damaged bearings and shafts
- Inspection of clutch and brake system
- Reset of impact course
- Painting and final test according to production line conditions
Baradran Rezaei factory offers every second-hand impact press machine after technical overhaul and final control along with warranty and installation services.
Why is overhaul more economical than buying a new device?
More than 70% of the cost of factories is spent on production equipment. Buying a new impact press may be several times the production budget. While the overhaul of second-hand presses reduces the cost by 60% and has the same performance as a new machine.
Another advantage of the overhaul is the fast supply of the device. The production of a new press may take months, but the overhauled presses of Tehran's Rezaei Brothers factory are ready to be delivered in the shortest possible time.
Advantages of blow press overhaul to reduce production cost
1. Economic efficiency in initial investment
Purchasing an overhauled impact press frees up your capital for other parts of the production line; While the efficiency of the machine is almost the same as the new press.
2. Reducing the cost of repairs and stopping the production line
In a complete overhaul, worn and dangerous parts are replaced. This prevents sudden breakdowns and minimizes production stoppages.
3. Increasing the useful life of the device
The impact press gets a new life after restoration. With lubrication and basic service, its performance remains stable for years.
4. Improve operator safety
Overhaul includes updating brake and clutch systems that prevent work accidents. Baradaran Rezaei factory installs a new safety system in all the refurbished machines.
5. Coordination with actual production needs
Overhauled impact press is adjustable according to production capacity and factory space. The possibility of changing the dimensions of the table, adjusting the course and speed is one of its important advantages.
Overhaul technical steps in Baradaran Rezaei factory
Detailed inspection and troubleshooting
Baradaran Rezaei engineering team first checks the device with accurate measuring equipment to determine technical problems and wear and tear.
Restoration of mechanical parts
Wearable parts such as cranks, bushings, pins and pins are replaced or re-machined. In this section, resistant alloy steel is used.
Repair or replacement of electrical and control system
In some old presses, the electrical system is old and dangerous. This part will be replaced with a new control panel and a safe emergency switch.
Industrial painting and performance testing
All devices are industrially painted after final assembly and undergo several impact, temperature and pressure tests to ensure final quality.
The difference between refurbished and overhauled second-hand presses
A second-hand press without an overhaul usually only looks healthy, but the internal parts are worn. On the other hand, Baradaran Rezaei's overhauled press works like a new machine after complete restoration and precise adjustment.
Comparison factor of ordinary second-hand press, rehabilitated Baradaran Rezaei press, lifespan 2 to 3 years, more than 10 years, low safety, very high accuracy, variable performance, stable and precise, high maintenance cost, very low, no after-sales service, full warranty and support
Overhauled presses; Special choice for small and medium industries
The overhauled impact press is a smart choice, especially for workshops and small factories. These collections often look for devices that:
- Have low initial cost
- Have easy maintenance and parts available
- Get real after sales service
All these features are present in the overhauled devices of Rezaei brothers.
Specialized overhaul services in Tehran
Baradran Rezaei factory in Tehran operates as one of the specialized centers in the repair and sale of impact presses and provides the following services:
- Complete reconstruction of body and power transmission system
- Replacement of industrial oils suitable for each model
- Installation of new protection system
- Technical test with standard templates
- Operator training after delivery of the device
Successful experience of factories with overhauled devices of Rezaei brothers
Dozens of factories in the automotive, home appliance, and component manufacturing industries use Rezai Brothers' refurbished presses. Reports have shown that these devices have solved up to 90% of sudden failure problems and their useful life has increased from 5 to more than 12 years.
Energy cost reduction with a reengineered impact press
One of the important points in industrial production is electricity consumption. Old impact presses have high energy consumption. But in the overhaul process, Baradaran Rezaei installs low-consumption three-phase motors and an automatic lubrication system to reduce electricity consumption by 30%.
As a result, the factory with the same production will have much lower electricity consumption and energy costs.
The importance of choosing a reliable center for overhaul
Overhaul of impact press is a technical and precise work, and if it is done in non-specialist workshops, it may be dangerous. Baradran Rezaei in Tehran, with experienced engineers, subjects the refurbished devices to technical tests, vibrometry and impact testing to ensure 100% safety.
Important points when buying an overhauled press
- Check the technical test certificate and health of the device
- Ensure warranty and after-sales service
- View overhaul documents including the list of replaced parts
- Test the device before purchase
- Choose a reputable brand such as Baradaran Rezaei
Used or overhauled impact press; Which is more economical?
If the plant is just looking for a quick start at low cost, a simple used press is a temporary option. But if you are looking for long-term stability, safety and high precision, the overhauled press is the best choice.
The difference in the initial cost is negligible, but the operating profit will be many times over in the long run.
conclusion
Overhaul of second-hand presses is one of the most economical methods to reduce production costs and increase productivity in metal industries. With technical and detailed restoration, a device that may have been unused for years returns to the production cycle.
The Rezaee brothers group in Tehran, with a long history in the sale and overhaul of impact press machines, is the main reference of the country's industries in this field. The quality of construction, real support and the provision of a valid warranty have made various industries benefit from the refurbished presses of this factory.
