In today's highly competitive industrial world, production line machines and equipment play the role of the beating heart of factories. Among these equipments, impact press machines are of special importance due to their wide application in parts manufacturing, automobile manufacturing and household appliances industries. But with the passage of time and continuous operation, these devices suffer depreciation and require major repairs. Repairing and refurbishing used presses is not only a smart economic solution, but it can bring production efficiency to the level of new machines. In this article, we are going to examine the process of overhaul and renovation of presses and explain the role of the Rezai brothers' impact press specialist group in providing high-speed services and guaranteeing quality.
Why repairing and renovating used presses is the best option?
Purchasing a new press, especially in the current economic conditions and currency fluctuations, imposes a very heavy cost on producers. On the other hand, many old presses have very strong bodies and chassis and high-quality alloys that are less common in newer models. Therefore, repair and reconstruction of used presses is considered a strategic option.
By entrusting your device to specialists like Baradaran Rezaei Brothers Impact Press, you will own a device that meets the world's standards in terms of performance, accuracy and safety, by spending much less money than buying a new device. Correct restoration can increase the useful life of the device by several years and prevent sudden stops of the production line that cause irreparable damages.
The specialized steps of repairing and renovating the press in the Rezaei brothers complex
The process of repairing and renovating used presses is not an easy task and requires deep technical knowledge, long experience and advanced equipment. In Rezaei Brothers Impact Press, this process is carried out through precise and engineered steps to ensure that the final machine is delivered to the customer with the best quality.
1. Early and accurate troubleshooting
The first step in repairs is to correctly diagnose the fault. First, our experts prepare a complete list of the device's faults by carefully checking the device's performance, unusual sounds, vibrations, and the quality of the output parts. This step is very critical because ignoring a small defect can lead to big failures in the future.
2. Complete disassembly of the device (Disassembly)
To perform a major rebuild, the device must be completely disassembled. All moving and fixed parts are separated and washed. This allows for small cracks, corrosion and hidden wear to be revealed in parts such as crankshafts, connecting rods and gears. Baradaran Rezaei impact press uses special tools to perform disassembly without damaging sensitive parts.
3. Checking and repairing the crankshaft and bearings
The crankshaft, as the main moving part of the press, is under heavy pressure. In the process of repair and restoration of used presses, the health of the crankshaft is checked in terms of warping and wear. If necessary, accurate grinding or replacement of the crankshaft is performed. Also, the bronze bearings and bushings that are loose are replaced with the best material so that the accuracy of the striker's movement returns to the standard state.
4. Table and slide modification and machining
One of the most important factors in the quality of the production piece is the parallelism of the table and movable jaw. Over time, the surface of the table may become damaged or uneven. The technical team Baradaran Rezaei's impact press using precision turning and milling machines completely correct the surfaces and create exact parallelism. This work increases the lifespan of molds and reduces production waste.
The importance of high speed in the repair process
One of the main concerns of factory managers is the downtime of the production line. Every day that the press is off, a significant financial loss is brought to the collection. For this reason, repairing and renovating used presses at high speed is one of the main competitive advantages of Baradaran Rezaei impact presses.
We minimize machine downtime by having multiple work teams and a stock of spare parts. Careful planning of the renovation project ensures that there are no delays in the supply of parts or machining processes. High speed, along with accuracy, is our constant motto so that your production wheel will be running again in the shortest possible time.
quality assurance; Our commitment to customers
High speed should not sacrifice quality. In the industrial repair market, many unauthorized repairmen use low-quality parts and unprincipled methods to start the device temporarily, which breaks down again after a short period of time. But in Rezaei brothers' impact press, quality assurance is an inviolable principle.
We guarantee all services provided in the field of repair and restoration of used presses. The use of standard alloys in the manufacture of bushings, the use of electrical and pneumatic equipment of reputable brands and the completion of rigorous final tests are part of our quality assurance process. After the final assembly, the device is tested under rated load to ensure the proper functioning of the clutch, brake and lubrication system.
Improvement of safety and control systems (Retrofitting)
Refurbishment does not only mean repairing failures, but also an opportunity to upgrade the technology of the device. Old presses usually lack modern safety systems and smart electrical panels. During the repair and restoration of used presses, the specialists of Baradaran Rezaei impact presses offer special suggestions for the modernization of the machine:
- Installation of PLC and HMI systems: Replacement of old control circuits and contactors with intelligent PLC systems that allow for more accurate programming and easier troubleshooting.
- Installation of light and safety curtains: In order to save the life of the operator and comply with the requirements of work management, it is very necessary to install optical sensors and safe two-thumb systems.
- Upgrading the lubrication system: Changing oil systems Manual or old work to central automatic systems with the ability to warn in case of oil pressure drop, which guarantees the life of the device.
- Installation of overload systems: To prevent excessive pressure on the device and break the mold or crankshaft, it is recommended to install hydraulic overload systems.
The role of clutch and brake system in press performance
One of the most depreciating parts of impact presses is the clutch and brake assembly. The poor performance of this system causes the machine to not stop at top dead center or to slip during impact, which is very dangerous. In the process of repairing and renovating used presses, the Baradaran Rezaei impact press series pays special attention to this part.
Converting old mechanical clutches to new pneumatic (air) clutches and brakes is one of our specialized services. Pneumatic clutches have higher operating speed, more safety and less noise, and their control is done by safe solenoid valves. The reconstruction of pads, disks and felt bowls of this system is done with micron accuracy to achieve the best performance.

Common problems with impact presses that require rebuilding
Knowing the signs of failure will help you to repair and rebuild used presses before major accidents occur. Some of these problems are:
- Abnormal noise from the ribs: indicates loose or broken ribs or bearing failure.
- Hot bearings and bushings: usually happens due to lack of oil or too tight bushings and needs to be checked immediately.
- Polishing of production parts: This problem is directly related to the misalignment of the table and the jaw or the slackness of the crankshaft, and it can be solved by careful rebuilding.
- Oil and wind leakage: In addition to dirtying the working environment, continuous leaks cause pressure drop and defective operation of the machine.
Technical team of Baradaran Rezaei Press finds the root of the problem and solves it fundamentally by knowing these symptoms. We don't just replace the defective part, we identify the cause of the failure to prevent it from happening again.
The importance of lubrication and preventive maintenance after rebuilding
After repairing and rebuilding used presses, how to maintain the machine plays an important role in its lifetime. One of our services is training operators and technical personnel of your plant for proper maintenance. The lubrication system should be checked daily. It is vital to use oils with the right viscosity recommended by Baradaran Rezaei Impact Press.
Also, compiling a regular net program (maintenance and repairs) makes the device always in peak readiness. We advise our customers not to forget periodic inspections even after a complete restoration. Our experts are ready to periodically visit your devices in the form of service and maintenance contracts.
Converting manual presses to automatic
Many older presses still use a manual feeder, which slows down production and poses a risk of amputation for the operator. During repair and reconstruction of used presses, we can equip your machine with all kinds of automatic feeders (roll feeder, servo feeder). This multiplies the speed of production and reduces the need for manpower. Baradaran Rezaei impact press has a high expertise in synchronizing the press with automatic feeders.
