Hydraulic presses that are produced as a type in this company are divided into two groups: c-shaped (in capacities of 63 and 100 tons) and gate (in capacities of 160 tons and above). The application of these presses is often the deep shaping and stretching of parts made of sheet metal, especially in the automotive and home appliance industries.
Due to the flexibility of hydraulic systems in controlling parameters such as force, position, speed and time, various types of hydraulic presses with different and specific uses are also custom designed and produced in this company.

The body of the presses produced by this company are generally made of steel sheet parts that are welded together. After welding, tensioning operation is performed. After that, the living surfaces of the fixed and moving parts of the machine are carefully machined by the boring machine. Doing the above causes the parallel accuracy of the table and slide surfaces of the machine and the orthogonality of the slide to the table surface is maintained over the years, and finally, in addition to producing high quality parts, the life of the press and mold is maximized. Although in C presses, the shape of the press body is reinforced at the necessary points so that the opening of the opening in the permissible range is in accordance with international standards, but the minimum opening of the opening also causes problems in making some precise parts. For this reason, the body of these presses is secured from the front with two steel arms. When the low opening does not cause problems, these two arms can be separated from the press to provide easier access to the space between the table and the slide. In large gate presses, the body is made in several pieces and the body components are connected to each other by several steel rods (Tie Rod) and related nuts. When assembling the body parts, these rods are pulled by a special hydraulic tool with hundreds of tons of force and are fastened in place when the end nuts are stretched.

Hydraulic power pack:

Hydraulic parts made by the most reputable manufacturers

The various parts used in the hydraulic power pack are selected from the most well-known global brands. These parts include pumps, valves, filters, pressure monitors and the like. In addition to the high quality of the part, the presence of a reputable representative in the country to provide after-sales service and easy supply of spare parts is also an important criterion that is considered in selecting the manufacturer of these parts.
Use the manifold

By using the manifold in the hydraulic circuit, piping and the use of connections are minimized and leakage of the hydraulic circuit is easily done. Other advantages of using a manifold include saving space and easy access to parts during repairs.
Use NPT connections

The use of high pressure fittings in which the threads are conical (incomplete cone) and also sealing the threads with special varnishes resistant to pressure and heat ensures no oil leakage from these fittings.

Use of anti-vibration and rubber fittings

In hydraulic power pack, using suitable types of anti-vibration and rubber fittings such as high pressure hoses, the parts that cause shock and vibration are completely isolated to prevent damage to other parts.

 Oil filtration

Maintaining oil quality is very important in a hydraulic system. Due to this, suitable types of filters are installed in the path of oil movement. In large presses, the filtration circuit is independent of the main hydraulic circuit and has a separate motor pump. The use of filters that signal their contamination to the control system with an electrical signal also makes troubleshooting and service easier.


Independent pilot circuit

In large presses, the pilot circuit (hydraulic steering) is independent of the main circuit and has a separate pump motor, which increases the safety of the hydraulic system.

Oil temperature control

High oil temperatures quickly damage a hydraulic system. Therefore, cooling the oil that is heated by friction in the hydraulic circuit and maintaining its temperature in the appropriate range is very important. Depending on the different conditions, converters that reduce the oil temperature by air or water, along with other necessary control elements, are installed on the press so that the oil temperature is always in the desired range.

 hydrulic jacks :

Honing cylinders

To make hydraulic cylinders, honing steel pipes made by reputable European manufacturers are used. Non-oil leakage, even to a small extent and longer durability of the sealing parts inside the cylinder, is one of the advantages of using honing pipes.

Hardened piston rod

The surface of the piston steel rod is hardened to a few millimeters by penetration, then it is completely polished by the stone-axis machine. This process ensures the durability of the piston over the years of operation.

Advanced sealing system

The design of the structure of hydraulic jacks is based on the most evolved patterns in the world today. A set of different parts together form a sealing system. These parts are heat, pressure and abrasion resistant depending on the type of part and installation place and are selected from the most prestigious global brands.

Slides and cushions :


To maintain the alignment of the surfaces of the slide and cushion plates with the press table and to maintain the orthogonality of the movement path of these plates, the slide and cushion have long and precise guides covered with bronze phosphor alloy. In addition, the necessary grooves for storing grease are installed on the mentioned coating.

 Determine and control the position of slides and cushions

Determining and controlling the position of slides and cushions, depending on the use and model of the press, is done by microswitches or sensors or suitable types of precision instruments (rulers or encoders).

 Free Fall

Typically, slide presses used for traction have at least three different speeds in a cycle, including slide down (no load), under load, and return speed. In large presses with a long stroke, elements are added to the hydraulic circuit so that the slide can travel part of the stroke at high speed under the influence of its own weight. Using this system, called free fall, saves time and energy.

Hydraulic Shock Absorber

This system is used when we want to use hydraulic press for cutting molds. In the cutting process, when the piece (Blank) is detached from the sheet, a shock enters the hydraulic circuit, which damages the different parts over time. This system consists of two or more jacks and other hydraulic elements that have a function similar to a shock absorber in a car. The impact created by this device is absorbed and damage to the hydraulic system is prevented.
Slide Locking
For safety, when installing the mold or press service, it is necessary to make sure that the slide does not move downwards under any circumstances. For this purpose, one or more spacers are usually used, which are placed between the slide plates and the press table. Sometimes all the space between the slide and the table is occupied by the mold and there is no space to place these spacers. To solve this problem, a device called Slide Locking is installed around the slide press. When necessary, the steel tabs of this device are inserted by horizontal hydraulic jacks into the holes that are installed in the sides of the slide and prevent the vertical movement of the slide in any situation.

Control system

PLC is used in all control panels. Depending on the application and the type of press, there are different types of precision instruments (electronic rulers, encoders, pressure and temperature and current transmitters, etc.) in the control system. LCD screens, mime panels and touch screens are also used to communicate with the operator. With the aim of easy access of the buyer to the spare parts and less dependence on the press manufacturer, the PLC used is one of the most reputable and well-known global brands (SIEMENS). Also, other electrical parts are selected from the highest quality brands that have a reputable representative and after-sales service in Iran.

Setup and training, 12-month warranty and ten-year after-sales service

After transporting the device and announcing the readiness of the buyer, the technician of this company will be sent to the buyer's factory to set up and teach how to operate and maintain the device. If the mold is ready and the buyer wishes, the installation and initial settings of the mold are done by the East Press technician, after producing a number of test pieces, the press is delivered to the buyer while working. All the above cases are done with the guarantee of all mechanical parts of the device for one year after commissioning without receiving any cost. Also, the company is committed to providing after-sales service (supply of parts and dispatch of service) for at least 10 years for a fee.
