What tasks can be easily solved by the EP Series CNC Electric Screw Press?
2026-07-01
Modern forging requires equipment that combines precision, energy efficiency and versatility.EP Series CNC Electric Screw Press- this is exactly such a tool. Featuring direct drive from a brushless motor and programmable force control, this press handles hot stamping, sizing, blanking and even coining operations with ease. Our specialists have successfully implemented solutions based onEP Series CNC Electric Screw Pressat automotive industry enterprises in the Kaluga region and in the defense sector, where the requirements for repeatability and stability are especially high.
The versatility of the technology: what problems does the press solve?
CompanyQingdao Hongdao Metalworking Equipment Companydesigns and produces this equipment taking into account the specifics of the Russian market.EP Series CNC Electric Screw Presseasily copes with three main groups of tasks.
The first task is hot stamping of complex forgings, including parts made of special steels and titanium alloys. Thanks to the high rigidity of the bed and the precise positioning of the ram, the press ensures minimum tolerances even when working with high-temperature workpieces. The second task is calibration and straightening of finished parts after heat treatment, where it is important to apply strictly measured force without overload. The third task is cutting and trimming the flash from the forgings, which eliminates additional operations on the shear press. Our clients from Yekaterinburg noted that with the advent of this press, the production cycle was reduced by 20%.
Technical Parameters of EP Series
Below are the key characteristics of the model range that are most in demand in mechanical engineering and metalworking. The data is based on specifications that we adapt to the requirements of Russian GOST standards.

| Mass (kg) | 24000 | 45000 | 75000 | 120000 |
In every modelEP Series CNC Electric Screw Pressan integrated force control system with motor current feedback provides an error of no more than 1% of the set value. This allows the press to be used for precision operations where it is important to maintain the geometry of the part.
Advantages for Russian production
We are inQingdao Hongdao Metalworking Equipment CompanyWe understand that two factors are critical for Russian factories: reliability and ease of maintenance. The design of the press does not contain hydraulic components, which eliminates oil leaks and does not require constant replacement of filters - relevant for the conditions of Siberia and the Far East. The absence of a hydraulic system also allows the operationEP Series CNC Electric Screw Pressat temperatures down to –25°C in unheated workshops, which is confirmed by the experience of our customers in Irkutsk. In addition, the CNC system with a Russian-language interface allows you to quickly change equipment to different types of dies, reducing downtime.
Frequently Asked Questions: What problems does the EP Series CNC Electric Screw Press solve?
Question 1: How to choose a press model for hot stamping of parts made of 30KhGSA steel with a force of up to 800 tons?
Answer: For a force of 800 tons (about 8000 kN), the optimal model is EP-1000 (nominal force 10000 kN). When choosing, it is also important to take into account the impact energy - for parts of complex shapes with a large amount of deformation, an energy reserve of at least 20% is needed. Our engineers perform calculations based on the forging drawing, determining the required deformation work. For steels of type 30KhGSA, we also recommend taking into account the die filling factor - we advise each client in detail on this issue to avoid overloading the equipment.
Question 2: Do I need a special foundation to install an EP series press in an existing workshop?
Answer: Yes, for presses with a force of 4000 kN or more, a separate foundation with a depth of at least 1.2 meters with vibration isolation is required. Our specialists provide foundation drawings indicating the loads on the soil. For the EP-400 model, the press weight is 24 tons, the foundation must be designed for a static load of at least 40 tons, taking into account dynamic vibrations. We also offer a supervising installation service, in which an engineer supervises the pouring of the foundation and the leveling of the frame.
Question 3: What is the maintenance schedule and what parts are subject to scheduled replacement?
Answer: For EP series presses, the main focus is on lubrication of the guides and main shaft bearings - the interval is 500 hours of operation. Once every 2000 hours, the force sensor needs to be calibrated and the condition of the brake system checked. Unlike hydraulic presses, there are no filters or seals that require frequent replacement. The main consumables are lubricants and safety couplings. We keep a stock of belts and electronic boards in a warehouse in Moscow, which ensures prompt delivery if necessary.
Time-proven reliability
Over the years of work in the Russian marketQingdao Hongdao Metalworking Equipment Companydelivered more than 50 unitsEP Series CNC Electric Screw Press. The equipment has EAEU certificates of conformity and can be integrated into automated process design systems. An illustrative example is the introduction of three EP-1000 presses at a plant for the production of railway wheelsets in the Sverdlovsk region, where the equipment has been operating since 2019 without major overhaul.
