How the EP Series Electric CNC Screw Press Shapes the Future of Metalworking
2026-07-14
The industrial manufacturing landscape is undergoing a precision revolution, and at its center isEP Series CNC Electric Screw Press. This detailed guide explains why this advanced forging equipment is rapidly replacing traditional friction presses in the aerospace, automotive and heavy-duty industries. We look at its key benefits, from unrivaled energy accuracy and eccentric load tolerance to a reliable, low-maintenance design. Based on technical parameters and real application examples, the article demonstrates that the EP series produced by industry leaders such asHONGDUAN, is not just a machine, but a strategic investment in sustainable and high-performance production.
1. Introduction: a paradigm shift in forging
The industrial forging sector is undergoing a decisive shift. For decades, mechanical and hydraulic presses, especially friction screw presses, have been the primary equipment for metal forming. However, demands for higher precision, energy efficiency and automated control have paved the way for a new generation of equipment. Enters the stageelectric cnc screw pressis a machine that redefines the possibilities of hot stamping, precision forging and embossing.
The EP series, as described on HONGDUAN's official product page, represents the culmination of this technological evolution. These machines are designed to meet the stringent demands of modern production lines, offering a combination of high precision, adaptability and environmental friendliness. Unlike traditional presses, which consume energy continuously, electric screw presses consume energy only during the power stroke, delivering energy savings of over 48% compared to equivalent friction presses. This makes the EP Series a cornerstone for manufacturers looking to reduce operating costs and reduce their carbon footprint.
2. Why the EP series? Key Advantages of CNC Electric Screw Presses
The EP Series stands out thanks to a set of powerful features that directly impact product quality and production efficiency. Based on technical documentation and industry analysis, key benefits include:
Unsurpassedprecision and control
At the heart of the EP series is a high-torque servo drive (often using a switched reluctance motor) that provides precise, programmable control of forging energy and impact force. This results in exceptional product stability, reduced material waste and superior surface quality. The absence of a fixed bottom dead center eliminates the risk of jamming or overloading, protecting the die and the machine itself.
High resistance toeccentric loads
One of the outstanding engineering achievements of the EP Series is its superior resistance to eccentric loads. This is achieved by a dual guide system (round guide and X-shaped guide) which provides long guide length and high rigidity. This design is critical for multi-strand forging, where uneven forces often occur, ensuring that the ram remains aligned and the forging process is stable.
Energy efficientstrength and stability
In an era of rising energy prices, the EP Series provides a significant advantage. The direct or gear drive operates with high efficiency and the start-stop mode minimizes idle energy consumption. This not only reduces energy costs, but also creates a quieter, cleaner work environment.
Ease of maintenance andreliability
The mechanical design of the EP series is significantly simpler than that of hydraulic systems. Fewer components and a patented screw and nut lubrication system reduce wear and tear significantly. This means less frequent maintenance, longer service life and higher overall equipment efficiency (OEE).
3. Specifications: main parameters of the EP series

7. Frequently asked questions (FAQ) about EP series presses
Question 1: What is the fundamental difference between the EP series electric screw press and the traditional friction press?
Answer: Electric screw press uses direct or gear servo drive, which provides precise energy control, high efficiency and reduced maintenance requirements. Traditional friction presses operate by disc friction and have lower efficiency and less accuracy. Additionally, the EP series does not have a fixed bottom dead center, eliminating overdrive.
Question 2: Can EP series withstand eccentric loads in multi-strand forging?
Answer: Yes. One of the key advantages is the high resistance to eccentric loads due to the design with long double guides (e.g. round and X-shaped). This makes it ideal for complex forging operations.
Question 3: What industries typically use EP series presses?
Answer: EP series is widely used in aerospace, automobile, railway, power (wind, nuclear), heavy machinery and even kitchenware industries.
Question 4: Is the EP series energy efficient?
Answer: Absolutely. It is designed for high efficiency, consuming energy only during the power stroke. This saves more than 48% energy compared to traditional friction presses.
Question 5: What type of motor does the EP series use?
Answer: Switched reluctance motor (SRM) or brushless direct current (BLDC) motor is usually used. These motors have high starting torque, excellent speed control and high reliability.
