Servo Direct Drive Electric Screw Press (J58ZKA 250-10000T)

Servo Direct Drive Electric Screw Press (J58ZKA 250-10000T)

The J58ZKA Series Servo Direct Drive Electric Screw Press is designed for precision hot forging, closed-die forging, coining, sizing and other metal forming applications. Its permanent-magnet synchronous servo motor directly drives the screw system, providing precise forging energy control, high transmission efficiency and consistent forming accuracy.

✅ Servo Direct Drive

The permanent-magnet synchronous servo motor directly drives the screw system, shortening the transmission chain and improving transmission efficiency.

✅ Precise Forging Energy Control

Servo control enables accurate adjustment of forging energy for stable, repeatable forming and consistent forged-part quality.

✅ High-Rigidity Frame

The rigid machine structure provides high stability during forging and strong resistance to eccentric loads, helping improve forming accuracy and die service life.

✅ 250–10000T Model Range

The J58ZKA Series is available in multiple press capacities for different forged components, die sizes, production requirements and automation configurations.

Product Features

Servo Direct Drive Electric Screw Press
J58ZKa series Servo Direct Drive Electric Screw Press is a screw press in which the motor rotor is directly connected to the screw rod to change the rotation direction of the flywheel. Frame has higher rigidity, more precise control of blow energy, and higher forging efficiency. Suitable for various precision forging, coining, precision pressing, stamping, calibration and other processes.
Features
Higher energy output accuracy/increase forging accuracy and die life Synchronous motor direct drive/higher transmission efficiency Various frame types/suitable for automatic forging High overall rigidity and strength/higher stability No transmission wearing parts and energy loss/low energy consumption Flywheel adopts friction overload protection/safe and reliable Advanced intelligent control system/remote maintenance, online detection, OEE data, maintenance reminders Optional/intelligent modules, quick mold change, mold spray lubrication, flue gas treatment and other automated peripheral equipment
High Efficiency
Utilizes an AC permanent magnet synchronous servo direct-drive motor, with shorter excitation time increasing the striking frequency by over 10%.
Zero Transmission, Low Energy Consumption
The servo direct-drive motor transmits torque directly to the screw, improving transmission efficiency by over 20% and saving 8%-10% more energy compared to standard asynchronous motors.
High Reliability
Featuring a simple and rational structure with a short drive chain, it incorporates flywheel friction overload protection and a lubricated transmission system. This design ensures minimal mechanical failures, easy maintenance, and extended equipment service life.
High Precision
Utilizing servo control technology, it enables precise control of striking energy with excellent stability. The integrally cast steel body ensures superior overall rigidity, while the X-type long guide rails provide strong resistance to eccentric loads. This results in high forming accuracy and outstanding consistency of the product.
