Servo Press FAQ's

Q: How does the programmable slide motion improve stamping quality?

A: Unlike conventional presses with a fixed mechanical cycle, SEYI Machinery servo presses offer 7 default motion profiles and 1 free motion. You can slow the slide down during the forming process for better material flow and speed it up upon return, which eliminates spring-back and cracks in high-strength materials while reducing tool wear.

Q: What are the best use cases for SEYI servo presses?

A: The flexibility of the servo series makes them ideal for a wide variety of applications. Common uses include complex progressive die stamping, deep drawing, and hot stamping lines. They are particularly effective for manufacturing high-precision parts in the automotive (including EV relay bases), aerospace, medical, and 3C (computer, communication, consumer) electronics industries.

Q: Can a servo press help me save on electricity and power?

A: Yes. By replacing traditional mechanical components with a high torque-low RPM servo motor, you only consume power when the press is actually working. Additionally, built-in power stabilization and regeneration systems capture and store mechanical energy in capacitors, which eliminates power surges and conserves electricity.

Q: How do SEYI servo presses handle difficult-to-form materials?

A: Using features like Hold motion (which pauses the slide at the bottom of the stroke) and Vibration motion (which facilitates material flow), the presses are expertly suited for advanced, high-tensile materials. You can even form highly complex, thin-walled parts in a single stage that would normally require multiple stages on a traditional press.

Q: What safety and machine protection features are included?

A: All machines are equipped with electronic overload protection, which responds immediately to prevent damage to the die and the press. Additionally, the heavy-duty ribbed frame structure is designed to absorb vibrations from pendulum motion, and the 8-point gib slide guiding helps maintain precise alignment.
