SDE series offer flexible stamping profiles to operate various processes for medium & large auto lightweight parts, especially suitable for drawn parts thanks to eccentric gear design. Its Hold Motion can fulfill hot stamping process for high-strength steel and aluminum. Below are the main features:

• High rigidity and 3-piece tie-rod design to increase the durability.
• From 400 ton to 2400 ton SDE servo press provided for different requirements.
• In-house designed servo motor for presses with low revolution speed and high torque to actualize Hold Motion for hot stamping process.
• Optimized slide motions to decrease vibration, noise and heat, extending the tool life and enhancing productivity.
• Patented power management system to save more than 30% of power consumption.
• Pendulum Motion to cope with progressive dies can double the production rate at most.
• Highly integrated with peripherals, robots and transfers for press lines.
• Friendly user interface for easy setups and automated die change with one-button start to save time and increase safety.
• Smart machinery: to support customers’ Industry 4.0 platform with remote monitoring and preventive maintenance.

SEYI has successfully delivered SDE servo presses to well-known hot stamped auto parts manufacturer in Japan and the United States, replacing its hydraulic press with the servo press to improve its production process.

SDG series from 4000 to 12000kN are suitable for the automotive metal forming, such as drawing, forming, blanking, punching and cutting for different sizes of metal sheet parts. It satisfies the trend of using high-strength steel to produce lightweight vehicles. SEYI servo presses designed based on the environmental protection mission feature the direct-drive transmission and rigid frame design to reduce the total clearance. SEYI servo motor effectively reduces power consumption and achieves the high torque even at the low speed. The production output can be doubled and save about 50% on electrical power consumption while running progressive dies with Half Motion. Our servo system has 8 motion profiles for customers to use. The hold motion is especially suitable for hot stamping. The vibration motion can support deep drawing for small and large parts. The press can also meet the need of fine blanking. The servo control system also has tonnage monitor and die protection function, increasing the yield rate and extending the tooling lifecycle. SDG series can work independently, actualize the tandem line solution or integrate with different peripheral equipment with high flexibility.

Best choice for large parts forming ─ SLG series are mostly used in automotive industry, mostly for large parts tooling. SEYI has many years of experience in large presses implemented by well-known auto makers such as German’sDaimler. Automation peripherals and quick die change system can be integrated based on customers’ needs.

SLG series features:

• One-piece structure frame made of CSC steel plates, box structure design for the interior frame, and optimization design with finite element analyses to enhance frame rigidity & reliability, preventing the over-design problem.
• Link motion crank-shaft transmission mechanism with main gear and linkage mechanism to enhance the rigidity and reduce the cost, reducing ram speed vibration, noise & over-heating during the forming stroke, and also extending the tooling lifespan.
• The pressure can be relieved quickly when overload thanks to logic valves and small flow rate overload design.
• Machine status is always monitored by PLC and this series featuresDie Sticking Release Device.
• 20% of energy saved by using inverter and fixed speed motor compared with traditional VS motor. The motor speed can be changed by tuning the frequency of the inverter.
• 8-sided eccentric gib design to guarantee the precision and ensure the stamped parts quality.
• Using pneumatic-wet type clutch greatly improves the operational safety. Circulating cooling system with air-cooling cooler to increase cooling efficiency and extend the life of linings.
• Large-tonnage die cushion with locking and adjustment mechanism can deal with different needs either by pneumatic or hydraulic system. Electric control system can control the stroke length and pad pressure precisely with the user-friendly interface.
