Electric Screw Press for Hot Forging
The electric screw press is a multi-purpose forging equipment that combines the advantages of general presses and forging hammers. It features a simple structure, compact footprint, short transmission system, easy operation, safe running performance and low maintenance cost.
This machine is applicable to multiple forming processes such as precision forging, finishing, coining, embossing and flattening.
Its impact energy can be precisely adjusted based on mold accuracy. This shortens the duration of mechanical stress and reduces contact time between hot workpieces and dies, thereby extending mold service life.
Equipped with a rigid frame, the press delivers excellent guiding performance and great resistance to eccentric loads, making it suitable for multi-cavity die forging. It is an energy-efficient and eco-friendly forging press.
◆ Split cast steel frame pre-tensioned with tie rods delivers exceptional structural strength and overall rigidity.
◆ The machine adopts reinforced construction paired with a dedicated switched reluctance motor featuring outstanding overload capacity, high starting torque and low startup current.
◆ A built-in overload protector is integrated into the transmission system to guarantee operational safety.
◆ Fitted with extended X-type reinforced guide rails that maintain high precision and powerful anti-deflection performance under heavy eccentric loads.
◆ Fitted with extended X-type reinforced guide rails that maintain high precision and powerful anti-deflection performance under heavy eccentric loads.
◆ Servo direct drive motor configuration is available as an optional upgrade.

Electric Screw Press – Features & Advantages
Diverse Frame Options
We provide customized frame solutions including integral cast frames, integral welded frames and pre-stressed split welded frames. Tailored designs are available to satisfy customers’ different layout space and automated production demands.
Superior Structural Rigidity
The frame structure is optimized and validated via finite element analysis. Key components feature reliable strength with a compact and well-proportioned overall layout.
X-shaped guide rail and long slider structure
The machine boasts high lateral and overall rigidity together with precise slider guidance and outstanding anti-eccentric load capacity, enabling multi-cavity forging. Lead screws and nuts are machined by high-precision CNC machine tools for superior fitting clearance, ensuring stable energy output from both control and transmission ends.
Higher Energy Efficiency & Intelligent Control
The control system integrates control, real-time display, fault pre-warning, operation monitoring, remote access and OEE data analysis, compatible with multiple operating platforms. Seamless single-unit operation or full automated line connection can be effortlessly achieved.
Reliable Safety Performance
Fitted with flywheel mechanical overload protection. The friction slip overload mechanism ensures stable and safe operation.
Energy Saving & Low Noise
Low vibration and low noise design meets eco-friendly standards, making the press highly adaptable to automated production lines.
Electric screw press working principle
The slide moves up and down, driven by the motor via the pinion, gear wheel and screw mechanisms. The gear wheel possesses sufficient inherent inertia and acts as a flywheel.
Upon receiving a start signal, the motor accelerates the slide downward from a stationary state through the pinion and gear wheel transmission. Once the slide reaches the target speed matching the preset blow energy, the motor terminates acceleration.
The kinetic energy stored in the gear wheel is released to complete workpiece forming.
Simultaneously, the motor immediately drives the gear wheel into reverse rotation. When the slide reaches the preset position, the motor initiates braking and returns the slide to its original position.
Since the return stroke is braked by the motor, the mechanical brake only functions when the slide approaches the top dead center. This greatly reduces wear on the brake components and lowers replacement frequency.
