Transform Your Pneumatic Press Operations with Intelligent Electro-Pneumatic Proportional Valves


In stamping, molding, and assembly processes, pneumatic presses deliver critical force for mass production. However, abrupt pressure changes during tool engagement often cause destructive vibration, premature component wear, and inconsistent product quality. Our electro-pneumatic proportional valves redefine press performance by enabling real-time force modulation, adaptive staging, and smart automation – all while slashing maintenance costs.

The Hidden Cost of Fixed-Pressure Pneumatic Presses

Traditional press systems face three key challenges:

  1. Impact Shock: Sudden full-pressure engagement damages tooling and base frames.

  2. Overcompensation: Operators manually overshoot pressure to ensure part seating, wasting energy.

  3. Wear & Tear: Cyclic stress from pressure spikes reduces seals, cylinders, and bearings by up to 50% faster.


Our proportional valve technology eliminates these issues through:

1. Two-Stage Intelligent Pressure Control

  • Pre-Contact Phase: Apply 10-30% rated pressure for gentle tool alignment, eliminating misalignment crashes.

  • Engagement Phase: Ramp to 100% pressure in <50 ms for full-force stamping/molding.

  • Retraction Phase: Maintain 15% backpressure to prevent workpiece rebound.

2. Vibration Suppression Algorithm
Proprietary PID logic reduces press frame oscillation by 72% via:

  • Predictive pressure damping during direction changes

  • Shock-absorbing pressure curves tailored to tool weights (0.5-500 kg)

  • Instantaneous pressure stabilization (±1.2% FS)

3. Remote Automation Integration

  • PLC Programming: Set pressure profiles via Siemens TIA Portal, Rockwell Studio 5000, etc.

  • IoT Readiness: Monitor press cycles and valve health via OPC UA/MTConnect.

  • Safety Interlocks: Auto-reduce pressure if tool sensors detect obstructions.


Case Study: Automotive Bracket Stamping
A Tier-2 auto parts supplier achieved:

  • 41% Longer Tool Life: Reduced peak impact forces from 12kN to 4.8kN

  • 18% Energy Savings: Eliminated constant 100% pressure standby mode
