JH21-45T Series High Precision Pneumatic Power Presses

JH21-45T Series High Precision Pneumatic Power Presses

The high performance hydraulic plate Bender is an essential tool for metalworkers and fabricators who need to bend sheet metal precisely and efficiently.

Advantages of high performance hydraulic plate Bender

  • Increased productivity: Metal workers and fabricators can bend sheet metal quickly and efficiently with high-performance hydraulic sheet benders. This increases productivity and reduces project turnaround time.
  • Improved Quality: The precision and accuracy of the high performance hydraulic plate Bender improves quality, with consistent and uniform bends to tight tolerances.
  • Reduced Operator Fatigue: The hydraulic drive system and user-friendly control panel reduce operator fatigue, allowing them to work more efficiently and comfortably.
  • Low Maintenance: Minimal maintenance is required, reducing downtime and costs and ensuring consistent and reliable performance.

High performance hydraulic plate Bender main features

1、High Rigidity

High rigidity, high-precision frame, with welded steel board and heat treated, eliminate inner tension of press.

2、Balance Center Of Gravity

The transmission center is in accordance with the center of the whole machine, ensuring accurate and

stability in pressing.

3、Safe and Reliable Operation

High-sensitive clutch/braking added international top double electromagnetic valve and overloading protection

device can guarantee the accuracy and safety for slid board running and stopping.


The abrasive sections of the crankshaft, gears and gear shaft are treated by hardening heat treatment and followed

milling processing, with high abrasion resistance and balance performance, as well as stable performances.

Ensure quality and use life of Punch.

5、Automation Processing

Can equip all automatic feeders for automation production, reduce the cost, and promote efficiency.
