Hyson Press Solutions

PRI distributes Hyson cushions and knockout systems for mechanical and hydraulic presses. These products can be quoted for new presses or as retrofit solutions to existing machines. Cushion products available include:

  • Ram Cushions
  • Bolster Cushions
  • Hydraulic Controllable Cushions

Hyson nitrogen and hydraulic cushion designs feature more force in less space, compared to conventional air cushions. Compressors and air consumption are eliminated and surge tanks are often unnecessary.

Hyson offers a wide variety of cushion models and types to suit your specific application.

Hyson Cushions

Hyson Products offers a complete line of press cushions designed for installation in a new press or for upgrading an existing press. Whether the press is equipped with an old cushion or no cushion at all, we can easily retrofit the press to meet both space and performance requirements.

Self Contained Cushions

Hyson self-contained cushion systems

Hyson self-contained cushion systems

Hyson has designed and developed a complete line of self-contained cushion systems. These cushions are closed loop systems and do not need pumps, motors, or compressors.

Benefits:

  • High Pressure- allows customer to fit high force into a small space
  • Adjustable pressure- allows customer to adjust cushion force during tryout and production
  • Delay Capable- allows cushion to delay at bottom dead center to eliminate reverse tonnage

 

Active Hydraulic Cushions

Hyson active hydraulic systems

Hyson offers a complete line of active hydraulic systems. These cushions incorporate a hydraulic power unit which allows customers to gain more controllability and flexibility than the self contained option.

Benefits:

  • Adjustable force profile- ability to adjust pressure on the fly which allows users to fine tune the process
  • Pre- Acceleration- cushion can begin to move before the ram makes contact in order to reduce initial shock.
  • Part Knockout – system can supply a burst of energy to knock part loose from the die
  • Reverse Forming- system can increase force as ram remains stationary to perform a secondary operation
  • Delay Capable- allows cushion to delay at bottom dead center to eliminate reverse tonnage

 

Hyson Knockouts

Hyson Products offers solutions to part knockout problems. Programmable knockout systems provide:

  • Increased knockout force
  • Reduction of set up times compared to manual mechanical knockout systems
  • Knockout timing coordinating with transfer system timing

 

Self Contained Knockouts

The Hyson Knockout System delivers a flexible solution for knockout applications. It is a completely self-contained system and operates without any external hydraulics or other equipment.

Active Hydraulic Knockouts

The Active Hydraulic Knockout System is ideal for applications when more controllability is needed or when the press has reached its maximum force capacity. The system is especially useful when using Advanced High Strength Steels or for deep draw applications.
