- The Force Modulator™ is a hydraulic part-holding system used in press draw operations. It is used as a cost beneficial replacement of nitrogen cylinders and press die cushions.

- The Force Modulator™ system addresses the following costly problems common to stamping operations:
1. Aluminum and high strength steel parts are dramatically improved since the system has the ability to increase and/or decrease tonnage throughout the stroke. This also allows for blank size optimization.
2. Significantly reduces impact shock.
3. Reduces return shock through controlled piston and binder ring return.
4. Controlled return speed maintains part stability within the die, allowing for improved line yield and productivity.
5. Downtime is reduced through minimization of shock and cylinder reliability.
6. Optional Hold-on-Bottom-Valve delays return stroke for automation or transfer requirements. This also reduces part inversion.

- The Force Modulator™ System is currently used in production throughout the automotive and appliance industries.

- Hydraulically crimped SAE fittings provide a consistent ferrule hold, eliminating the human error that occurs with hand crimping.
- The use of a manifold reduces the number of possible leak points throughout the system.
- Cylinder construction includes a special bushing material, chrome plated rods, and a rod wiper, in order to reduce the possibility of leaks.

- Depending on die specifications, most cylinders can be easily serviced by removing the binder.
- All ancillary equipment can be mounted either directly to the die, or to a mounting unit located outside the press. This allows for ancillary service without ever having to open the die.

- The Force Modulator™ is built around a specified number of proprietary hydraulic cylinders. As the press cycles, the piston is driven down while ejecting fluid from the cylinder into a nitrogen charged accumulator. During upstroke, the nitrogen pressure causes fluid to drive the cylinders up.
- The tonnages of the Force Modulator™ cylinders are speed sensitive. Typical speed range is +/- 20% of nominal design speeds. For example, the faster the speed the higher the tonnage.

- Typical system deliveries have been between 8 and 10 weeks. This is from Purchase Order date to system delivery.

- Each system is engineered to meet the requirements of a specific die. Costs will vary depending on the size and complexity of each installation. A typical system using twenty cylinders, each cylinder having a five ton capacity, will cost approximately $100,000. This cost is a general guideline. For a die-specific quote, please contact us and complete an Engineering Quotation Request.

- Provided the alternate press speeds match design parameters there should be no problem running this system in a different press.
- The Force Modulator™ can be used in hydraulic presses when tonnage needs to either be increased or held constant.
