Ajax/CECO/Erie Press Fully Hydraulic Die Forgers
Large forgings demand a hammer that delivers repeatable blow energy at full force. The ACE HDF is a high-tonnage hydraulic forging hammer that delivers 200-500 kJ of blow energy, and its separate power station sits on top of the machine, so it needs no extra floor space. Quick-response valves give operators accurate energy control on every blow.
Our engineers at Ajax/CECO/Erie Press work with you to select and configure the HDF for your part and die requirements.

Product Overview
A Heavy-Duty Forging Hammer Sized for Your Largest Parts
Hydraulic pressure builds in separate accumulators inside the oil tank. When a blow starts, the striking valve releases that stored energy into the working cylinder, and the ram drives down. Large dies and heavy billets call for more energy than the smaller hammers in our programmable line can deliver.
A fully hydraulic die forger supplies energy from stored pressure, with no compressed-air supply.
A Separate Hydraulic Power Station That Takes No Extra Floor Space
Elastic location blocks join the hydraulic driving system to the hammer body, and the connecting nuts fix to elastic spacers.
This floor-space-efficient forging hammer also shares valves, motors, pumps, and electrical components with smaller ACE hammers, which simplifies repairs and spare parts planning through our Parts Stocking Program.

A Fully Hydraulic Die Forger With a Long Ram and Wide Guide Rails
Ajax/CECO/Erie Press anchors the guide rails at the top, bottom, and center to prevent vertical and horizontal shifting.
The compound cylinder adds to that stability: its upper end stays fixed while the lower head sways slightly, so seals wear evenly during off-center forging and the piston rod lasts longer.
Those details give this hydraulic forging hammer for large parts the guide stability and seal life that a heavy-duty forging hammer needs.

Match Blow Energy and Guide Clearance to Your Die Set
Start with the die set. Guide clearance sets the space between the guides, so confirm your dies fit before anything else. Then pick the blow energy your hydraulic forging hammer needs for the part. Strikes per minute drop as size climbs, 55 on the 147 HDF and 35 on the 368 HDF, so weigh cycle time against energy.
Total weight and motor power help you plan the foundation and electrical supply. Compare every figure in the Hydraulic Die Forgers brochure, then send your die dimensions and part weight through our quote form.
Heavy Industrial Die Forging Equipment With Integrated Safety Features
Die changes put crews closest to the machine. Ajax/CECO/Erie Press builds this heavy industrial die forging equipment to release pressure and secure the ram before anyone steps in. Each HDF includes the following safety features:
- Slow ram movement: The ram moves slowly up and down, which releases hydraulic system pressure before a die change.
- Ram interlock: The interlock holds the ram in place while crews change dies.
- Pressure feedback safety stop valve: If a piston rod breaks or comes out for replacement, this valve stops high-pressure oil from spraying.
- Inch mode interlocks: On larger hammers, only the working cylinder discharges oil. Hydraulic and electrical interlocks on the striking valve allow inch mode once the accumulator reaches system pressure.
- Integrated accumulator and pipeline design: The accumulator and pipeline assembly share one integrated safety design.
