This is the lowest-priority, highest-risk card in the set, and it belongs last for a reason. It is capital-heavy and it only pays under narrow conditions. The idea is sound: an all-electric press uses servo motors to move the screw and clamp instead of a hydraulic pump that runs continuously, so it draws far less power, cycles faster and more repeatably, and makes less scrap. On the oldest fixed-pump hydraulic presses in the shop, an all-electric replacement can cut energy per part by 30% to 70%.
Deep dive
Expand for detail
Load-bearing, card breaks if wrong
The presses being converted are old fixed-pump hydraulics, not modern VFD machines.
The whole energy case rests on replacing an old, continuously running hydraulic pump. Against a modern variable-speed hydraulic the saving is a fraction of the headline. What it looks like on the floor if this is wrong: the metered energy per part barely drops after conversion because the old press was not that wasteful. Meter kWh per part on the candidate press first.
The converted press runs high hours.
Energy, cycle, and scrap savings all scale with run-hours. On a low-duty press the annual saving is too small to return a $120K machine. What it looks like on the floor if this is wrong: the new electric press sits idle much of the week and the payback stretches past its life. Check press utilization before converting.
This is done as retire-and-replace, not a fleet swap.
The case only works when the old press was going to be replaced anyway, so the incremental cost is the electric premium, not a whole new machine bought early. What it looks like on the floor if this is wrong: serviceable hydraulics get scrapped early to buy electrics, and the capital never comes back. Only convert machines that are both worn out and running hard.
Supportive, card weakens but survives
No utility rebate is needed for the case.
Because Ohio has no rebate to count on after HB 6, the base case assumes zero. What it looks like on the floor if this is wrong: someone budgeted an incentive that no longer exists. It is built to pay on energy, cycle, and scrap alone, with depreciation as the backstop.
Risk
Converting serviceable hydraulics, or any press early, spends $100K to $200K a machine that the energy saving never returns. Payback on energy alone is three to six years even on a good job.
Early Warning
New electric presses being bought while the hydraulics they replace still had years of life.
Mitigation
Convert only machines that are both worn out and running high hours; one at a time, tied to real retirements.
Stake
$100K to $200K per press of capital that never comes back.
Risk
The 30% to 70% energy saving is against old fixed-pump hydraulics; against a modern or VFD-equipped press the saving is a fraction of that, so the payback stretches out.
Early Warning
Metered energy per part barely drops after conversion.
Mitigation
Meter kWh per part on the candidate before committing; skip presses that are already efficient.
Stake
The payback doubling from three years to six or more.
Risk
Converting to electric while air leaks and over-run dryers remain means you are spending big capital to cover waste you could have fixed cheaply.
Early Warning
The energy card's leak and control fixes are still open.
Mitigation
Do the cheap energy fixes first; then convert.
Stake
$20K to $50K a year of easy saving skipped for a capital-heavy one.
Risk
An electric sized to one part may not cover the full job mix that press runs, leaving it unable to hold parts it was bought for.
Early Warning
The new press cannot run some of the jobs the old one did.
Mitigation
Size to the press's job mix, not a single part; confirm shot size and tonnage before buying.
Stake
Stranded capital on a press that cannot do its work.
A hydraulic press runs a pump motor at full speed the whole cycle, using pressurized oil to move the screw and clamp. Much of that energy is wasted as heat, and the machine keeps drawing power through cooling and hold when it needs no flow. An all-electric press uses servo motors that turn only when and as hard as the motion needs. That is where the 30% to 70% energy cut comes from, plus faster and more repeatable moves (which add throughput and cut scrap on a high-run job). The trade is a higher sticker price.
This is the single rule that keeps the card from losing money. Do not go buy a fleet of electrics. Wait until a worn old hydraulic on a high-run job reaches the end of its life, when you were going to buy a replacement press anyway, and make that one replacement an all-electric instead of another hydraulic. Then the money at risk is only the premium over a hydraulic, not a whole machine bought early. One press at a time, only on high utilization, because the savings scale with run-hours.
Here is the mistake that turns a three-year payback into six. The headline 30% to 70% energy saving is measured against old fixed-pump hydraulics that run the motor flat-out. If the press you are eyeing already has a variable-speed drive (from the energy card), most of that saving is already captured, and the electric conversion adds far less. So the two cards interact: a VFD retrofit and an all-electric conversion are partly substitutes on the same machine. Meter the actual energy per part on the candidate before you commit, so you know which saving you are really buying.
Two closing cautions. First, do the cheap energy fixes (leaks, dryer and chiller controls, barrel blankets) before spending six figures on a press, or you are buying capital to cover waste you could have fixed for a few thousand dollars. Second, as with the energy card, Ohio has no utility rebate to count on after House Bill 6, so the base case assumes zero incentive. The reliable backstop is federal depreciation (MACRS, with qualifying equipment currently eligible for 100% first-year bonus depreciation restored by the 2025 federal tax law; confirm with a tax advisor), which applies regardless. Anything a utility rep can still find is a bonus on top, never the reason to buy.
