Many presses appear to be running at full speed, yet production output still falls short of expectations. The machine cycles and parts are made, and nothing seems obviously wrong. But over time, small inefficiencies inside the hydraulic system can quietly slow the entire operation.
For technicians, increasing throughput is rarely about forcing the press to run faster. It is about removing hidden limits that prevent the machine from operating at its true capability. Small delays in motion, energy losses, or control settings that are too conservative can add seconds to every cycle. Those seconds add up across thousands of parts.
Below are several places technicians should look first when trying to increase press throughput.
Check for Artificial Speed Limits in Control Tuning
- Review motion profiles and acceleration settings.
- Identify conservative tuning changes made during past troubleshooting.
- Check whether pressure ramps or speed limits were reduced to stabilize past issues.
- Verify that current tuning reflects the actual load and tooling conditions.
- Remove unnecessary speed limits once the system is stable.
Look for Hidden Dwell Time in the Cycle
- Observe the press cycle carefully for small pauses between movements.
- Watch for delayed valve response when direction changes occur.
- Check for internal valve leakage that slows pressure buildup.
- Look for cylinders drifting slightly before the next motion step begins.
- Measure cycle timing to identify dwell periods that operators may not notice.
Watch for Thermal Derating During Long Runs
- Monitor hydraulic oil temperature during extended production runs.
- Identify situations where motion slows as the system heats up.
- Check whether pumps or drives reduce output to protect components.
- Inspect cooling systems such as heat exchangers and fans.
- Stabilizing temperature often restores consistent cycle speeds.
Compare Press Behavior Across Shifts
- Observe how the press behaves under different operators.
- Compare cycle times between shifts running the same parts.
- Identify operator adjustments that affect speed or motion profiles.
- Check whether different production loads create inconsistent motion.
- Standardize operating settings so performance stays consistent.
Identify Energy Losses That Slow Motion
- Inspect pumps, valves, and piping for internal leakage.
- Monitor pressure stability during high-load motion.
- Check for restrictions that reduce available flow.
- Look for worn components that waste hydraulic energy.
- Energy losses often appear as slower movement rather than obvious failures.
Throughput Improves When Hidden Limits Are Removed
Most presses are capable of producing more than they currently do. The challenge is finding the small inefficiencies that quietly extend cycle times.
By reviewing control tuning, identifying hidden dwell time, monitoring temperature effects, comparing shift performance, and locating energy losses, technicians can remove the barriers that slow production.
When these issues are addressed, presses often increase throughput without adding risk or overloading the system.
The Takeaway
Improving press throughput often requires a deeper understanding of how hydraulic systems behave under heavy production loads. Partnering with The Oilgear Company gives maintenance teams access to specialists who focus on high-performance hydraulic presses and power units.
Through system assessments, motion analysis, and targeted upgrades, Oilgear helps teams identify hidden inefficiencies that limit production speed. These may include control tuning constraints, internal hydraulic losses, thermal limitations, or component wear.
By addressing these issues at the system level, teams can increase throughput while maintaining safe and stable press operation—allowing machines to produce more parts without increasing risk to equipment or operators.
