CNC workholding
Reduce idle running after clamping while supporting the machining hold.
Explore the solution →APPLICATIONS / DUTY FIRST
Hydraulic power unit case studies. Real machines.
From machine-tool workholding to casting and packaging, we apply intermittent pressure holding to different production cycles to help customers reduce energy use and heat.
APPLICATION SOLUTIONS
Start with your application.
Casting fixtures
Plan around long holds, ambient heat and maintenance needs.
Explore the solution →EPE forming
Separate pressing, holding and return motion to reduce holding energy.
Explore the solution →APPLICATION CASES
The holding phase makes the difference.
See how we help machining, casting and packaging equipment cut holding energy, reduce oil temperature and improve day-to-day operation.

Explore the retrofit ENERGY INTO VALUE
Less idle running. More value.
Make each holding phase count. Stop the motor after motion, then recharge when pressure reaches the set threshold, reducing energy use and heat from continuous idle running.
Save 75% or more in short-motion, long-hold applications. Turn reduced electricity use into lower running costs and get more value from every clamping cycle.

Review the savings potential of your machine →Machine-tool clamping & holding
For chuck, tailstock and turret actions that require pressure holding.
Prioritise these RFQ inputs
- Motion sequence and cycle time
- Working pressure and flow
- Hold time and allowed variation
Automation & workholding
For hydraulic actions in fixtures, pressing, test rigs and special-purpose lines.
Prioritise these RFQ inputs
- Peak load and duty cycle
- Installation envelope and orientation
- Ports, controls and power supply
Machinery OEM integration
For repeat machine platforms confirmed through controlled configurations and project documents.
Prioritise these RFQ inputs
- Target machine and demand direction
- Drawings, BOM and revision control
- Destination documents and standards
MEASUREMENT METHOD
Measure → configure → re-test on the same boundary
Record the current machine and a stable duty cycle, then select a direction around load, dynamics, installation and budget. Re-test pressure, flow, energy, temperature rise and exceptions on the same boundary.Review the product boundaryHow to use these hydraulic retrofit examples
Start with the CNC hydraulic case study, casting fixture case or EPE forming case that resembles your process. Compare pressure holding projects by motion, holding time, interfaces and retained equipment. Customer case conditions provide a discussion basis, not a guarantee that the same unit or savings will apply to another machine.
