Refurbished FRECH DAW 125 F Die Casting Machine Completed
Following extensive mechanical, hydraulic and electrical work, the fully refurbished FRECH DAW 125 F was successfully tested, completed and delivered to the customer.
Which die casting machine was completely refurbished?
The machine refurbished was a FRECH DAW 125 F die casting machine. It was completely cleaned, mechanically and hydraulically inspected, rebuilt with renewed components and subjected to a successful final functional test.
After all work had been completed, the machine was finalised and delivered to the customer.
More than a cosmetic refurbishment
During the refurbishment, key mechanical, hydraulic and electrical assemblies were dismantled, inspected and, where necessary, repaired or renewed.
The aim was to provide a technically reliable machine with verified tolerances, operational interfaces and fully tested control and hydraulic systems.
Inspection of the locking unit
The locking unit was dismantled, inspected for wear and precisely realigned after refurbishment.
Inspection and renewal
Hydraulic cylinders, valves, the pump, pipework and seals were inspected and partially renewed.
Testing and modernisation
The control system was tested and the operating terminal was upgraded as part of the refurbishment.
Which functions and interfaces does the machine offer?
The refurbished FRECH DAW 125 F features interfaces and functions for automated production processes and additional die movements.
Digital extraction interface
A digital interface enables connection to an external part-removal system.
- Compatible with a pick-and-place unit
- Robot connection possible
- Integration into automated processes
- Coordinated component removal
Integrated weighing system
The integrated weighing system can be used for control within the production process.
- Weight measurement within the system process
- Support for process monitoring
- Integration into the machine function
- Additional quality control
Spray mat unit
The existing spray mat unit supports automated treatment of the die.
- Automated die treatment
- Integration into the machine cycle
- Repeatable spraying sequences
- Reduced manual intervention
Multiple core-pull functions for demanding dies
The core-pull system expands the die functions and enables additional controlled movements during the casting cycle.
Core feed on the fixed and moving sides
The machine is equipped with one core feed on the fixed platen and at least two core-pull devices on the ejector platen.
From dismantling to the final functional test
The work was carried out in coordinated stages so that all relevant assemblies could be inspected, repaired and subsequently tested.
Cleaning
The machine was completely cleaned inside and outside. The hydraulic tank was also cleaned.
Dismantling
The locking unit, injection system, ejector and cylinders were dismantled for inspection.
Repair
Wear parts, seals, distributors, pipes and other components were renewed or refurbished.
Assembly
All machine groups were reassembled and precisely aligned with one another.
Final inspection
Following repainting and completion, the machine successfully passed its final functional test.

Verified tolerances and machined platen surfaces
The locking unit was completely dismantled and inspected for wear.
The tolerances of the tie bars and bushings were inspected. A value of less than 0.15 mm was confirmed. The surfaces of the fixed and moving platens were also milled.
Dismantled locking unit
The relevant components were made accessible and inspected before reassembly.
Less than 0.15 mm
The inspected tolerances of the tie bars and bushings were within the confirmed range.
Newly machined surfaces
The surfaces of the fixed and moving platens were milled as part of the refurbishment.
Inspected cylinders, valves and hydraulic pump
The hydraulic system was a central part of the refurbishment. The tank, pump, valves, cylinders, seals, distributors and pipework were inspected.
The hydraulic ejector and locking cylinder were dismantled and fitted with new seals. Bosch Rexroth valves were also refurbished.
Dismantled and resealed
The injection system was inspected and subsequently rebuilt with new seals.
Hydraulically refurbished
The hydraulic ejector was dismantled, inspected and fitted with new seals.
Inspected and resealed
The locking cylinder was also dismantled, inspected and fitted with new seals.
Valves and pump inspected
The hydraulic valves and hydraulic pump were tested. The Bosch Rexroth valves were refurbished.
Renewed pipework and upgraded operating terminal
In addition to the main mechanical and hydraulic assemblies, the central lubrication system and the operator interface were also refurbished.
System fully inspected
The function of the central lubrication system was inspected to ensure reliable supply to the lubrication points.
Components renewed
Distributors within the lubrication system were replaced during the refurbishment.
Pipe network replaced
The associated pipework was replaced with new components.
Operating terminal upgraded
The existing operating terminal was modernised and the control system was subsequently tested.
Precise alignment and successfully completed functional test
After the individual refurbishment stages had been completed, the machine groups were reassembled and aligned with one another.
The machine was then prepared for painting, completely repainted and subjected to a final functional test, which it successfully passed.
- Assembly of all machine groups
- Precise alignment of the assemblies
- Inspection of mechanical movement sequences
- Testing of hydraulic functions
- Verification of the control system
- Preparation of the machine surfaces
