After Sales

When the press is delivered, the job is not over.

The economic life of a hydraulic press runs to decades. We commission the presses we build on site, train the team that will use them, and meet maintenance, breakdown and modernisation requests throughout the life of the machine.

Request Service
  1. 01CommissioningInstallation of the press on site, checking of the hydraulic and electrical connections, and running it under production conditions.
  2. 02Operator trainingOn-site training for the team who will use the machine, covering operation, setting and safety rules.
  3. 03Breakdown responseOn notification of a stoppage, our technical team responds remotely or on site.
  4. 04Overhaul and modernisationRenewal of the hydraulic, electrical and control systems of older presses that are still in service.
  5. 05Spare partsSupply of original parts specified in the press’s own project.
  6. 06A solution for an existing machineWe examine the machine in place and explain what can be done on the hydraulic, electrical and control side.
  7. 07A solution for the production processWe assess your part, your die and your existing line together, and produce press and automation solutions that will improve your production process.

From the first quotation to years afterwards

The relationship begins with a quotation: we talk through your part, your material and your cycle target; the technical quotation is prepared with tonnage, bolster and stroke figures. Design, frame manufacture, hydraulic and electrical assembly, software and acceptance testing all run under one roof — your contact does not change at any stage in between.

The file does not close once the press has been installed and commissioned on site and your team has been trained. The economic life of a hydraulic press runs to decades, and throughout that time maintenance, breakdowns, spare parts and modernisation are handled from the same place. When you ask for a spare part, we hold the record of which project the press was calculated for and which part was fitted; older presses still in service go back into production after their hydraulic, electrical and control sides have been renewed. In other words, the relationship is measured not by a sale but by the life of the machine.

Why an original part

  • On a hydraulic press the cylinders, valves and sealing elements are selected according to the tonnage of the press and its cycle regime.
  • An equivalent part may work in the short term.
  • But it can change the cycle time, the oil temperature and the behaviour of the safety functions.
  • For a spare part, we hold the record of which project the press was calculated for and which part was fitted.

Common faults and the first check

The symptoms below are the ones most often reported on hydraulic presses. The first check is limited to what can be done without stopping the machine; a fault is never traced by disabling a safety function.

Pressure does not build, tonnage is short
The oil level, the suction strainer and the pressure control valve are checked first. If the pump sound has changed or the pressure drops under load, the pump or the relief valve is examined.
The ram does not hold its position, it drifts
The cylinder seals, the pilot-operated check valve and a leak in the lines are the first suspects. Drift under load is a safety matter; nobody goes under the ram.
Oil temperature is rising
Hydraulic oil ages rapidly above 60 °C. The cooler, the oil level and viscosity, a blocked filter and running at high pressure while idling are checked.
Leakage
The hoses, the fittings and the cylinder seals are checked in that order. If the location of the leak and the colour of the oil are sent as a photograph, diagnosis is faster.
The press does not start, it shows a fault
The safety circuit — emergency stop, light curtain and door switch — and the fault message on the HMI are read. A fault is never traced by disabling a safety element.
Noise and vibration
Air in the suction line (cavitation), a low tank level and a loose connection are the most common causes; the pump sound should be recorded from the first moment.

Periodic maintenance

The intervals depend on the number of cycles, the oil quality and the ambient temperature; contact us with the serial number for the maintenance plan of your own press.

Every shift
Oil level and leak check; testing of the emergency stop and the light curtain; abnormal noise.
Weekly
Oil temperature, filter clogging indicator, lubrication of the columns and guides.
Monthly
Hoses and fittings, control cabinet fan and filter, tightness of the electrical connections, bolster parallelism.
Annually
Oil analysis or oil change, filter replacement, accumulator nitrogen pressure where fitted, seal condition and verification of the safety circuit.

Frequently asked questions about service

Which presses do you service?

On the presses we build ourselves we work from the drawings and part records of the project. On presses from other manufacturers we examine the machine in place and explain what can be done on the hydraulic, electrical and control side.

What happens when we report a breakdown?

When you report it, we take the serial number, the symptom and the fault message on the HMI. Diagnosis is made first by telephone or remotely; if necessary a site visit is planned and the parts needed are identified in advance.

Where do you provide service?

The factory and service centre are in Arnavutköy, Istanbul. Commissioning, operator training and on-site response take place at the plant where the press is installed, in Turkey and in the countries we export to.

Can you modernise our old press?

Yes. On older presses that are still in working order the hydraulic, electrical and control systems are renewed; the frame is kept, and the press returns to production with up-to-date safety and control equipment.

What do we need for a spare parts order?

The serial number on the machine plate, the year of manufacture, the name or position of the part and a photograph. Since we hold the record of which project the press was calculated for and which part was fitted, the match is made from there.

Can we use an equivalent part?

The cylinders, valves and sealing elements are selected according to the tonnage of the press and its cycle regime. An equivalent part may work in the short term; but it can change the cycle time, the oil temperature and the behaviour of the safety functions.
