Hydraulic Press Manufacturing — Under One Roof
ÖZKOÇ has manufactured hydraulic presses in İstanbul since 1964. Everything happens under one roof at the Hadımköy plant: design, welded-frame fabrication, machining, hydraulic and electrical assembly, PLC/HMI software, acceptance testing and on-site commissioning. The range runs from 70 to 7,000 tonnes; a press is not picked from a catalogue — it is sized to the part.
Why manufacture under one roof?
A press loses its quality not in any single stage but in the handovers between stages: the tolerance of an outsourced welded frame is carried into machining, the assumptions of outsourced software into commissioning. When every stage lives in the same factory, each stage's output is the measured input of the next — and responsibility is never split.
The manufacturing stages
- Design — starts from the part drawing and the process; tonnage, bolster and stroke are calculated and the frame is sized for stiffness.
- Welded frame — bodies are fabricated as a single piece with prepared weld bevels; C-frame (open-gap monoblock) or H-frame (double-upright closed frame) — see the frame-type guide.
- Machining — guide surfaces and the bolster are machined on the stress-relieved body after welding; this is where die parallelism is founded.
- Hydraulic and electrical assembly — cylinder, pump-valve group and cabinet; pressure sets the force, flow sets the speed, and the two are designed independently.
- PLC/HMI software — recipes, speed-force profiles and the safety chain are written in-house; the same team answers when needs change in the field.
- Testing and commissioning — the press is tried under load at the factory, installed and run in production conditions on site, and the operators are trained — after-sales starts here.
What kinds of presses do we build?
Deep drawing, forming, cutting and transfer presses, plus hot moulding presses for SMC/BMC, composites, silicone, brake linings, melamine and ballistic plates — all 16 press families. We serve automotive, defence, cookware, metalworking, construction, healthcare and energy, and export on five continents.
Custom manufacturing: a non-standard request is not a deviation
A request with non-standard tonnage, bolster or process is a design input for us. Even if the press on your floor is another maker's, we inspect the machine in place and tell you what can be done on the hydraulic, electrical and control side. What drives the price is explained in the frequently asked questions.
