About us —
Three generations, one passion.
A journey that began in a small workshop in 1961 continues today in four factories and thousands of machines running around the world.
Kocayusuf, past to future
Kocayusuf was founded in 1961 by Yusuf Ziya Güleray in a small workshop in Istanbul, and is today a family company run by its third generation.
The second generation — the founder’s engineer sons — carried the master’s experience one step further, and today the third generation has taken up the flag. Producing in 3 factories with a total of 18,000 m² of covered area in Y. Dudullu and Dilovası OIZ, together with its 4th factory in Bursa that opened in 2024, Kocayusuf always aims for customer satisfaction and quality, with thousands of machines in operation.
