02About us
Founded in Bursa in 1998, ÇAĞSEV Automotive's success story began with two automatic lathes. Following technology and innovation closely and investing more every year, we continuously renew our machinery: a broad machine park of CNC Swiss-type lathes, CNC lathes, thread rolling, tube cutting, cut-to-length, milling, turret lathe, tapping and column drilling machines.
Growing with due care for people and the environment, and expanding its market share through customer-satisfaction and quality-focused policies, ÇAĞSEV has reached a monthly production capacity of 2,000,000 parts for the tier-1 suppliers of major vehicle manufacturers such as TOFAŞ, RENAULT, TOYOTA, FORD, NISSAN and HYUNDAI. We operate on a total production area of 1,400 m², 1,150 m² of it indoors.
Alongside automotive parts, we provide machining services to the home appliance, machine building, medical, furniture and heating-cooling industries, and have become one of the leading companies in the sector.
In addition to the domestic market, we export to international markets, primarily Romania, serving our international partners with consistent quality and on-time delivery.
