Kosinus Muhendislik

What Kosinus Muhendislik does

Kosinus Muhendislik (operating as Cosinus Engineering) is a privately held precision engineering and custom manufacturing firm headquartered in Pendik, Istanbul, Turkey. With a headcount of eight, the company operates a modern machine park and offers end-to-end services spanning engineering design consultation through to production and delivery. Its portfolio is diversified across five principal product categories: energy-sector connection elements (bars, diameter products, flexible/woven busbars), mechanisms, miscellaneous engineered products, industrial cabins (compressor cabins and telescopic masts), bathroom and furniture accessories produced under private-label arrangements, disability support products manufactured for multiple brands, and high-strength steel construction components.

The business model is project-based custom manufacturing sold directly to B2B clients through a quote-driven sales process. Customer inquiries trigger in-house technical analysis, after which tailored engineering solutions and pricing are provided; production proceeds upon approval, with expedited options for urgent orders. The company serves multiple end markets — energy sector firms (primary vertical), industrial equipment manufacturers, bathroom/furniture brands, and accessibility solutions brands — without publicly disclosed pricing, named customers, or revenue figures. It holds ISO 9001 quality management certification and operates with a Turkish-language primary website supported by an English version, suggesting at least limited international intent.
