The company KOVINSKI IZDELKI Hrast s.p. was established in the year 1984 and was registered in Borjana, municipality of Kobarid. Production programme includes the whole range of machining of metal (CNC turning on the lathes, milling, drilling, grinding) on the classic and CNC automated lathes. In 2002 we established Soca valley cluster with 5 partner companies (www.pkg.si).

We are producing different assembly parts and finishing semi-finished products (wrought-iron) used by the car industries on multi-spindle automated lathes and CNC turning lathes. Due to enhanced requirements of customers and for better penetration on the foreign markets, we succeeded in obtaining the quality certificate ISO9001-2000 and ISO14001:2004.

With very high level of knowledge and experience, with up-to-date equipment and technological resources we are manufacturing:
• machining on classic automated lathes up to the diameter of 28 mm,
• machining on multi-spindle automated lathes up to the diameter of 30 mm,
��� machining on CNC automated lathes (turned milled parts) up to the diameter of 42 mm,
• machining on CNC long turning lathes up to the diameter of 20 mm
• swiss turning (micro turned parts) on CNC (Citizen) lathes from bar diameter 1 mm
• all finishing operations (heat treatment, surface protection...), necessary for different specific products.
