KOH-I-NOOR RONAS s.r.o.In 1992, the company RONAS, as well as other thirteen companies, split from the holding TESLA. Originally, TESLA was located in the city Rožnov pod Radhoštěm and focused on the production of black and white and colourful television screens and on the production of various electronic components. The market experienced significant changes since the foundation of the company RONAS s.r.o. However, RONAS successfully managed to adapt to these changes and experienced a very dynamic development. The company is the holder of important certificates such as ISO 9001, IATF 16949 and of the Environmental Management Certification ISO 14001.

KOH-I-NOOR RONAS is divided into two divisions -  tool - shop department  and  injection moulding department.


Complex Solution

The company KOH-I-NOOR RONAS has extensive experience in the field of injection moulding and, therefore, it can offer comprehensive services including the development of a moulding, structural design of a mould as well as its moulding and assembly. The moulds for external companies are tested in our company and, consequently, we recommend our clients suitable solutions for series production moulding. Moreover, our clients can count on professional maintenance and repair service.  There are many important automotive industry suppliers located in the Czech Republic and, therefore, KOH-I-NOOR RONAS sells 60% of its production to the domestic market. Moreover, the company has established a firm business relationship with Germany.
