The main profile of  Kokai Ltd. are the so called rubber-only, metal-rubber and plastic-rubber parts.


The high-tech production machinery is endorsed with high quality pre- and post-production capabilities. The parts are produced by traditional press (compression moulding) and injection-moulding technologies through 160-240 tons IM and 160-400 tons CM machines.
Kokai is sourcing raw materials mainly from its Hungarian partners, with the only exception of special raw materials and post-production capabilities that are not possible to source from within Hungary. All parts produced are finished and visually checked in-house in order to assure continuous high quality.
The basis for delivering continuous high quality is the set of measuring equipments the company owns and operates in-house. More information about our measuring capabilities available here. (link to Quality)

Since January 2015 Kokai Ltd. further developed its raw material and prototype-delevopment capabilities. With the extension of the measurement equipments necessary to support this kind of activity, Kokai is now even more efficient and capable to cooperate with its partners in development projects.
