There is advanced technology and experience of years behind the GABROVNICA chipboards, which became numer one in demand with its quality in Bulgaria and many other countries in the world. The wood raw material first cut into chips in chipping machine, and then taken into wet chip silos. The chips dried in the dryers are sorted and top and medium layer chips are stored in separate silos. Later they are mixed with glue and other chemicals and the spreading machine, which spreads the top, roughly forms the board and medium layers on the belt and then produced as boards by press machine under heat and pressure. Then, cooling, sizing and piling processes are performed. After leaving for test 1-3 days for conditioning, the boards are sanded and prepared for sale.
