243 types of wooden and metal moulds can be used for pressing purposes. In case of external customers´ serious interest, a custom-made mould can be produced for their own shape. The pressing process can be divided into two technological procedures - high frequency stiffening, or by using steam. High-frequency Presses can hold larger forms - and the final appearance resembles grown wood due to the way the veneers are layered. This technology works on the principle of a microwave oven – the vibration of a material´s molecules heat it up and cause the condensation of the glue, thereby stiffening the pressing. Steam Presses are usually used for smaller types of plywood, like seats or rests. Metal moulds are used in these cases.
