Most of the press plants are multi- opening plants having 10 - 30 daylights. Per daylight 12 - 16 laminates are loaded with the according number of press plates. This results in high capacities, but also in low flexibility in view of different surface finishes and short delivery times, since the individual press plates are available every 2 h only for a new load.

A relative new type of press plant is represented by a 6-opening press having a load per daylight of 4 - 6 laminates and 3 press plates. Based on short cycle times and large board dimensions the capacity is high and the flexibility as well.

This plant type requires a substantially lower number of press plates/finish. The plates are available every half an hour for a new load.

The latest development is the single- opening press plant without cooling system having a load per daylight of 2 laminates and 2 press plates. Caused by large laminate dimensions the capacity is reasonably high and the flexibility to orders is remarkable.

This plant type has the lowest plate costs, since 2 press plates/finish are required only. With this plant type the plates are available permanently, i.e. the orders can be executed quickly.
