Different with continuous line, the NT-PUSP-D PU discontinuous production line is actually divided into three parts: roll forming machine (or bending machine), PU press machine and PU injection machine; it produces sandwich panel piece by piece.

The sandwich panel size is decided by the mould board, which normally has 6.5/ 8.5/ 12.5 mts x 1/1.5 mts; and its capacity is depended on PU press machine structures, which mainly includes: 1+1, 2+2 or multi-layers. Among them, the NT-PUSP- 6.5x1.5/ 2+2 is one of the most popular models.
