HPL Continuous? More Power for Laminate Manufacturers, 2002 Decorative and Industrial Laminates Symposium
The isobaric double belt press (DBP), which permitted the continuous production of thin laminate, has come a long way since it became a reality in 1975. By today, continuous development work has made the tiny first machine providing 5 bars of pressure grow 16 fold into a high performance giant operating at 80 bars. With an integrated dual-purpose heating or cooling zone it even allows the production of high gloss laminate by cooling under maintained pressure. And with 80 bars of surface pressure it can produce true HPL continuously rendering the decade long controversy meaningless whether continuous laminate CPL can reach the same level of quality as HPL produced on a daylight press. We are going to discuss the evolution of the isobaric high performance double belt press.
