The production process of High Pressure Laminate
High Pressure Laminate is produced through a machine called a Multi Daylight Press, the daylight press gains its name from the ‘daylight’ that can be viewed between each press section.
The multi-daylight hot pressing lines with 2 or 3 layers provide for the simultaneous loading into the press of multiple panels by means of a multi-level automatic loader.
Different sizes, specific pressure and number of daylights are available, depending on the production needs and requirements. The line can feature an individual multi-daylight press or as two independent superimposed multi-daylight presses, both served by a single loader.
A good quality HPL is made under immense pressure with the machine running at greater than 1000 bars of pressure. To put that in perspective the espresso coffee machine at your local café runs at between 9 – 12 bars of pressure, and your average household bathroom taps flow at around 0.1 to 0.2 bars of pressure.
High Pressure Laminate in principle consists of various layers of resin impregnated paper, bonded to one homogeneous sheet under high pressure and temperature.
