The Production Process
Behind the apparent simplicity of high-pressure laminates lies a highly-evolved technology requiring powerful production facilities as well as a sizable investment in research and development.
The HPL production cycle is regulated by European legislation EN 438 and ISO 4586, which establish requirements and production standards. At Arpa Industriale, quality controls occur at every stage of the process: from the selection of raw materials to the paper impregnation, to thermo-lamination, up to the testing and classification of the finished surfaces.
High Pressure Lamination
Thermal lamination is the irreversible process which gives origin to HPL: the impregnated sheets of decorative and kraft paper undergo a simultaneous pressing and heating process at high temperatures.
The process provides the flowing of the thermosetting resins through the paper fibers and its subsequent curing to obtain a homogenous and non-porous material (> 1.35 g/cm³).
Multi-daylight Press:
Temperature 140°/150° C
Pressure > 7 MPa
Press Cycle 40/50 minutes
There is a quality control check at the end of the production process.
