ACE-TEC : a polystyrene blank is covered with fibreglass layers which is then impregnated with resin before being moved to a mould containing two prepared thermomoulded ASA finishing sheets. The mould is pressure-sealed, then cooled, the finished product extracted and sent for finishing.
TOUGH-TEC : under heat and pressure in aluminum molds we thermoform a durable, impact resistant skin over a molded, watertight EPS foam core. The board is then extracted from the mold and sent for finishing.
The principle : a tube of extruded (molten) polyethylene is gravitymoulded and then shaped by being blown against the inner walls of its hollow mould. Next it’s cooled, taken out of the mould and moved to a steel shaper where it is expansion-filled with high density polyurethane foam.
