The invention relates to a method for manufacturing solid, hollow or open profiles, particularly profiles having sharp edges made of polystyrene. The method comprises the following steps: dosing polymers containing polystyrene and, optionally, other *** additives and admixtures ***; plasticizing the components in an extruder in order to obtain a homogeneous mixture; injecting a pressurized gas via an injection port; working this homogeneous mixture and gas and placing them under pressure until a complete dissolution of the gas ensues in order to obtain a single-phase mixture; progressively cooling this single-phase mixture whereby maintaining the necessary pressure for the solubilization of the gas; transferring the single-phase mixture into a shaping tool in order to form a foam; transferring the foam formed thereby through a sizing system whose temperature is optionally controlled, and; motor-drawing the sized foam.
