Abstract
A process for manufacturing a board element including at least one cavity in a rear side thereof. The process includes providing a substrate including a thermoplastic material, wherein the substrate includes a substrate portion, and creating the at least one cavity in a rear side of the substrate by impressing the substrate portion by an impression device including at least one protruding impression element, thereby obtaining the board element. The substrate portion is disposed at an elevated temperature (TS) of 40-295° C. when creating the at least one cavity. The process includes creating at least one tapering cavity by means of at least one tapering impression element.
