A method of manufacturing a door skin (16) includes the steps of providing a wood composite flat blank (10). The blank (10) is placed between the platens of a heated press, the platens being heated to a temperature sufficient to soften the resins in the blank (10) and to thereby soften the blank (10). Sufficient pressure is applied to close the platens and thereafter the pressure is cyclically applied to increase pressure levels for thereby causing the blank (10) to be deformed into a molded shape determined by the configuration of the platens. The molded blank (10) is then removed from between the platens.

L'invention a trait à un procédé de fabrication de revêtement de porte (16) lequel procédé consiste à constituer une ébauche plate (10) en matériau composite à base de bois, à placer cette ébauche (10) entre les plateaux d'une presse chauffée, ces plateaux étant chauffés à une température suffisante pour amollir les résines se trouvant dans l'ébauche et, partant, pour ramollir l'ébauche elle-même. On applique alors une pression suffisante pour rapprocher les plateaux, cette pression étant ensuite appliquée de manière cyclique à des niveaux de pression accrus afin de déformer l'ébauche (10) et de lui donner, par moulage, une forme déterminée par la configuration des plateaux. L'ébauche moulée (10) est alors retirée des plateaux.
