Abstract

La présente invention concerne une pièce moulée en copeaux de bois (14) dans laquelle un périmètre densifié et/ou aminci entoure un trou (15) formé dans la pièce. Le procédé de fabrication de la pièce précitée consiste à rétrécir la cavité de moule entourant le trou et/ou à former sur un perforateur de trous (17) un épaulement qui est projeté au-delà de la surface du moule afin de comprimer davantage les copeaux de bois à proximité du trou.
