Abstract

L'invention concerne un procédé de production d'un article moulé, qui permet de réutiliser des fragments d'un bois artificiel dans un article moulé, et qui permet également de produire facilement l'article moulé. Des fragments broyés dans une étape de broyage (S1) sont mélangés à une résine polyester non saturée et à un agent durcissant pour produire un mélange (une étape de mélange (S2)). Ensuite, le mélange est mis sous pression par l'intermédiaire de la première étape de mise sous pression (S3) et de la seconde étape de mise sous pression (S4), ce qui permet de produire l'article moulé. De cette manière, les fragments peuvent être réutilisés dans un article moulé. Dans le procédé, le processus de recyclage est simple, et l'article moulé peut par conséquent être produit facilement.
