发明名称 Molding system and article
摘要 A molding system for molding hollow bodies and an article, such as a pallet, produced by means of such system. In a preferred form, the pallet is a rectangular parallelepiped hollow molding and is specifically shaped during molding, to be substantially stiffened by means of its shape and to receive and support one or more blades of a lifting and handling device. In one form, one or more stiffening members extend across the hollow molding and are retained therein as a result of having the molding material molded about the stiffening members. In another form, two stiffening members are provided, each extending along a respective border portion of the hollow molding parallel to the other stiffening member. The invention is also concerned with a method for molding large hollow bodies by means of a fast setting resin which is premixed just before it is introduced into a mold.
