摘要

Mold for the manufacture of "semi-tubes" of insulating material for tubing, in which the insulation comes from fiberglass or rock and resins polymerizable with hot air, characterized by the fact of comprising a male and female mold that determine a cavity of molding extending 360 around a central axis; these male and female molds have a relatively thin wall with holes for the passage of hot air intended for the polymerization of said resin and mineral fibers, in order to provide a molded product capable of being cut along radial planes to produce complete insulating tubes by juxtaposing the two semi-tubes.
