Abstract

Manufacturing process for open or closed hollow bodies consisting of two layers of thermoplastic materials, of the type in which open molds are heated to a temperature higher than the melting temperature of the thermoplastic material that constitutes the outer layer of the hollow body, they are filled then for a certain time, these powder molds of said thermoplastic material, the excess powder that has not melted being evacuated by any convenient means known per se, characterized in that the mold coated with said thermoplastic material is eventually heated again and then subjected to an electrostatic spray of a second thermoplastic material that melts and forms a continuous thin film in contact with the first layer of thermoplastic material.
