The lamination process of thick sheet for exterior body panels of automobiles

摘要

Invention patent: b "rolling process of thick sheet for exterior body panels of automobiles" d .A coating of paint exterior quality automotive is laminated on the surface of a car body panel element of plastic material.A film transfer of dry ink is first rolled into a sheet of reinforcing resinous termoformu00e1vel semi rigid, relatively thin.The side of sheet of reinforcement of the resulting laminate is then rolled into a sheet of substrate termoformu00e1vel relatively thick, comprising the polymeric material or a compatible.The two sheets are joined by the extrusion of sheet of substrate thick and use of heat extrusion, so the laminar sheet of thin sheet substrate enhanced in extruded thicker.The resulting laminate sheet thick is then thermoformed, preferably by heating the first laminate to a temperature of formation.Followed by the formation of vacuum laminate in a three-dimensional shape of the finished motor part, such as an instrument panel, ready for placement in a vehicle.
