Technique and mechanical assembly to form parts with shaped in surface

A vehicle inside trim segment incorporates a formed substrate overlaid onto a coversheet including a froth backing and a skin film having a surface. The cover sheet is preheated so the skinfilm is in a dissolved gooey fluid state over its softening temperature and the froth backing stays in astrong versatile froth state beneath its liquefying temperature. The preheated cover sheet is mechanicallypre-shaped by a back form into a front form. Pressurized air is connected through the back shape, to ruinform the disguise sheet against the front form, so the liquefied skin film imitates a surface of the frontshape surface while the strong froth backing goes about as a cradle and air boundary layer. Vacuum isconnected through the front form surface. The form is opened, a substrate is presented, and the backshape at that point molds and thermally covers the substrate against the froth support of the cover sheet.
