Anytime a flat sheet is drawn above a contoured floor, the fabric will almost certainly stretch. A contoured component features a surface area location greater than that of a flat sheet of a similar length and width.
Tooling Design Criteria: These elements as drafts, undercuts, corner radii, cutouts, holes and slots must be regarded as when planning tooling. Woman molds don't theoretically require any draft apart from for Solid elimination in developing the mold. Surely, having said that, plenty of draft is needed to prevent the texturing from abrading in the event the thermoformed portion is removed from the mold.
