Veneered component for automobiles, planes and component mfr. - has visible surface of veneer placed against tool surface with resin injected at specified temp. and pressure

摘要

The invention relates to a veneered product and a process for mfr.. A wood veneer is placed with the outer, visible surface against the surface of a tool and after tool closure, the cavity is fed with a fluid, curable polymer, typically a two-part PU, under a pressure of at least 10 bar and a temp. of more than 100 deg.C.. The veneer is pressed against the tool surface, adopts the surface profile and is bonded to the polymer carrier when cured. The polymer may be formed or contain a filler e.g. glass fibres. The wood veneer (18) is positioned with the ultimately visible surface (42) against the profiled surface of a lower tool half (12) and is held in position by extracting air through channels (20,22). USE/ADVANTAGE - The process produces components with a decorative wood surface for automobiles, planes, ships, is simple has less working steps and produces a direct bond between veneer and carrier.
