Abstract
The invention relates to an intra-mould injection molding method for a finished product with metal surface and the finished product. The intra-mould injection molding method comprises the following steps: a metal sheet with the outer surface and the inner surface is provided; the inner surface of the metal sheet is coated with a buffer layer for heat insulation; a viscose glue layer is coated on the metal sheet in order that the buffer layer is between the metal sheet and the viscose glue layer; the metal sheet coated with the buffer layer and the viscose glue layer is positioned inside an injection molding mould; the outer surface of the metal sheet faces to the inner wall of the mould; and the metal sheet is subjected to injection molding to obtain a combination body combined by the metal sheet and injection plastic. The finished product comprises a metal layer, the buffer layer, the viscose glue layer and a plastic layer. Before carrying out intra-mould injection molding on the metal sheet, the buffer layer is coated on the metal sheet; and the buffer layer can obstruct high temperature from the mould and liquid plastic in hot press molding and intra-mould injection, avoids producing thermal expansion and cold contraction of the metal sheet and provides a good agglutination medium between the metal sheet and the viscose glue layer, thereby improving the stability of agglutination between the metal sheet and the plastic.
