A shaped, sealed sandwich product is manufactured by press hardening of a sandwich blank consisting of two sheets (12, 13) with spacer material (14) and solder lying in between. The edges of the blank are excepted from the spacer material and the edges are pressed together in the press hardening so that the sheet edges are sealingly joined without spacer material. Alternatively, there is a sealing rim with spacer material along the edges. |
