The metallic mold has high thermal conductivity. Mating surfaces of its two opposite halves (11, 13), are explosively-clad with a metallic layer (29) of greater wear resistance, at least around the mold cavity (16). Note: mold halves are not necessarily equal and may be further split. Preferred features: Cladding thickness is at least 2 mm. The mold body (11, 13) is a comparatively soft metal. Each mold half (12) has cutting edges (27, 28) around the molding cavity (16). The cutting edges are at least 0.1-1.5 mm wide. They are located in the pinch region of the mold halves. Each contact region includes cooling bores. These extend without additional sealing, from the explosively-clad layer, into the mold halves. Each mold half is in two- or three pieces. |
