Shaping machine and inductively heating method

A shaping machine includes a melting vessel, an induction coil arranged on the melting vessel for inductively heating, in particular melting, a material, and a shaping cavity. The melting vessel has at least one irradiation region which is substantially permeable for an electromagnetic field, and the shaping machine is adapted to cool the material in the cavity in such a way that a substantially crystalline solid body is formed. A body with a higher magnetic permeability than the melting vessel is arranged overlapping the irradiation region, and the induction coil is arranged between the body and the irradiation region. 种成型机，包括熔化容器(2)、设置在熔化容器(2)上用于感应加热特别是熔化材料的感应线圈(3)、以及成型空腔(4)，其中，熔化容器(2)具有电磁场基本上可穿透的至少个辐射区域(5)，该成型机构造为，对空腔(4)内的材料进行冷却，以致形成基本上结晶的固体，其中，与辐射区域(5)重叠地设置有块体(6)，该块体与熔化容器(2)相比具有更高的透磁率，并且感应线圈(3)是设置在块体(6)和辐射区域(5)之间。
