摘要

The low pressure casting machine (21), especially for the production of motor vehicle castings (22) from an aluminum or magnesium alloy, has a casting system of an insulation material at least in zones. A sleeve liner of a ceramic material is inserted into the rising tube (30) for the molten metal (11) in the pressure chamber (10) into the mold. The insulation is mainly of calcium silicate or a compound ceramic/fiber material. The liner sleeve can be of silicon nitride (SiN),.
