Abstract
A low pressure casting machine consists of a warming furnace, to which a pressurised gas can be applied, which is linked by a riser to a casting mould. The latter consists of two parts which can be hydraulically lifted and lowered. The supporting arms for the lower part carry two lower mould halves, at an angle of 60-90 degrees from each other. They are fixed to a column which can be lifted and raised as well as rotated. This raises productivity considerably because one lower mould part can be prepd. by mounting the sand core while the other is being filled with molten metal.
